[SOLVED] Using PHP and URLdecode on multiple pages - starting from scratch

MrLarkins · August 14, 2009

Hello,

My problem:

I have many pages that have urlencoding.

I'd like to write a script that will open all the files in a folder and subsequent sub-folders that are .html extension and urldecode them and overwrite the original with the decoded.

Is this going to be hard for me? Where do I start?

Is this going to be hard for me?

Wouldn't know.

Where do I start?

glob, file_get_contents and file_put_contents.

MrLarkins · August 15, 2009

how about this? i was working on this while you were posting

<?php
$current_dir = "$DOCUMENT_ROOT"."algebra1/";
  $dir = opendir($current_dir);    

  while ($file = readdir($dir))
    {
    $parts = explode(".", $file);
    if (is_array($parts) && count($parts) > 1) { 
        $extension = end($parts);        
        if ($extension == "html")    
             $html_file=fopen("$file","r+");
              urldecode($html_file);
fclose($html_file);
        } 
    } 
  
  closedir($dir);
?>

Warning: fclose(): supplied argument is not a valid stream resource in /home/oskgamin/public_html/MrLarkins.com/urldecode.php on line 15

Warning: fopen(footer.html) [function.fopen]: failed to open stream: No such file or directory in /home/oskgamin/public_html/MrLarkins.com/urldecode.php on line 11

guess not...whats that stuff mean?

trq · August 15, 2009

foreach (glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html' as $file) {
  file_put_contents($_SERVER['DOCUMENT_ROOT'] . "/algebra1/$file", urldecode(file_get_contents($_SERVER['DOCUMENT_ROOT'] . "/algebra1/$file")));
}

MrLarkins · August 15, 2009

again, i was working while you were posting, lol...and it seems yours is shorter than mine. I'm going to try yours, but please take a look at mine and tell me where i went wrong...b/c it makes logical sense to me but doesn't work.

<?php
$current_dir = "$DOCUMENT_ROOT"."algebra1/";
  $dir = opendir($current_dir);    

  while ($file = readdir($dir))
    {
    $parts = explode(".", $file);
    if (is_array($parts) && count($parts) > 1) { 
        $extension = end($parts);        
        if ($extension == "html")    
             $encoded=file_get_contents($file);
	$decoded=urldecode($encoded);
             file_put_contents($file,$decoded);

        } 
    } 
  
  closedir($dir);
?>

edit**

yours give an error

Parse error: syntax error, unexpected T_AS in /home/oskgamin/public_html/MrLarkins.com/urldecode.php on line 2

trq · August 15, 2009

Simple mistake.

foreach (glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
  file_put_contents($_SERVER['DOCUMENT_ROOT'] . "/algebra1/$file", urldecode(file_get_contents($_SERVER['DOCUMENT_ROOT'] . "/algebra1/$file")));
}

MrLarkins · August 15, 2009

lol, yours is returning the same errors as mine...i don't feel so dumb now

failed to open stream: No such file or directory

trq · August 15, 2009

What does this produce?

<pre>
print_r(glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html'));
</pre>

MrLarkins · August 15, 2009

<?php

<pre>
print_r(glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html'));
</pre>

?>

produces

Parse error: syntax error, unexpected '<' in /home/oskgamin/public_html/MrLarkins.com/urldecode.php on line 3

while

<pre>
print_r(glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html'));
</pre>

produces

print_r(glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html'));

Markh789 · August 15, 2009

Because it contains HTML, set the tags outside.

<pre>

<?php

print_r(glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html'));

?>

</pre>

MrLarkins · August 15, 2009

ok, thanks.

here's the output

Array
(
    [0] => /home/oskgamin/public_html/MrLarkins.com/algebra1/footer.html
    [1] => /home/oskgamin/public_html/MrLarkins.com/algebra1/globalnavigation-cd.html
)

and yes, those are the only two files

but keep in mind, there are many other folders with many other html files in there that need to be urldecoded

and of course this is the full error message

MrLarkins · August 15, 2009

i modified your code and it seemed to work


<?php

foreach (glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
  file_put_contents("$file", urldecode(file_get_contents("$file")));
}

?>

but how do i get it to work into the subdirectories as well?

MrLarkins · August 15, 2009

I had to modify the code a bit to strip out some now un-needed scripting garbage

new code still does not did into the lower directories and do its magic!

<?php

foreach (glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
$decode=urldecode(file_get_contents("$file"));
$s1=str_replace('<SCRIPT LANGUAGE="Javascript"><!--
document.write(unescape("',"",$decode);
$s2=str_replace('"));//--></SCRIPT>',"",$s1);
$s3=str_replace('<SCRIPT LANGUAGE="Javascript"><!--
document.write(unescape("',"",$s2);
$s4=str_replace('<SCRIPT LANGUAGE="JavaScript"><!--
eval(unescape("document.write=null;',"",$s3);
  file_put_contents("$file","$s4");
}

?>

MrLarkins · August 16, 2009

still working on it, still having problems

here's what i got so far

<?php

$current_dir = glob($_SERVER['$DOCUMENT_ROOT']."algebra1/");
  foreach($current_dir as $dir) {
  $dir1 = opendir($dir);    

  while ($file = readdir($dir1))
    {
    $parts = explode(".", $file);
    if (is_array($parts) && count($parts) > 1) { 
        $extension = end($parts);        
        if ($extension == "html")   
$decode = urldecode(file_get_contents($file));
	$s1 = str_replace('<SCRIPT LANGUAGE="Javascript"><!--
	             document.write(unescape("',"",$decode);
	$s2 = str_replace('"));//--></SCRIPT>',"",$s1);
	$s3 = str_replace('<SCRIPT LANGUAGE="Javascript"><!--
                          document.write(unescape("',"",$s2);
             $s4 = str_replace('<SCRIPT LANGUAGE="JavaScript"><!--
		eval(unescape("document.write=null;',"",$s3);
  	file_put_contents($file,$s4);

}
}
}
?>

MrLarkins · August 17, 2009

I'm still having problems. :confused: My code gives the following:

Warning: file_put_contents(.) [function.file-put-contents]: failed to open stream: Is a directory in /home/oskgamin/public_html/MrLarkins.com/urldecode.php on line 21

Warning: file_put_contents(..) [function.file-put-contents]: failed to open stream: Is a directory in /home/oskgamin/public_html/MrLarkins.com/urldecode.php on line 21

what is with the 'file_put_contents(.)' and 'file_put_contents(..)' ?

thebadbad · August 17, 2009

. and .. represent the current and parent directory I believe. They're included when using readdir(), so you have to skip them in your code (or use the simpler glob() exclusively).

MrLarkins · August 17, 2009

(or use the simpler glob() exclusively).

i tried using the glob() first, but it didn't dig into the subdirectories...or did i do it wrong? thorpe helped with it

again, this is what was used


foreach (glob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
  file_put_contents($_SERVER['DOCUMENT_ROOT'] . "/algebra1/$file", urldecode(file_get_contents($_SERVER['DOCUMENT_ROOT'] . "/algebra1/$file")));
}

but it only returned the files in the immediate folder, not all the other files in the subdirectories

thebadbad · August 17, 2009

You will need to call glob() recursively, to dig into subdirectories. There's a user function on the manual page.

MrLarkins · August 17, 2009

You will need to call glob() recursively, to dig into subdirectories.

sorry, but I have no idea how to ...

There's a user function on the manual page.

:wtf: because that all looks like gibberish to me...i wish i were smarter. :facewall:

believe it or not, I am trying.

thebadbad · August 17, 2009

No worries. Here's an example using that user function:

<?php
function rglob($pattern, $flags = 0, $path = '') {
if (!$path && ($dir = dirname($pattern)) != '.') {
	if ($dir == '\\' || $dir == '/') {
		$dir = '';
	}
	return rglob(basename($pattern), $flags, $dir . '/');
}
$paths = glob($path . '*', GLOB_ONLYDIR | GLOB_NOSORT);
$files = glob($path . $pattern, $flags);
foreach ($paths as $p) {
	$files = array_merge($files, rglob($pattern, $flags, $p . '/'));
}
return $files;
}

foreach (rglob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
//file_put_contents($file, urldecode(file_get_contents($file)));
echo "$file<br />";
}
?>

I'm not too sure about the paths used in the foreach loop, so it prints them for now so you can check if they are right, before you modify the files.

MrLarkins · August 17, 2009

wow! that shows a lot of files! i knew there would be a bunch, just didn't realize how many. see for yourself. ( over a 1000 )

and now i'm wondering about the string replacement that i need to do on all these files. can i do it like

<?php
function rglob($pattern, $flags = 0, $path = '') {
if (!$path && ($dir = dirname($pattern)) != '.') {
	if ($dir == '\\' || $dir == '/') {
		$dir = '';
	}
	return rglob(basename($pattern), $flags, $dir . '/');
}
$paths = glob($path . '*', GLOB_ONLYDIR | GLOB_NOSORT);
$files = glob($path . $pattern, $flags);
foreach ($paths as $p) {
	$files = array_merge($files, rglob($pattern, $flags, $p . '/'));
}
return $files;
}

foreach (rglob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
file_put_contents($file, urldecode(file_get_contents($file)));
file_put_contents($file, str_replace('<SCRIPT LANGUAGE="Javascript"><!--        
document.write(unescape("',"",file_get_contents($file)));

}
?>

thebadbad · August 17, 2009

You would do it like this:

<?php
$replace = array(
'<SCRIPT LANGUAGE="Javascript"><!--
                   document.write(unescape("',
'"));//--></SCRIPT>',
'<SCRIPT LANGUAGE="Javascript"><!--
                             document.write(unescape("',
'<SCRIPT LANGUAGE="JavaScript"><!--
         eval(unescape("document.write=null;'
);
foreach (rglob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
$data = urldecode(file_get_contents($file));
$data = str_replace($replace, '', $data);
file_put_contents($file, $data);
}
?>

MrLarkins · August 17, 2009

tried it, and it says it did it, but the files still show the code that wasn't replaced. i'm checking the strings that need to be replaced character by character.

thebadbad · August 17, 2009

If it's because of the many spaces, you could try with regular expressions:

<?php
$replace = array(
'~<SCRIPT LANGUAGE="Javascript"><!--\s*document\.write\(unescape\("~i',
'~"\)\);//--></SCRIPT>~i',
'~<SCRIPT LANGUAGE="Javascript"><!--\s*document\.write\(unescape\("~i',
'~<SCRIPT LANGUAGE="JavaScript"><!--\s*eval\(unescape\("document\.write=null;~i'
);
foreach (rglob($_SERVER['DOCUMENT_ROOT'] . '/algebra1/*.html') as $file) {
$data = urldecode(file_get_contents($file));
$data = preg_replace($replace, '', $data);
file_put_contents($file, $data);
}
?>
