[SOLVED] Replace text with page

[Brandon Jaeger]

How would I take text from a string and replace it with an page (include it)?

 

For example, I'm using regex to find the string:

$str = "This {INCLUDE:page_01.php} is {INCLUDE:page_02.php} some {INCLUDE:page_03.php} text";
preg_match_all("#{INCLUDE:(.*?)}#is", $str, $matches);

 

I want to somehow include the page from the matches exactly where it's located in the string.

 

Is it possible?

 

Thanks,

Brandon

If you have already extracted the file name, just assign it to a variable, then include that variable.

[Brandon Jaeger]

I know that... but I'm having a problem replacing it in the string exactly where its at.

So the file has what, just ordinary text in it or something? You could do it like this:

 

$str = "This {INCLUDE:page_01.php} is {INCLUDE:page_02.php} some {INCLUDE:page_03.php} text";
preg_match_all("#{INCLUDE:(.*?)}#is", $str, $matches);

for($i = 0; $i < count($matches[0]); $i++){
$str = str_replace($matches[0][$i], file_get_contents($matches[1][$i]), $str);
}

echo $str;

[Brandon Jaeger]

It could be any type of file. I'm specifically aiming at including .html and .php files.

[F1Fan]

I'm a little tired, so I apologize if this is a weak answer:

 

<?php
$a = explode('{INCLUDE:',$str);
foreach ($a as $i){
$p = strpos($i,".php");
$p = $p+4;
$include = substr($i,0,$p);
include_once($include);
}
?>

 

Maybe that?

[Brandon Jaeger]

Nope. Thanks anyway... But what I'm trying to achieve is simply replacing that text with the file itself.

 

I might use ProjectFear's method like so:

$str = "This {INCLUDE:page_01.php} is {INCLUDE:page_02.php} some {INCLUDE:page_03.php} text";
preg_match_all("#{INCLUDE:(.*?)}#is", $str, $matches);

for($i = 0; $i < count($matches[0]); $i++){
  $str = str_replace($matches[0][$i], "<?php include(\"" . $matches[1][$i] . "\"); php?>", $str);
}

echo $str;

Would something like that work if the parent page is .php?

[JasonLewis]

What I was wondering is what is IN the file. If you just want to replace the {INCLUDE:file.php} with the contents of file.php then what I posted should do the trick.

 

That code you posted above is different to mine. I used file_get_contents() to get the contents of the file. I don't know if what you have above would work.

[Brandon Jaeger]

It could be anything. An HTML file; PHP script; etc.

 

Would your method allow the execution of a PHP script?

[Brandon Jaeger]

Solved it!

 

Solution:

$str = str_replace($matches[0][$i], include($matches[1][$i]), $str);

I didn't think that was possible, but it is!

 

Thanks a lot for your help F1Fan and ProjectFear

[JasonLewis]

I'm confused, wouldn't that just replace it with a 1 depending on if the file was successfully included, although the contents of the file will still be displayed but they wouldn't be at the position you want them at. ???

[Brandon Jaeger]

Just when I thought I had it solved, I run into yet another problem...

 

	$str = "This {INCLUDE:test.php} is {INCLUDE:page_02.php} some {INCLUDE:page_03.php} text";

$str = str_replace(" ", "<br \>", $str);

preg_match_all("#{INCLUDE:(.*?)}#is", $str, $matches);

$numMatches = count($matches[0]);

for($i = 0; $i < $numMatches; $i++)
	if(file_exists($matches[1][$i]))
		$str = str_replace($matches[0][$i], include($matches[1][$i]), $str);
	else
		$str = str_replace($matches[0][$i], "Couldn't open <b>" . $matches[1][$i] . "</b>", $str);

echo $str;

The first file exists on the server, the other 2 do not.

 

Contents of test.php is a simple 'hello world' script.

 

This is what it prints out:

Hello, world!This

1

is

Couldn't open page_02.php

some

Couldn't open page_03.php

text

 

Notice the positioning and the extra "1".

 

Is there a way to fix this?

 

P.S. This is probably what you're talking about, ProjectFear.  ???

[JasonLewis]

There is probably a better way to achieve what you are trying to do but here is a way of doing it.

I'm assuming your page_01.php page looks like this:

 

<?php
echo "Hello, world!";
?>

 

If it does make it like this:

 

<?php
$return = "Hello, world!";
?>

 

Then you can do this:

 

<?php

$str = "This {INCLUDE:page_01.php} is {INCLUDE:page_02.php} some {INCLUDE:page_03.php} text";
preg_match_all("#{INCLUDE:(.*?)}#is", $str, $matches);

for($i = 0; $i < count($matches[0]); $i++){
if(file_exists($matches[1][$i])){
	include($matches[1][$i]);
	$str = str_replace($matches[0][$i], $return, $str);
}else{
	$str = str_replace($matches[0][$i], "Failed to include <b>".$matches[1][$i]."</b>", $str);
}
}

echo $str;

?>

[Brandon Jaeger]

Not exactly what I'm looking for, but I think I'm going to use it anyway. I wanted it to be able to include ANY PHP script that I'd stick in there, but I think I'm just going to take the PHP scripts, add all of the text to a string, and replace it from there like you just showed me.

 

Thanks a ton! I'll post again if I have anymore problems.

[Brandon Jaeger]

Full code that works 100% (so far at least!):

 

<?php
$str = "This {INCLUDE:test.php} is {INCLUDE:test.html} some {INCLUDE:test.txt} text";

$str = str_replace(" ", "<br \>", $str);

preg_match_all("#{INCLUDE:(.*?)}#is", $str, $matches);

$numMatches = count($matches[0]);

for($i = 0; $i < $numMatches; $i++)
{
$file_name = $matches[1][$i];

if(file_exists($file_name))
{
	if(strpos(GetExt($file_name), ".php") !== FALSE)
	{
		include($file_name);
		$str = str_replace($matches[0][$i], $content, $str);
	}
	else
		$str = str_replace($matches[0][$i], file_get_contents($file_name), $str);
}
else
	$str = str_replace($matches[0][$i], "Couldn't open <b>" . $file_name . "</b>", $str);
}

echo $str;

function GetExt($file)
{
$pos = strrpos($file, '.');
$str = substr($file, $pos);

return strtolower($str);
}
?>

Content of test.php:

<?php
$content = "Hello, world!";
?>
