[SOLVED] Appending Text to Beginning of a .php File

[scubes13]

Hello everyone,

 

I have several directories filled with .php files. I am trying to write a script that will take a string of text and insert this text at the top of each .php file while leaving the remainder of the existing code intact.

 

Here is what I have thus far:

 

<?php

$file_name = "test.php";

if(file_exists($file_name))
{

	// Open file for writng and place pointer at the end
	$handle = fopen($file_name, 'r+');

	if(!$handle) {

		die("Couldn't open file <i>$file_name</i>");

	}

	//place pointer at the beginning of the file.
	//rewind($handle);

	// Echo the existing text for debugging
	$orig_string = fread($handle, filesize($file_name));
	echo $orig_string;

	fseek($handle, 0);

	$string = "<?php\n";
	$string .= "define('QUADODO_IN_SYSTEM', true);\n";
	$string .= "require_once('includes/header.php');\n";
	$string .= '$qls'."->Security->check_auth_page('";
	$string .= $file_name;
	$string .= "');\n";
	$string .= '?'.">\n";

     //write to file
     fwrite($handle, $string);

     echo "Success writing to file.";

}
else
{

	echo "File <i>$file_name</i> doesn't exist.";

}

fclose($handle);

?>

 

My test.php file looks like this:

 

This is a line of text 1
This is a line of text 2
This is a line of text 3
This is a line of text 4
This is a line of text 5
This is a line of text 6
This is a line of text 7
This is a line of text 8
This is a line of text 9
This is a line of text 10
This is a line of text 11
This is a line of text 12
This is a line of text 13
This is a line of text 14
This is a line of text 15

 

Once I run the above code, I get this:

 

<?php
define('QUADODO_IN_SYSTEM', true);
require_once('includes/header.php');
$qls->Security->check_auth_page('test.php');
?>
his is a line of text 6
This is a line of text 7
This is a line of text 8
This is a line of text 9
This is a line of text 10
This is a line of text 11
This is a line of text 12
This is a line of text 13
This is a line of text 14
This is a line of text 15

 

You will notice that it does put the code at the top of the page, but it writes over several lines.

 

Any ideas as to what I am doing incorrectly?

 

Thanks,

You need to save the file contents into a variable. Add the old content to the end of the new content, then write it to the file. fwrite will alway overwrite the same amount of bytes it as the new content. The pointer is at the beginning but it doesn't 'push' the old content down it just overwrites it.

Ok, that makes sense.

 

Any suggestions as how to grab the existing php content without dorking up the formatting? At the moment all of my output is getting shoved onto one continuous line when I try to copy the existing php code from the file.

 

Thanks so much!

If you're using PHP5, you can used the functions file_get_contents() and file_put_contents().

 

<?php

$file_name = "test.php";

if(file_exists($file_name))
{

	// get the contents of the file
	$orig = file_get_contents($file_name);

	$string = "<?php\n";
	$string .= "define('QUADODO_IN_SYSTEM', true);\n";
	$string .= "require_once('includes/header.php');\n";
	$string .= '$qls'."->Security->check_auth_page('";
	$string .= $file_name;
	$string .= "');\n";
	$string .= '?'.">\n";

	$string .= $orig; // append the original contents onto the new string.

     //write to file
	file_put_contents($file_name,$string);
	  
     echo "Success writing to file.";

}
else
{

	echo "File <i>$file_name</i> doesn't exist.";

}
?>

Thanks much. That worked like a charm.

 

I am reading up on file_get_contents and file_put_contents now.

 

Thanks again!

define('QUADODO_IN_SYSTEM', true);

require_once('includes/header.php');

$qls->Security->check_auth_page('test.php');

 

if in every page ur appending this common code where as the param has to be get dynamically u can write this code in a php file and include it in each page but based on the url or Querystring we have to pass the parameter ...
