[RESOLVED] removing php code from a file

@so_is_thisOct 22.2006 — #Once you've read in the file content (and as long as the opening and closing PHP tags are adhered to), the something like this should work (untested):

[code=php]
 $result = preg_match_all('/<?.*?>/s', $content, $matched_content);
 $stripped_content = preg_replace('/<?.*?>/s', '', $content);
 [/code]

@Sid3335authorOct 22.2006 — #works when the php code is on a single line, but not if there is a linefeed.

my regular expression knowledge is non-existant

@bokehOct 22.2006 — #The code above would fall over if any <?xml tags are present.

The following disassembles and reassembles the posted example. Would be better in object context.

[code=php]<?php
 
 header('Content-Type: text/plain');
 
 $source_file = 'test.txt';
 
 $destinationHTML = 'test2.txt';
 $destinationPHP = 'test3.txt';
 
 $reassembled = 'test4.txt';
 
 
 # disassemble and save to two files
 $contents = file_get_contents($source_file);
 preg_match_all('/<?php.*??>/is', $contents, $matches);
 $handle = fopen($destinationPHP, 'w') or die('I could not open: ' . $destinationPHP);
 fwrite($handle, serialize($matches[0]));
 fclose($handle);
 
 $handle = fopen($destinationHTML, 'w') or die('I could not open: ' . $destinationHTML);
 fwrite($handle, preg_replace_callback('/<?php.*??>/is', 'first_callback', $contents));
 fclose($handle);
 
 #reassemble and save to one file
 $HTML = file_get_contents($destinationHTML);
 $PHP = file_get_contents($destinationPHP);
 $handle = fopen($reassembled, 'w') or die('I could not open: ' . $reassembled);
 second_callback(null, true, $PHP);
 fwrite($handle, preg_replace_callback('/<!-- code section (d+) -->/', 'second_callback', $HTML));
 
 echo 'done';
 
 function first_callback($in, $reset = false)
 {
 static $count = 0;
 if($reset === true) 
 {
 $count = 0;
 return null;
 }
 return '<!-- code section '.($count++).' -->';
 }
 
 function second_callback($in, $reset = false, $PHP = null)
 {
 static $count = 0;
 static $code;
 if($reset === true) 
 {
 $count = 0;
 $code = unserialize($PHP);
 return null;
 }
 if(isset($code[$in[1]]))
 {
 return $code[$in[1]];
 }
 return $in[0];
 }
 
 ?>[/code]
