Issue with preg_replace, e modifier inside PHP classes

JdS · #1 31-May-2003, 04:41

Recently, I had an issue with using preg_replace() with the e modifier inside a class. For example, if you were to save the sample code below to a file named test.php and view it, it doesn't work the way it used to (I am on PHP ver 4.3.1).

FILENAME: TEST.PHP

PHP Code:


<?php
$str = 'The quick brown fox [b][[/b]B]jumped[/b] over the lazy dogs.
        The quick brown fox [b][[/b]B]jumped[/b] over the lazy dogs.
        The quick brown fox [b][[/b]B]jumped[/b] over the lazy dogs.
        The quick brown fox [b][[/b]B]jumped[/b] over the lazy dogs.
        The quick brown fox [b][[/b]B]jumped[/b] over the lazy dogs.';

$t = new Test();
$str = $t->ProcessBB( $str );
echo $str;

class Test
{
  var $str;
  
  function Test()
  {
    // constructor
  }
  
  function ProcessBB( $str )
  {
    $this->str = $str;
    $this->str = preg_replace( '/(\\[b\\])(.+)(\\[\\/b\\])/eisU', "$this->BoldMe('$2')", $this->str );
    return $this->str;
  }
  
  function BoldMe( $s )
  {
    return ( '<strong>'.$s.'</strong>' );
  }
}
?>

Nothing in the string will be in bold!

The funny thing is that I can get it to work if function BoldMe(str) is a regular function outside the class!

this works fine for me on PHP 4.3.3-dev

and it's without the 'e' and it works fine.
btw, you or your host should update there php version.
PHP 4.3.2 is already 2 days old...

Code:

$this->str = preg_replace("/(\[b\])(.+)(\[\/b\])/isU", $this->BoldMe('\\2'), $this->str);

(php tags messup the \\2)

You know what, you're absolutely right. It works without the 'e' modifier! Thank you
