pHP 5.6 preg_replace /e deprecated stripslashes

  • on a very old WP install (2.0) I need to upgrade PHP to 5.6 (provider). Don’t want to put much effort in the site (upgrade WP).
    I only need to change this line to a callback function – as a non-coder, I don’t know how!:
    $pee = preg_replace('!(<pre.*?>)(.*?)</pre>!ise', " stripslashes('$1') . stripslashes(clean_pre('$2')) . '</pre>' ", $pee);?
    This is an example but I can’t adapt to my line.

    Any help much appreciated!

    Here is the equivalent using preg_replace_callback():

    $pee = preg_replace_callback('!(<pre.*?>)(.*?)</pre>!is', function($matches) {
	return $matches[1] . clean_pre($matches[2]) . '</pre>';
}, $pee);

    If you plan to use this code in a newer version of WordPress, be aware that the clean_pre() function was deprecated a long time ago (v3.4). Details:

    wow wow wow! works! thx so much!
    and thx for the warning, the site hopefully runs some more years without updating…

    Now another error (but working):

    Strict Standards: Only variables should be assigned by reference in /kunden/xxx/webseiten/wp-includes/functions.php on line 590 and 696

    l 590:
    $_post = & $wpdb->get_row($query);
    l 696
    $_page = & $wpdb->get_row($query);

    another follow-up error (but working):

    Warning: Cannot modify header information – headers already sent by (output started at /kunden/xxx/webseiten/wp-includes/functions.php:590) in /kunden/xxx/webseiten/wp-admin/post.php on line 60

    line 57-60 is:

    if ( isset($_POST['save']) )
	$location = "post.php?action=edit&post=$post_ID";

header("Location: $location");
