Question

trying to replace string once and getting this error would appreciate any help.

$link = '<a href="'.$url.'" title="'.$anchor.'">'.$anchor.'</a> ';
$text = preg_replace(/" ".$anchor." "/,"", $text,1);

Getting this error message:

Error[2]: preg_replace(): Delimiter must not be alphanumeric or backslash

Any idea? All I want is just to replace the first occurrence of text with a link

Answer 1

$link = '<a href="'.$url.'" title="'.$anchor.'">'.$anchor.'</a> ';
$text = preg_replace("/ ".$anchor." /" ,"" , $text , 1 );
// If the spaces were intended
// OR
$text = preg_replace("/".$anchor."/" ,"" , $text , 1 );
// If you do not mean for the anchor to have a space before and after it.

The regular expression segment for these must be a string or an array of strings.
