This function trims regular expressions from strings.
<?php
function preg_trim( $string, $pattern ) {
$pattern = array( "/^" . $pattern . "*/", "/" . $pattern .
"*$/" );
return preg_replace( $pattern, "", $string );
}
?>
The following example outputs "Hello, world":
<?php
$hello = " ...%20Hello, world!";
echo preg_trim( $hello, "[^a-zA-Z]" );
?>
