$re = '/^[ \s\0\x0B]+|[ \s\0\x0B]+$/m';
$str = ' cat
|-- Usage Example --|
Javascript:
" Your string ".replace( /^[ \\s\\0\\x0B]+|[ \\s\\0\\x0B]+$/g , \'\' );
function trim( str ){
return str.replace( /^[ \\s\\0\\x0B]+|[ \\s\\0\\x0B]+$/g , \'\' );
}
PHP:
preg_replace( \'^[ \\s\\0\\x0B]+|[ \\s\\0\\x0B]+$/\' , \'\' , " Your string " );
function trim( $str="" ){
return preg_replace( \'^[ \\s\\0\\x0B]+|[ \\s\\0\\x0B]+$/\' , \'\' , $str );
}
Output: "Your string"';
preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0);

var_dump($matches);
