PHP: Best way to extract text within parenthesis?

Question

What\'s the best/most efficient way to extract text set between parenthesis? Say I wanted to get the string \"text\" from the string \"ignore everything except this (text)\"

Answer 1

This function may be useful.

    public static function getStringBetween($str,$from,$to, $withFromAndTo = false)
    {
       $sub = substr($str, strpos($str,$from)+strlen($from),strlen($str));
       if ($withFromAndTo)
         return $from . substr($sub,0, strrpos($sub,$to)) . $to;
       else
         return substr($sub,0, strrpos($sub,$to));
    }
    $inputString = "ignore everything except this (text)";
    $outputString = getStringBetween($inputString, '(', ')'));
    echo $outputString; 
    //output will be test

    $outputString = getStringBetween($inputString, '(', ')', true));
    echo $outputString; 
    //output will be (test)

strpos() => which is used to find the position of first occurance in a string.

strrpos() => which is used to find the position of first occurance in a string.
