I want to parse shortcode like Wordpress with attributes:

I need output as array, function na

Answer 1

I also needed this functionality in my PHP framework. This is what I've written, it works pretty well. It works with anonymous functions, which I really like (it's a bit like the callback functions in JavaScript).

Hello, my name is John an my age is [calc-age day="4" month="10" year="1991"].
';
$content .= '
Hello, my name is Carol an my age is [calc-age day="26" month="11" year="1996"].
';

//The array with all the shortcode handlers. This is just a regular associative array with anonymous functions as values. A very cool new feature in PHP, just like callbacks in JavaScript or delegates in C#.
$shortcodes = array(
    "calc-age" => function($data){
        $content = "";
        //Calculate the age
        if(isset($data["day"], $data["month"], $data["year"])){
            $age = date("Y") - $data["year"];
            if(date("m") < $data["month"]){
                $age--;
            }
            if(date("m") == $data["month"] && date("d") < $data["day"]){
                $age--;
            }
            $content = $age;
        }
        return $content;
    }
);
//http://stackoverflow.com/questions/18196159/regex-extract-variables-from-shortcode
function handleShortcodes($content, $shortcodes){
    //Loop through all shortcodes
    foreach($shortcodes as $key => $function){
        $dat = array();
        preg_match_all("/\[".$key." (.+?)\]/", $content, $dat);
        if(count($dat) > 0 && $dat[0] != array() && isset($dat[1])){
            $i = 0;
            $actual_string = $dat[0];
            foreach($dat[1] as $temp){
                $temp = explode(" ", $temp);
                $params = array();
                foreach ($temp as $d){
                    list($opt, $val) = explode("=", $d);
                    $params[$opt] = trim($val, '"');
                }
                $content = str_replace($actual_string[$i], $function($params), $content);
                $i++;
            }
        }
    }
    return $content;
}
echo handleShortcodes($content, $shortcodes);
?>

The result:
Hello, my name is John an my age is 22.
Hello, my name is Carol an my age is 17.
