I\'m trying to do a PHP regular expression but i can\'t find the right way ...

Imagine I have this string: \"hello, my {{name is Peter}} and {{I want to eat chocolat

Answer 1

This worked for me.

$subject = 'Hello {{name}}, here is an email {{email}} and phone # {{phone}}';
$replace = array(
    '{{name}}' => 'Bob',
    '{{email}}' => 'email@me.com',
    '{{phone}}' => '5155554455'
);

$output = preg_replace_callback('{{{?(#[a-z]+ )?[a-z]+.[a-z]*}?}}', function($match) use ($replace) {
    if(isset($replace[$match[0]])){
        return ($replace[$match[0]]);
    } else {
        return($match[0]);
    } 
}, $subject);

var_dump($output);
