提取单引号和双引号字符串

Question

This question is basically the same as How to extract the string in the quotes (either double quotes or single quotes), except in PHP.

Basically, I want a function like this:

function extract_tokens($text) {
    preg_match_all('/Foo\((?:\'(?<text>.*?)\'|"(?<text>.*?)")\)/', $text, $matches);
    return $matches['text'];
}

However, this is not allowed in PHP: PHP Warning: preg_match_all(): Compilation failed: two named subpatterns have the same name.

My current solution seems overly complicated for a simple goal:

function extract_tokens($text) {
    preg_match_all('/Foo\((\'(.*?)\'|"(.*?)")\)/', $text, $matches);
    return array_map(function($token) {
        return substr($token, 1, strlen($token) - 2);
    }, $matches[1]);
}

Answer 1

You can try this:

function extract_tokens($text) {
    preg_match_all('/Foo\(([\'"])(?<text>.*?)\1\)/', $text, $matches);
    return $matches['text'];
}
