预期输出

Array
    (
        [FullName] => Thomas Marquez
        [Address] => 1234 Sample Rd, Apt 21, XX 33178
        [Age] => 37
        [Code] => 123
    )

Answer 1

您可以将 preg_match_all() 与此正则表达式一起使用:

/([a-z]+)=([^=]+)(,|$)/i

详情

/
([a-z]+)  match any letter 1 or more times (you can change it to \w if you need numbers
=         match a literal equal sign
([^=]+)   match anything but an equal sign, 1 or more times
(,|$)     match either a comma or the end of the string
/i        case-insensitive flag

像这样:

<?php
$string = "FullName=Thomas Marquez,Address=1234 Sample Rd, Apt 21, XX 33178,Age=37,Code=123";
preg_match_all("/([a-z]+)=([^=]+)(,|$)/i", $string, $m);
var_dump($m[1]); // keys
var_dump($m[2]); // values
var_dump(array_combine($m[1], $m[2])); // combined into one array as keys and values
