Jak ze stringa zrobić tablice klucz = wartość ?

sender=user8992;session=7wdd49ea5eb118a5215c8c251d2c2a60;algorithm=SHA;content=text

[
  "sender" => "user8992"
  "session" => "7wdd49ea5eb118a5215c8c251d2c2a60"
  "algorithm" => "SHA"
  "content" => "text"
]

<?php
$x = "sender=user8992;session=7wdd49ea5eb118a5215c8c251d2c2a60;algorithm=SHA;content=text";
              
$z = explode(";",$x);
$arr = [];
foreach ($z as $row){
    $y = explode("=",$row);
    $arr[$y[0]] = $y[1];
}

print_r($arr);

//Result
/*

    [sender] => user8992
    [session] => 7wdd49ea5eb118a5215c8c251d2c2a60

*/

$x = "sender=user8992;session=7wdd49ea5eb118a5215c8c251d2c2a60;algorithm=SHA;content=text";
preg_match_all("*([^;=]+)=([^;=]+)*", $x, $m);
$result = array_combine($m[1], $m[2]);
print_r($result);

$string = 'sender=user8992;session=7wdd49ea5eb118a5215c8c251d2c2a60;algorithm=SHA;content=text';
$array = explode(';', $string);

$fn = function ($key, $value): ?array {

    if (count($tmp) !== 2) {
        return null;
    }

    return [$tmp[0], $tmp[1]];
};
$data = array_column(array_map($fn, array_keys($array), $array), 1, 0);
