How Can I Replace PHP's Deprecated `each()` Function?

Adapting Code from Deprecated each() Function

With PHP 7.2, the each() function has been marked as deprecated. This article provides alternative solutions for updating code that utilizes this now-discouraged function.

Examples and Solutions:

1. Assigning Values Using key() and current()

$ar = $o->me;
$typ = key($ar);
$val = current($ar);

2. Using key() and current() to Obtain Key-Value Pairs

$out = ['me' => [], 'mytype' => 2, '_php_class' => null];
$expected = [key($out), current($out)];

3. Employing foreach() Loop for Key-Value Assignment

foreach ($broken as $k => $v) {
     $kv = [$k, $v];
}

4. Current Element Assignment via current()

$this->result = current($this->cache_data);

5. Iteration with for() Loop and next() for Cursor Advancement

reset($array);
for ($i = 0; $i < 30; $i++) {
    $id = key($array);
    $item = current($array);
    next($array);
}

By implementing these alternative approaches, developers can effectively update their code to avoid using the deprecated each() function, ensuring compatibility with PHP 7.2 and beyond.
