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.
