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

Updating Code to Avoid Using the Deprecated each() Function

In PHP 7.2, the each() function has been deprecated. To avoid using it and continue using your code without encountering deprecation warnings, there are several techniques you can employ:

For assigning values from a key-value pair:

• Use key() and current() to obtain the key and value, respectively.

• Example:

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

Returning the first key-value pair:

• Use key() and current() to store both the key and value in an array.

• Example:

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

Iterating through an array:

• Use a foreach() loop and assign values within the loop.

• Example:

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

Assigning a single value:

• Assign the current value using current().

• Example:

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

Iterating to a specific point:

• Use a for() loop to iterate through the array up to a specific number of times or until the end of the array.

• Example:

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

By incorporating these techniques into your code, you can eliminate the use of the deprecated each() function and ensure compatibility with PHP 7.2 and beyond.
