The each() function is deprecated. This message will be suppressed on further calls

Description

The function each was deprecated in PHP 7.x and removed in PHP 8.0. It was mainly used in loops like the above, and could be replaced advantageously with a foreach structure.

Example

<?php

$array = ['a', 'b'];
while(list($key, $value) = each($array)) {
    print "$key => $value\n";
}

?>

Solutions

  • Replace the while loop with a foreach one.

  • Replace the loop with a call to one of the array function.

  • Traverse the array with a yield or yield from call.

  • Use an iterator to traverse the array.

In more recent PHP versions, this error message is now Call to undefined function each().
