each() Is No More¶
The each function is the base for the while loop that traverse arrays. The modern version of this loop is foreach, which does not rely on each, and improves the loop in speed and reliability. Hence, each was deprecated in PHP 7.4, and removed in 8.0.
PHP code¶
<?php
while(list($k, $v) = each($array)) {
print $k . ' => '. $v.PHP_EOL;
}
?>
