Inserting Array Elements in a Loop in PHP
You can also insert elements while iterating through arrays with a loop:
<?php
$arr = [1, 2, 3, 4, 5];
foreach ($arr as $elem) {
echo "xxx $elem yyy";
}
?>
Simplify the following code:
<?php
$arr = ['a' => 1, 'b' => 2, 'c' => 3];
foreach ($arr as $key => $elem) {
echo 'pair: ' . $elem . ' ' . $key . '<br>';
}
?>
