php iterate over array code example

Example 1: php loop through array

$clothes = array("hat","shoe","shirt");
foreach ($clothes as $item) {
	echo $item;
}

Example 2: php iterate through array

$arr = ['Item 1', 'Item 2', 'Item 3'];

foreach ($arr as $item) {
  var_dump($item);
}

Example 3: php array loop

for ($i = 0; $i < count($array); $i++) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];
}

Example 4: for each php

<?php
$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
    $value = $value * 2;
}
// $arr is now array(2, 4, 6, 8)

// without an unset($value), $value is still a reference to the last item: $arr[3]

foreach ($arr as $key => $value) {
    // $arr[3] will be updated with each value from $arr...
    echo "{$key} => {$value} ";
    print_r($arr);
}
// ...until ultimately the second-to-last value is copied onto the last value

// output:
// 0 => 2 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 2 )
// 1 => 4 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 4 )
// 2 => 6 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 6 )
// 3 => 6 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 6 )
?>

Example 5: php loop through array
