A quick way to determine the depth of a PHP multidimensional array _php tips

For example, there is a multidimensional array:

Copy Code code as follows:

Array
Array
Array (1,3,4),
Array
Array
1,2,3
)
)
),
Array
Array (1,2),
Array (1)
)
)

The depth of this array is 5, so how quickly to determine the depth of an array.

(Ps:t good PHP Q-buckle 峮: 276167802, Validation: CSL)

In fact, just the answers above should be sorted again. Below the Qingyuan share a simple computational depth function:

Copy Code code as follows:

<?php
function Array_depth ($array) {
$max _depth = 1;


foreach ($array as $value) {
if (Is_array ($value)) {
$depth = array_depth ($value) + 1;


if ($depth > $max _depth) {
$max _depth = $depth;
}
}
}
return $max _depth;
}

$array = Array (Array ("one"), array (), Array (Array ("5", "6"), "7", "8"), Array (Array ("5", "6"), "7", "8"), "9 "," 10 ");
echo array_depth ($array);
?>
