array(
array(1,3,4),
array(
array(
1,2,3
)
)
),
array(
array(1,2),
array(1)
)

(PS: T is good PHP Q buckle: 276167802, verification: csl)
In fact, just the above answers should be sorted. Below Qingyuan shares a simple depth calculation function:
<?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;
}
$array = array( array("11"), array(),array( array(array("5", "6"), "7", "8")),array( array(array("5", "6"), "7", "8")), "9", "10");
echo array_depth($array);
