note 93764 added to function.print-r

Here's an array_depth() function that calculates the depth of an array using the indentation in the output of print_r(): <?php function array_depth($array) { $max_indentation = 1; $array_str = print_r($array, true); $lines = explode("\n", $array_str); foreach ($lines as $line) { $indentation = (strlen($line) - strlen(ltrim($line))) / 4; if ($indentation > $max_indentation) { $max_indentation = $indentation; } } return ceil(($max_indentation - 1) / 2) + 1; } ?> It's better than writing a recursive function to do the same thing, as print_r() handles the problem of infinitely-deep arrays for you quite nicely. ---- Server IP: 72.55.140.6 Probable Submitter: 71.17.240.44 ---- Manual Page -- http://www.php.net/manual/en/function.print-r.php Edit -- https://master.php.net/note/edit/93764 Del: integrated -- https://master.php.net/note/delete/93764/integrated Del: useless -- https://master.php.net/note/delete/93764/useless Del: bad code -- https://master.php.net/note/delete/93764/bad+code Del: spam -- https://master.php.net/note/delete/93764/spam Del: non-english -- https://master.php.net/note/delete/93764/non-english Del: in docs -- https://master.php.net/note/delete/93764/in+docs Del: other reasons-- https://master.php.net/note/delete/93764 Reject -- https://master.php.net/note/reject/93764 Search -- https://master.php.net/manage/user-notes.php
