note 37987 added to function.count-chars

Here is a simple item frequency counter function, useful in reporting or statistical apps: <?php function count_item(&$freq, $item, $inc = 1) { if (! is_array($freq)) { $freq = array (); } $freq[$item] = (isset($freq[$item]) ? ($freq[$item] += $inc) : $inc); return true; } ?> This function saves you the hassle of doing the isset() check each time you wish to increase the frequency. If you're not normally concerned over PHP's warnings about uninitialized variables, then you should probably start from the beginning. If you are, use the function above like: <?php count_item($freq, 'foo'); count_item($freq, 'bar'); count_item($freq, 'foo'); ?> After this, $freq will equal array ('foo' => 2, 'bar' => 1) ---- Manual Page -- http://www.php.net/manual/en/function.count-chars.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+37987 Delete -- http://master.php.net/manage/user-notes.php?action=delete+37987&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+37987&report=yes Search -- http://master.php.net/manage/user-notes.php
