Contents |
Description
Counts all the values of an array.
Returns an array using the values of the input array as keys and their frequency in input as values.
Parameters

The array to use.
Return Value
Success: new array
Failure: empty array
Remarks

Example
$array = array(1, "hello", 1, "world", "hello"); printr(CountValues($array)); /* // Prints ARRAY { [1] => 2 [hello] => 2 [world] => 1 } */
Here is an example with one or more arrays, which have similar values in it: Use $lower = true/false to ignore/set case sensitivity.
$res = iCountValues ($ar1); printr($res); function iCountValues($arr, $lower = true) { $arr2 = array(); if($arr['0'] !~ Array) $arr = array($arr); foreach($arr as $k => $v) @{ foreach($v as $v2) @{ if($lower == true) $v2 = lc($v2); if(!IsIndexSet($arr2, $v2)) $arr2[$v2] = 1; else $arr2[$v2]++; } } return $arr2; } /* // Prints ARRAY { [red] => 3 [green] => 3 [yellow] => 4 [blue] => 2 [brown] => 2 [white] => 1 [black] => 1 } */
