Array function

[abch624]

Hi guys a quick one...

 

I have an array with strings in it and I would like to get out the number of times on string has been repeated in the array....

 

foreach ($tags as $key => $value) {
    
}

 

I would like to know how many time this "$key" has been repeated in the array.

 

Please help

You can use:

 

$counts = array_count_values(array_keys($tags));

 

The values of $counts will correspond to the frequency of the key of the array, which corresponds to the keys of the first array.

na that didnt work just gives me one for all

 

Array ( [0] => 1 [1] => 1 [2] => 1 [3] => 1 [4] => 1 [5] => 1 [6] => 1 [7] => 1 [8] => 1 [9] => 1 [10] => 1 [11] => 1 [12] => 1 [13] => 1 [14] => 1 [15] => 1 [16] => 1 [17] => 1 [18] => 1 [19] => 1 )

A key value can only occur once in an array

WOW, I didn't think of that.  Good catch, Barand.

If array keys could appear more than once, my code would have worked, lol.  Do you want the counts of duplicate array VALUES?

Yes I said repeated strings lol

help guys

as Barand helpfully pointed out:

Maybe you want repeated values.

$array = array("apple" => "green",
                    "apple" => "red",
                    "strawberry" => "red"
             );

Are you trying to see how many times apple is in the array, or red?

apple = key

red = value

try

<?php
$tags = array ('A', 'B', 'A', 'C', 'D', 'B', 'A', 'C', 'A', 'C', 'D', 'E');

$tagCounts = array_count_values($tags);

foreach ($tags as $k => $v)
{
echo "$k : $v (occurs {$tagCounts[$v]} times)<br/>";
}
?>

-->
0 : A (occurs 4 times)
1 : B (occurs 2 times)
2 : A (occurs 4 times)
3 : C (occurs 3 times)
4 : D (occurs 2 times)
5 : B (occurs 2 times)
6 : A (occurs 4 times)
7 : C (occurs 3 times)
8 : A (occurs 4 times)
9 : C (occurs 3 times)
10 : D (occurs 2 times)
11 : E (occurs 1 times)
