I need to know how to group and add array , but I'm not sure how to do it.
$array = array("vermelho", "vermelho", "vermelho", "verde", "azul", "azul");
I wanted a return like this
3
1
2
That is, it will group and add up the amount of equal items.
Example of array_count_values()
<?php
$array = array(1, "ola", 1, "mundo", "ola");
$a = array_count_values($array);
?>
or yours:
$array = array("vermelho", "vermelho", "vermelho", "verde", "azul", "azul");
$a = array_count_values($array);
var_dump($a);
The above example will print:
Array
(
[1] => 2
[ola] => 2
[mundo] => 1
)
'''
Alternative to the already mentioned array_count_values() :
$array = array("vermelho", "vermelho", "vermelho", "verde", "azul", "azul");
foreach ($array as $item) {
if(!isset($count[$item])) $count[$item] = 0;
$count[$item]++;
}
var_dump($count);
In this case, it gives the same result:
array(3) {
'vermelho' =>
int(3)
'verde' =>
int(1)
'azul' =>
int(2)
}
