PHP - count specific array values (10 answers)

Closed 2 years ago.

Close my question when it ́sdifferent to this not duplicater, the case it ́s different in all : PHP - count specific array values My question not the same

I have this array for example :

$array_test=array("gren","green","red","red","green","blue");

My idea is know inside loop number of elementos with the condition i want, the array for show it ́s more complex and this is only example for understand i need, because try different ways with "count" and don ́t show right this number in each case.

I try this :

foreach($array_test as $array_ts) {
if($array_ts=="green") { Count number of elements green /// }
if($array_ts=="red") { Count number of elements red /// }
if($array_ts=="blue") { Count number of elements blue /// }
}

Thank ́s for the help, regards.

You can create an array and fill it with the count for each color:

$input = ["gren","green","red","red","green","blue"];
$count = [];
foreach ($input as $color) {
 if (array_key_exists($color, $count)) {
 $count[$color]++;
 } else {
 $count[$color] = 1;
 }
}

$count will contain:

["green"=>3, "red"=>2, "blue"=>1]

• user8034901: $input is not an array though
• Jean: No works, give me error
