我想从循环中创建数组并从该数组中计算相同的值

Question

I want create array from looping.

I have tried using array_count_values() for count the array element, but variable from looping not read as array.

it's my code

$var_from_loop = "true,true,true,false,false";

I expect the output of:

true = 3
false = 2

Answer 1

Use explode (doc) to convert the string to array by , and then use array-count-values:

$var_from_loop = "true,true,true,false,false";
$arr = explode("," , $var_from_loop);
print_r(array_count_values($arr));
