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
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));

Steps for approach 1:
1) You can first convert the string to array by explode() by comma(,).
You will get the following array:
Array
(
[0] => true // 1st true
[1] => true // 2nd true
[2] => true // 3rd true
[3] => false // 1st false
[4] => false // 2nd false
)
2) You will get an array containing 3 true and 2 false values (elements).
3) Then count how many times a values comes in array using array_count_values().
<?php
$var_from_loop = "true,true,true,false,false";
$arr = explode(',', $var_from_loop);
echo '<pre>';
print_r(array_count_values($arr));
echo '</pre>';
Output:
Array
(
[true] => 3
[false] => 2
)
Steps for approach 2 (only 3 lines of code):
You can even use substr_count():
$var_from_loop = "true,true,true,false,false";
echo 'TRUE: '.substr_count($var_from_loop, 'true');
echo '<br/>FALSE: '.substr_count($var_from_loop, 'false');
Output:
TRUE: 3
FALSE: 2
Use explode and array count function
$var_from_loop = "true,true,true,false,false";
print_r(array_count_values(explode(",",$var_from_loop)));
output:-
Array
(
[true] => 3
[false] => 2
)
