Array value from variable

Question

Could somebody explaind me ***why array count is not 2

$value = '"305", "112", ';
//remove last comma and space
echo $value = rtrim($value, ', ');
echo '<br>';

$value = array($value);

echo $array_length = count($value); //***

$value = array("305", "112"); so you will have two data in the array — Nobady

@treyBake I have this value in mysql column $value = '"305", "112", '; and I think that this is 2 elements, is possible make it two, why I said is two because if I pass it here $value = array($value); is two elements — chris

You should use explode function to get array like the following code :

$value = '"305", "112"'; 
        $value = rtrim($value, ', ');
        echo '<br>';
        $value = explode(',',$value); 
        echo $array_length = count($value);

you can use explode() to get it.

$value = '"305", "112", ';
//remove last comma and space
echo $value = rtrim($value, ', ');
echo '<br>';

$value = explode(',',$value);

echo $array_length = count($value);

Note you'll have two string values that contain double quotes surrounding each number in your array.

you can also do this if you want to create an array from that these type of strings and do array count.

$arr = array_filter(array_map('trim', str_getcsv($value)));
print_r($arr);
echo count($arr);

when you are creating an array with array($value), the entire value of $value counted as a single element of an array. Thats why you are getting count($value) not equal to 2.
