How to split a string by commas in PHP

Question

I am a beginner with PHP and I would like to know how can I get the parts x, y, z, and t of a sequence of characters which has the form "x, y, z, t":

Example:

$str1 = "2,161,0,0"; 
$str2 = "2,3,10,4";

for $str1 we have to recover:

2 -> x

161 -> y

0 -> z

0 -> t

@RobbieAverill oh yeah you’re right, with the original title they’d have a hard time finding anything. — misorude, Oct 15 '18 at 11:14

Try this:

explode(',', $str1);

Since you need the string components as separate variables, which is well, weird, you also need to make use of list as well:

list($x, $y, $z, $t) = explode(',', $str1);

Or using the short list syntax since PHP 7.1:

[$x, $y, $z, $t] = explode(',', $str1);

You can follow this example:

$str1 = "2,161,0,0"; 

$array = explode(',', $str1);
print_r($array);

Output will then be:

array
(
    [0] => 2
    [1] => 161
    [2] => 0
    [3] => 0
)
