PHP preg_split: Split string by forward slash

Question

I want to split my string 192.168.1.1/24 by forward slash using PHP function preg_split.

My variable :

$ip_address = "192.168.1.1/24";

I have tried :

preg_split("/\//", $ip_address); 
//And
preg_split("/[/]/", $ip_address); 

Error message : preg_split(): Delimiter must not be alphanumeric or backslash

I found the following answer here in stackoverflow Php preg_split for forwardslash?, but it not provide a direct answer.

Answer 1

Just use another symbol as delimiter

$ip_address = "192.168.1.1/24";

$var = preg_split("#/#", $ip_address); 

print_r($var);

will output

Array
(
    [0] => 192.168.1.1
    [1] => 24
)

Answer 2

This is another way that meet up your solution

$ip_address = "192.168.1.1/24";
$var = preg_split("/\//", $ip_address);
print_r($var);

Output result

Array(
    [0] => 192.168.1.1
    [1] => 24
)
