在模式REGEX之后爆炸POST变量

Question

I'm terrible at regex, hard to understand for me so I need some help. I have a variable which looks something like this:

["data:image/png;base64,Ivksfk...=", "data:image/png;base64,JksdkJkf...=", "data:image/png;base64,okKJjfeiw...="]

Those are 3 values which I want to split into an array. The way I see it, I want to split it at the comma which comes after a quote ", ". Can someone please help me with the regex for preg_split?

Answer 1

You could try the below code to split the input string according to ", "

<?php
$yourstring = '["data:image/png;base64,Ivksfk...=", "data:image/png;base64,JksdkJkf...=", "data:image/png;base64,okKJjfeiw...="]';
$regex = '~", "~';
$splits = preg_split($regex, $yourstring);
print_r($splits);
?>

Output:

Array
(
    [0] => ["data:image/png;base64,Ivksfk...=
    [1] => data:image/png;base64,JksdkJkf...=
    [2] => data:image/png;base64,okKJjfeiw...="]
)

If you don't want "[,]" in the output then you could try the below code.

<?php
$data = '["data:image/png;base64,Ivksfk...=", "data:image/png;base64,JksdkJkf...=", "data:image/png;base64,okKJjfeiw...="]';
$regex =  '~(?<=\["|", ")[^"]*~';
preg_match_all($regex, $data, $matches);
print_r($matches);
?>

Output:

Array
(
    [0] => Array
        (
            [0] => data:image/png;base64,Ivksfk...=
            [1] => data:image/png;base64,JksdkJkf...=
            [2] => data:image/png;base64,okKJjfeiw...=
        )
