Question

First, I am not very good in regex so there may be a mistake in here. I got the following regex pattern I created :

`(?:\\&|[^&])*` (PHP : `/(?:\\&|[^&])*/s`) 

to parse the kind of the following string :

hfghfg=hfghfg&gfdgdf=4343543&gfdgfdgfd=fsdfds\&hghg999

Espresso give me this :

hfghfg=hfghfg
NULL
gfdgdf=4343543
NULL
gfdgfdgfd=fsdfds\&hghg999
NULL

So it does the same as explode('&', $String) but if \& is found, it won’t cut.

But in PHP, preg_match_all and preg_match give me this :

preg_match_all('/(?:\\&|[^&])*/s', 
                     implode('', $this->Grecko->Input->Server('argv')), 
                     $Args, PREG_PATTERN_ORDER);
print_r($Args);

Array
(
    [0] => Array
        (
            [0] => hfghfg=hfghfg&gfdgdf=4343543&gfdgfdgfd=fsdfds\&hghg999
            [1] => 
        )

)

Answer 1

I think what you need is preg_split() rather than preg_match_all().

$str = 'hfghfg=hfghfg&gfdgdf=4343543&gfdgfdgfd=fsdfds\&hghg999';
$res = preg_split('/(?<!\\\)&/', $str);

print_r($res);

/*
Array
(
  [0] => hfghfg=hfghfg
  [1] => gfdgdf=4343543
  [2] => gfdgfdgfd=fsdfds\&hghg999
)
