Get also non-matching strings from preg_match_all - php

Question

I have some text with <img> tags in is that I need to divvy up. It's in the format
<img.../> Text text text <img.../>text text text<img.../> text text text
I have my regex qworking in preg_match_all so that I get
Array
(
[0] => Array
(
[0] => <img ... />
[1] => <img ... />
[2] => <img ... />
[3] => <img ... />
)
But it would be really nice if I could get
Array
(
[0] => Array
(
[0] => <img ... />
[1] => text text text
[2] => <img ... />
[3] => text text text
[4] => <img ... />
[5] => text text text
)
I've tried a few things but I really don't have a good understanding of PCREs. I don't want to use preg_split if I can avoid it because each of the images tags are different.
(I understand that a general HTML parser cannot be written with regular expressions, but in this case, I think this will work because the input data that I'm working is in the form I described. There aren't going to be any nested image tags that I'll need to worry about.)
PS I've tried /!<img.+>/, /!(<img.+>)/, and /(!(<img.+>))/ to get the non-matches, but it returns an empty array. I don't know a good way to debug regexes to know what I'm doing wrong.

Answer 1

I don't know what your issue (or actual code for that matter) is, but:
$r = preg_split('#<img[^>]+>#', $source, 0, PREG_SPLIT_DELIM_CAPTURE);
results in:
Array
(
[0] => <img.../>
[1] => Text text text
[2] => <img.../>
[3] => text text text
[4] => <img.../>
[5] => text text text
)
In place of a proper regex, you can keep using your fixed strings (I presume) with #<img1>|<img2>|<img3># of course.

Answer 2

You can have the information you want just not quite in the right format by doing this:
preg_match_all('~(<img[^>]*>)([^<]+)~', $str, $matches);
//if inside your "text text text" areas you have other html tags, use this:
preg_match_all('~(<img[^>]*>)(.+?)(?=<img|$)~', $str, $matches);
At this point, $matches[0] contains the entire matched string. $matches[1] contains all of the matches from the first set of parenthesis and $matches[2] contains all of the matches from the second set of parenthesis.
Array (
[0] => Array (
[0] => <img.../> Text text text
[1] => <img.../>text text text
[2] => <img.../> text text text
)
[1] => Array (
[0] => <img.../>
[1] => <img.../>
[2] => <img.../>
)
[2] => Array (
[0] => Text text text
[1] => text text text
[2] => text text text
)
)
Now if you really need it formatted the way you would like, just add these lines of code:
$answer = array();
foreach($matches[0] as $i=>$match){
$answer[] = $matches[1][$i];
$answer[] = $matches[2][$i];
};
$answer now looks like this:
Array (
[0] => <img ... />
[1] => Text text text
[2] => <img ... />
[3] => text text text
[4] => <img ... />
[5] => text text text
)
