Some time spent to try but now i think it works:
<?php
echo "<pre>";
$a='datadatadatadata[link1]datadatadata{link2}data[link3]';
// $a='datadata{link1}data[link2]datadatadata{link3}data[link4]';
$pattern='/((\[)|\{)(.+?)(?(2)\]|\})/';
echo $a."\n";
echo $pattern."\n";
preg_match_all($pattern,$a,$matches,PREG_MATCH_ORDER);
var_dump($matches);
?>
Produces :
<pre>datadatadatadata[link1]datadatadata{link2}data[link3]
/(\[)|\{(.+?)(?(1)\]|\})/
array(3) {
[0]=>
array(3) {
[0]=>
string(1) "["
[1]=>
string(7) "{link2}"
[2]=>
string(1) "["
}
[1]=>
array(3) {
[0]=>
string(1) "["
[1]=>
string(0) ""
[2]=>
string(1) "["
}
[2]=>
array(1) {
[0]=>
string(5) "link2"
}
}
Also works with the commented string.
Explanation : Looking for more than one using preg_match_all. Matching for [ or {, [
is in () because at the end we test if we found
[ so we look for ] otherwise { is found so we look for matching }. (?(1) true|false)
is 1 as a backreference is set so we found [.
Hope this will help you.
