if i use $tes = explode("]", $content); the "]" is lost

Solution

  • Instead of splitting, you could also match the parts that you want by matching optional horizontal whitespace chars, and then capture in group 1 as least as possible chars followed by matching [...]

    For the matches get the group 1 value using $matches[1]

    \h*(.*?\[[^][]*])

    Example code

    $s = "i want to show you my youtube channel : [youtube id=12341234] and my instagram account : [instagram id=myingaccount213]";
preg_match_all("~\h*(.*?\[[^][]*])~", $s, $matches);
print_r($matches[1]);

    Output

    Array
(
    [0] => i want to show you my youtube channel : [youtube id=12341234]
    [1] => and my instagram account : [instagram id=myingaccount213]
)

    Another option is making the pattern a bit more specific for youtube or instagram:

    \h*(.*?\[(?:youtube|instagram)\h+id=[^][\s]+])
