I'm converting some shortcode information from an old CMS I'm using. In some article body text, I need to get the ID from some pre-existing callouts
{image id="27411" shape="landscape" align="right"}
There can be multiple callouts like this within one body of text. Is there a way to have this information returned as an array of IDs? The only important information is the ID, the rest is irrelevant.
If it's always in that format, use preg_match_all()
, like this:
preg_match_all( '#\{image id="(\d+)"[^\}]+\}#', $input, $matches);
Your array of IDs will be in $matches[1]
.
So, for your example input, this outputs:
array(1) {
[0]=>
string(5) "27411"
}
