从PHP的Instagram标题中删除表情符号

Question

Does anyone know to strip the emoticons from instagram captions? I subscribe to their api for feeding certain photo types and display them on my website. I tried used the command below in PHP to strip out emoticons with no success.

    $newcaption  = preg_replace('/[^a-zA-Z0-9 \.]/s', '', $caption);

Does anyone know how to get rid of instagram emoticons using PHP? I have no idea what their ascii character set is.

Answer 1

Instagram does not have native emoticons. My suggestion is, create an array with all known emoticons (emoji, Android, iOS, etc) and than search and remove them from the $caption.

I don't see other way to do it.

Update:

I have written a regex that could help you without creating the array, but it can lead into some mistakes. Try and watch the results, here it is:

$pattern = '/((?=:)|(?=;))(.*)(?=\s{1,})/i';
preg_replace($pattern, '', $string);
