blindcoder, 
Just spent TWO HOURS debugging PHP code because I relied on my IDE and github Copilot which both didn't catch the bug in the code below:
<?php
if (array_key_exists("error", $response){
$return_value = [];
}
?>Error message was: PHP Parse error: syntax error, unexpected token ";" in <file> on line 3
Yes, it's on me, but I'm supposed to test this tech for my employer and results are not looking favorably.
Edit: added proper line number for my example
