Just a _SELF_ reminder for this function that is pretty useful sometimes.

phpAlertJS.php

<?php
function php_alert($message){
  echo "<script type='text/javascript'>!function(){ alert('". $message . "');}()</script>";
}

//example
...
$result = mysqli_query($someconnection, "SELECT * FROM table");

if(!$result){
  php_alert('No result. Damn!');
}else{
  ...
}

?>
