将dataURI图像从JavaScript解析为PHP

Question

I created a function in JavaScript that transform an 'image' file selected by user to dataURI. Then I passed it to a php script by POST method. The problem is when I try to save this information into MySQL as follows

$him = $_POST["him"];
$req = $pdo->prepare("INSERT INTO `cr`.`chercheur` 
                    (`cin`, `nom`, `prenom`, `statut`, 
                     `tel1`,  `email`, `tof`, `etat`) 
                VALUES (?, ?, ?, ?, ?,?, ?, '0')");
$req->execute(array($cin,$nom,$prenom,$statu,$tel,$mail,$him));

I get an error below.

Warning: PDOStatement::execute(): MySQL server has gone away in C:\Program Files (x86)\EasyPHP-DevServer-14.1VC9\data\localweb\projects\CR\module\compte\demande\dem_user.php on line 89

Answer 1

The problem is that dataURI in JavaScript side use the "+" to concat and PHP use "." so the solution is to substitue "+" to "."
