Multiple Select HTML Form Fields PHP Parse Tutorial

Here we instruct how to use PHP to parse multiple selection form fields in your HTML or HTML5 forms. The resulting variable is an array if you instruct the select field to handle multiple options. We have to break this array down to split the selections for our data processing needs, or you can choose to save the serialized complete array into one MySQL database field.

<?php

if(isset($_POST['skills'])){
	$skillsArray = $_POST['skills'];
	// echo $skillsArray; // Echos the "Array" object
	$i = 0;
	foreach ($skillsArray as $key => $value) { 
        $i++;
        echo "Skill $i || Array Key = $key || Value = $value<br />"; 
    }
	exit();
}
?>
