javascript -serialize a js arrary into a php array

phpfreakjav · July 3, 2009

I just wanted to share this code because it took me a while to figure howto do this.

<html>
<head>
	<script  language="Javascript">
//alternative 1
			function php_serialize(obj)
							{
								var string = '';

								if (typeof(obj) == 'object') {
									if (obj instanceof Array) {
										string = 'a:';
										tmpstring = '';
										count = 0;
										for (var key in obj) {
											tmpstring += php_serialize(key);
											tmpstring += php_serialize(obj[key]);
											count++;
										}
										string += count + ':{';
										string += tmpstring;
										string += '}';
									} else if (obj instanceof Object) {
										classname = obj.toString();

										if (classname == '[object Object]') {
											classname = 'StdClass';
										}

										string = 'O:' + classname.length + ':"' + classname + '":';
										tmpstring = '';
										count = 0;
										for (var key in obj) {
											tmpstring += php_serialize(key);
											if (obj[key]) {
												tmpstring += php_serialize(obj[key]);
											} else {
												tmpstring += php_serialize('');
											}
											count++;
										}
										string += count + ':{' + tmpstring + '}';
									}
								} else {
									switch (typeof(obj)) {
										case 'number':
											if (obj - Math.floor(obj) != 0) {
												string += 'd:' + obj + ';';
											} else {
												string += 'i:' + obj + ';';
											}
											break;
										case 'string':
											string += 's:' + obj.length + ':"' + obj + '";';
											break;
										case 'boolean':
											if (obj) {
												string += 'b:1;';
											} else {
												string += 'b:0;';
											}
											break;
									}
								}

								return string;
			}

			function displayArray(x)
							{//only displays 1 dimensional array
								for (i=0;i<x.length;i++)
									{
										document.write(x[i] + "<br >");
									}
			}
//alternative 2
			function js_array_to_php_array (a)
			// This converts a javascript array to a string in PHP serialized format.
			// This is useful for passing arrays to PHP. On the PHP side you can
			// unserialize this string from a cookie or request variable. For example,
			// assuming you used javascript to set a cookie called "php_array"
			// to the value of a javascript array then you can restore the cookie
			// from PHP like this:
			//    <?php
			//    session_start();
			//    $my_array = unserialize(urldecode(stripslashes($_COOKIE['php_array'])));
			//    print_r ($my_array);
			//    ?>
			// This automatically converts both keys and values to strings.
			// The return string is not URL escaped, so you must call the
			// Javascript "escape()" function before you pass this string to PHP.
			{
			    var a_php = "";
			    var total = 0;
			    for (var key in a)
			    {
			        ++ total;
			        a_php = a_php + "s:" +
			                String(key).length + ":\"" + String(key) + "\";s:" +
			                String(a[key]).length + ":\"" + String(a[key]) + "\";";
			    }
			    a_php = "a:" + total + ":{" + a_php + "}";
			    return a_php;
			}



			var x = new Array("1","2");
			var x1=new Array();
			x1=x;
			displayArray(x);
			displayArray(x1);
			document.write("Serializing starts <br/>");
			x=php_serialize(x);
			displayArray(x);

			document.write("Serializing starts <br/>");
			x1=js_array_to_php_array(x);
			displayArray(x1);
			escape();
