here is google keyword suggestion code

	$q = strtolower($_GET["q"]);
	if (!$q) return;
	$len = strlen($q);
	$limit = isset($_GET['limit']) ? (int) $_GET['limit'] : 0;


$aResults = array();
$count = 0; $i=0;

  $url = "http://suggestqueries.google.com/complete/search?qu=" . $q;

$text = file_get_contents($url); 
$text = str_replace('window.google.ac.h(["' . $q . '",[[', '', $text);
$arr_items = explode('],[', $text);


foreach($arr_items as $items) {           
    $arr_item = explode(',', $items);
    $key = $arr_item[0];
    $key = trim($key, '"');

    if (strpos(strtolower($key), $q) !== false) {

			$count++;
			$aResults[] = array( "id"=>($i+1) ,"value"=>htmlspecialchars($key) );
		}

here is full code of my php

<?php


$q = strtolower($_GET["q"]);
if (!$q) return;
$len = strlen($q);
$limit = isset($_GET['limit']) ? (int) $_GET['limit'] : 0;


$aResults = array();
$count = 0; $i=0;

$url = "http://suggestqueries.google.com/complete/search?qu=" . $q;

$text = file_get_contents($url); 
$text = str_replace('window.google.ac.h(["' . $q . '",[[', '', $text);
$arr_items = explode('],[', $text);


foreach($arr_items as $items) {           
    $arr_item = explode(',', $items);
    $key = $arr_item[0];
    $key = trim($key, '"');

    if (strpos(strtolower($key), $q) !== false) {

			$count++;
			$aResults[] = array( "id"=>($i+1) ,"value"=>htmlspecialchars($key) );
		}



		if ($limit && $count==$limit)
			break;
		$i++;		
}
/*	if ($len)
	{
		for ($i=0;$i<count($aUsers);$i++)
		{
			// had to use utf_decode, here
			// not necessary if the results are coming from mysql
			//
			if (strtolower(substr(utf8_decode($aUsers[$i]),0,$len)) == $q)
			{
				$count++;
				$aResults[] = array( "id"=>($i+1) ,"value"=>htmlspecialchars($aUsers[$i]), "info"=>htmlspecialchars($aInfo[$i]) );
			}

		if ($limit && $count==$limit)
			break;
	}
