Create Search API like itunes Search API using PHP and MySQL

                      The Apple itunes provided a search API for retrieve app information from it. The Apple search API display result as JSON format. Do you want to know more information about Apple itunes search API, then visit iTunes Search API.

                      You can also create search API like Apple itunes search API if you know how to create JSON file using PHP. Due to this, you can provide search API for your websites. If you didn't know create JSON file using PHP and MySQL, then visit How to get output as JSON format using PHP and Mysql.

Generate Search API using PHP and MySQL

                       Lets see how to create search API using PHP.  Follow below steps to generate search API for your websites using PHP.

Step1: Connect MySQL database using PHP

                     Connect your MySQL database to get stored values from it using PHP. The PHP code for connect MySQL database is below:

 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('fitness') or die(mysql_error());

Step2: Get value from url using PHP

                     While user search something on your search API, you need to get those values for search from url. So only you can provide particular results from your MySQL database. This is done by below PHP code.


Step3: Make MySQL select query

                     After got values from url, you've to make MySQL query to select corresponding results from database. You can get zero or more than one values from urls for search. You should make MySQL query like below using PHP.

 if($field!='' && $limit!='')
   $cond="where name='".$field."' order by id desc limit 0, $limit";
 if($field=='' && $limit!='')
   $cond="order by id desc limit 0, $limit";
 if($field!='' && $limit=='')
   $cond="where name='".$field."' order by id desc limit 0, 50";
 if($field=='' && $limit=='')
   $cond="order by id desc limit 0, 50";
 $q=mysql_query("select * from f_img $cond") or die(mysql_error());

Step4: Add header for get output as JSON format

              You must add header type ato your PHP script for get output as JSON format. This is like below

 header('Content-Type: Application/json');

Step5: Add content to JSON file using PHP

               You need to create 2 array for create output as multidimensional array. Retrieve values from query result using mysql_fetch_arrayThen you push values to array using array_push() in PHP. Finally encode the results to display output as JSON format using json_encode().

               The full PHP code for create search API is represented below,

 error_reporting('E_ALL ^ E_NOTICE');
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('fitness') or die(mysql_error());
 if($field!='' && $limit!='')
   $cond="where name='".$field."' order by id desc limit 0, $limit";
 if($field=='' && $limit!='')
   $cond="order by id desc limit 0, $limit";
 if($field!='' && $limit=='')
   $cond="where name='".$field."' order by id desc limit 0, 50";
 if($field=='' && $limit=='')
   $cond="order by id desc limit 0, 50";
 $q=mysql_query("select * from user $cond") or die(mysql_error());
 header('Content-Type: Application/json');
 echo json_encode($details);


           Your JSON output should be like below,

 {"name":"Anderson","state":"Los Angeles","country":"USA"},
 {"name":"Smith","state":"London","country":"United Kingdom"},
 {"name":"Jones","state":"Cambridge","country":"United Kingdom"},
 {"name":"Nathan","state":"Franche Comte","country":"France"},
 {"name":"Nastya","state":"St Petersburg ","country":"Russia"},
 {"name":"Hoang","state":"Hai Phong","country":"vietnam"},

Step6 : .htaccess

                   Add following lines to your .htaccess file

RewriteRule ^search search.php [L]

                  Now you entered search on address bar, the .htaccess redirects you to search.php file. You can get search API using below url types.

<?xml version='1.0' encoding='UTF-8'?>
<rss version='2.0'>

      <description>Htaccess doubts clarified at Phponwebsites</description>

Generate RSS Feed dynamically using PHP and MySQL

                 Let see how to create RSS Feed dynamically using PHP and MySQL. Follow the below steps to create feed.

1. Create database and table

                  First you create database for store your link details on it. The below MySQL query is used for create database.

                Create database new

 where new is database name

                Use new

The above query is used to use database "new".
                  The MySQL query for create table is,

                Create table links (id int not null auto_increment primary key, name varchar(200), link varchar(200), description varchar(250))

                 Now the table "links" is created. Then store values into table using below query

                insert into table links values('','PHP','','PHP doubts are clarified at Phponwebsites')

                After insert values into table, your table look likes below

insert values into MySQL table for RSS Feed

2. Add header type RSS Feed

                            First you need to add content type of RSS feed. It is represented below.

header("Content-Type: application/rss+xml; charset=ISO-8859-1");

3. Add content to RSS Feed

                            First of all you need to store all links in your database. Then on;y you can retrieve it using PHP. The below example we Retrieve data from MySQL database using mysql_fetch_array in PHP.
After added header, you have to add some name spaces for RSS Feed. Finally add contents to RSS Feed.

header("Content-Type: application/rss+xml; charset=ISO-8859-1");
echo '<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" media="screen" href="/~d/styles/rss2full.xsl"?>
<?xml-stylesheet type="text/css" media="screen" href=""?>
<description>Phponwebsites about php related topics like .htaccess, robots.txt, mysql, jquery, ajax, js and also php for php developers</description>';
       $connection = @mysql_connect('localhost', 'root', '') or die(mysql_error());
       mysql_select_db('new')  or die (mysql_error());
       $query = "SELECT * FROM links order by id desc";
       $rss = mysql_query($query) or die (mysql_error());
       echo '
      <![CDATA[<p align="left">
          <a href="'.$row['link'].'"><img style="background-image: none; " border="0" src="'.$ImgPath.'" />    </a></p>]]>
      echo '</channel>

               When you run this file on firfox, you will get output like below

Create RSS Feed dynamicall using PHP and MySQL

4. Htaccess

                         Then you have to add below lines to your htaccess file.

                    RewriteRule ^rss.xml$ rss.php [L]

When you type rss.xml in your browser address bar, it redirects to rss.php.

             Finally you got dynamic RSS Feed.
