Getting the data - PHP

Based on the previous section's analysis of PHP code, you can easily grab important data. For example, say you need the title tag of all backlink URLs.

Let:

$display= $unserialized ['ResultSet'];

$display1=$display['Result'];

This is the command to penetrate from the outermost array to the results array, and then, by the properties of combinational array, the title tag can be called as:

$display1[$x]['Title'];

Where $x is the counter of the array (example: 0 for the first back link, and 2 for the third back link.)

The final PHP code required to make a request to the Yahoo API, grab the response and finally display the title tag of all back link URLs to the browser is as follows:

<?php

//Step 1. Report possible errors for debugging

error_reporting(E_ALL);

//Step 2. Declare the request variable

$request='http://search.yahooapis.com/SiteExplorerService/V1/inlinkData?appid= TrnTAC3V34FlhDKeOScqpmw42Tu8B4BI8VUI7awsdcvfYIjJDwbtnb4rfNmmeQ--&query=http://www.php-developer.org&results=3&output=php';

//Step 3. Read the responses from Yahoo inbound links API and put into a string.

$response = file_get_contents($request);

//Step 4

if ($response === false) {

die('The request fails.');

}

//Step 5. Convert to unserialized

$unserialized = unserialize($response);

//Step 6. To display the array in the browser:

echo '<pre>';

print_r($unserialized);

echo '</pre>';

echo '<br />';

//DISPLAY THE TITLE TAG OF ALL BACKLINK URL

$display= $unserialized['ResultSet'];

$display1=$display['Result'];

//$display2=$display1[0]['Title'];

$x=0;

$count= sizeof($display1);

//echo $count;

while ($x < $count) {

echo $display1[$x]['Title'];

echo '<br />';

$x++;

}

?>

Take note that the WHILE loop has been used to iterate the grabbing of data from the first back links with array [0] to the maximum size of the array, determined by the sizeof() function.
