Insert Your Recent Comments from Facebook to Database

The sample is for scraping data from Facebook home page. Once you will pass your username and password in variables  i have declared in file and execute the code you will get your home page of Facebook.

Here php code will pass the variables by POST method to page and login into facebook account then other curl call will call my home page to get the home page HTML.

I have written code of how i am scrapping data by DOM Parser.

$first_name = 'First Name';
$login_email = 'facebookloginemail';
$login_pass = 'password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, '');
curl_setopt($ch, CURLOPT_POSTFIELDS,'email='.urlencode($login_email).'&pass='.urlencode($login_pass).'&login=Login');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_COOKIEJAR, "my_cookies.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "my_cookies.txt");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20070309 Firefox/");

curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_URL, '');
$page = curl_exec($ch);

Here it will print the facebook home page with your recent updates

echo $page;

// Parse the HTML information and return the results.
$dom = new DOMDocument();

$xpath = new DOMXPath($dom);

// Get a list of articles from the section page

$articleList = $xpath->query("*/div[@id='m_stream_stories']");

// Add each articles url to the Articles array
// This way we can scrap any part of data of any sites.

$articles = array();
foreach ($articleList as $item){
	$articles[] = array(
								'url' => $item->getElementsByTagName('a')->item(0)->getAttribute('href')


// Here we can loop for the article array and insert it into database.

Uploading file by PHP Code

Let’s start by creating the html file form:

Files are uploaded from the browser using an input tag, with the type parameter set to “file”. This is supported by all browsers currently available on the market.

The most important thing is to set the ENCTYPE attribute of the form to “multipart/form-data” and set the form’s action to the file upload page. The file upload page will handle the actual file uploading.
html file : upload.html

 <form name="frmupload" id="frmupload" method="post" action="/upload.php" enctype="multipart/form-data">
  <legend>File upload:</legend>
	  <label for="file">File:</label>
	  <input name="vFile" type="file" id="vFile" />
  <input type="submit" name="upload" value="Upload" />

Now first create the upload script:
In PHP, uploaded files are accessed via the $_FILES array:

* $_FILES["file"]["name"]: The original filename on the client’s machine.
* $_FILES['file']['type']: The mime type of the file.
* $_FILES['file']['size']: The size, in bytes, of the uploaded file.
* $_FILES['file']['tmp_name']: The temporary filename of the file in which the uploaded file was stored on the server.

Here i have created one function so we will call this in our upload.php it will makes easy to upload , optimize the code and make the code reusable.

php script file : upload.php

$imagepath='';		// Make Sure you have set the permission of folder in which you are uploading files.
$image= $_FILES['file']['tmp_name'];
$image_name= $_FILES['file']['name'];
$prefix=''; 	// Optional
$vaildext= "gif,jpg,jpeg,bmp,PNG,JPG,JPEG,GIF,BMP,png"; 

$output = fileupload($imagepath , $image , $image_name , $prefix , $vaildext);

fileupload($imagepath,$image,$image_name,$prefix='', $vaildExt= "gif,jpg,jpeg,bmp,PNG,JPG,JPEG,GIF,BMP,png");
 function fileupload($imagepath,$image,$image_name,$prefix='', $vaildext= "gif,jpg,jpeg,bmp,PNG,JPG,JPEG,GIF,BMP,png")

	   if(!empty($image_name) and is_file($image) )

			$vaildext_arr = explode(",", strtoupper($vaildext));
			if(in_array(strtoupper($ext), $vaildext_arr))
				$ftppath1 = $imagepath.$imagefile;
				if(!copy($image, $ftppath1))
					$imagefile = '';
					$msg="Failed to Upload files !!";
					$msg="File uploaded successfully !!";
				$imagefile = '';
				$msg="Extension Is Not Valid, please use mentioned extesions only $vaildExt !!!";
		$ret[0] = $imagefile;
		$ret[1] = $msg;
		return $ret;

Its easy and working :)

Let me know your thoughts if you are facing any problem while uploading files.

PHP Functions to Import/Export CSV data

These two function make it very easy to import and export CSV in PHP.

This function has just one argument – the query that returns the necessary data to be exported.

Example: CSVExport(“SELECT name,username,email,url FROM User WHERE status=1″);

This will upload a CSV file and import the data into the specified table. This function must have the following arguments…

The name of the table the data must be imported to
An array of fields that will be used
The name of the CSV file field

Example: CSVImport(“User”, array(‘name’,'username’,'email’,'url’), “csv_file”);
//Get the result of the query as a CSV stream.
function CSVExport($query) {
$sql_csv = mysql_query($query) or die(“Error: ” . mysql_error()); //Replace this line with what is appropriate for your DB abstraction layer

while($row = mysql_fetch_row($sql_csv)) {
print ‘”‘ . stripslashes(implode(‘”,”‘,$row)) . “\”\n”;

//Import the contents of a CSV file after uploading it
//Aruguments : $table – The name of the table the data must be imported to
// $fields – An array of fields that will be used
// $csv_fieldname – The name of the CSV file field
function CSVImport($table, $fields, $csv_fieldname=’csv’) {
if(!$_FILES[$csv_fieldname]['name']) return;

$handle = fopen($_FILES[$csv_fieldname]['tmp_name'],’r');
if(!$handle) die(‘Cannot open uploaded file.’);

$row_count = 0;
$sql_query = “INSERT INTO $table(“. implode(‘,’,$fields) .”) VALUES(“;

$rows = array();

//Read the file as csv
while (($data = fgetcsv($handle, 1000, “,”)) !== FALSE) {
foreach($data as $key=>$value) {
$data[$key] = “‘” . addslashes($value) . “‘”;
$rows[] = implode(“,”,$data);
$sql_query .= implode(“),(“, $rows);
$sql_query .= “)”;

if(count($rows)) { //If some recores were found,
//Replace these line with what is appropriate for your DB abstraction layer
mysql_query(“TRUNCATE TABLE $table”) or die(“MySQL Error: ” . mysql_error()); //Delete the existing records
mysql_query($sql_query) or die(“MySQL Error: ” . mysql_error()); // and insert the new ones.

print ‘Successfully imported ‘.$row_count.’ record(s)’;
} else {
print ‘Cannot import data – no records found.’;

Using PHP Short Tags

PHP Short Tags refers to ‘

Short tags are considered bad because they are in conflict with XML’s open tag – ‘

This problem can be solved easily – I use this code…


I use the full tag almost all the time. The only exception is that I use . And I am not prepared to give that up.

I follow the MVC pattern in my projects. My PHP framework, iFrame, is an MVC framework. In the template(view) part, there is a lot of usage of such tags. It is more concise and more readable than the alternative…

You tell me – which is better?

I hear that they will be introducing in PHP 6. Until then, I will continue to use .

Convert PHP arrays to JSON

While we are working with json arrays or calling ajax files that return json in their response sometime we stuck for making json array.
This is because the json array is quite difficult to maintain. You must have to take care of each every special character that is really very difficult if you are thinking to do it manually like “CDATA” for xml.
The best solution that i got from “” is to just make array of PHP and convert it into JSON by using user defined PHP function.


First you need a PHP array. For example…

$data = array(
‘success’ => “Sweet”,
‘failure’ => false,
‘array’ => array(),
‘numbers’ => array(1,2,3),
‘info’ => array(
‘name’ => ‘Binny’,
‘site’ => ‘’

Provide this array as the argument of the array2json() function…

$json = array2json($data);

The resulting string will be(actual output – the source says print array2json($data);)…


function array2json($arr) {
if(function_exists(‘json_encode’)) return json_encode($arr); //Lastest versions of PHP already has this functionality.
$parts = array();
$is_list = false;

//Find out if the given array is a numerical array
$keys = array_keys($arr);
$max_length = count($arr)-1;
if(($keys[0] == 0) and ($keys[$max_length] == $max_length)) {//See if the first key is 0 and last key is length – 1
$is_list = true;
for($i=0; $i
if($i != $keys[$i]) { //A key fails at position check.
$is_list = false; //It is an associative array.

foreach($arr as $key=>$value) {
if(is_array($value)) { //Custom handling for arrays
if($is_list) $parts[] = array2json($value); /* :RECURSION: */
else $parts[] = ‘”‘ . $key . ‘”:’ . array2json($value); /* :RECURSION: */
} else {
$str = ”;
if(!$is_list) $str = ‘”‘ . $key . ‘”:’;

//Custom handling for multiple data types
if(is_numeric($value)) $str .= $value; //Numbers
elseif($value === false) $str .= ‘false’; //The booleans
elseif($value === true) $str .= ‘true’;
else $str .= ‘”‘ . addslashes($value) . ‘”‘; //All other things
// :TODO: Is there any more datatype we should be in the lookout for? (Object?)

$parts[] = $str;
$json = implode(‘,’,$parts);

if($is_list) return ‘[' . $json . ']‘;//Return numerical JSON
return ‘{‘ . $json . ‘}’;//Return associative JSON
