Ok to do this open your terminal and type:

sudo apt-get install postfix

As you are using “sudo” you must set your admin password.

For further configuration settings, type the following into the terminal as a new command :

sudo dpkg-reconfigure postfix

That’s it.

The first way is doing the following:

Using the wp_print_styles tag:

add_action('wp_print_styles', 'add_my_stylesheet');
function add_my_stylesheet() {
 $myStyleUrl = WP_PLUGIN_URL . '/myPlugin/';
 $myStyleFile = WP_PLUGIN_DIR . 'style.css';
 if ( file_exists($myStyleFile) ) {
 wp_register_style('myStyleSheets', $myStyleUrl);
 wp_enqueue_style( 'myStyleSheets');
 }
 }

The second way is printing it on the header file.

add_action('wp_head', 'business_directory_css');
function business_directory_css(){
 global $bizdir_relative;
 echo '<link type="text/css" rel="stylesheet" href="'.get_option("siteurl") . '/wp-content/plugins/myplugin/mycssstyle.css'" />' . "\n";
}

I thing the second one is easier.

Here the function:

<?php
function url_exists($url) {
 $url = curl_init();
 curl_setopt($url, CURLOPT_URL, $strURL);
 curl_setopt($url, CURLOPT_BINARYTRANSFER, 1);
 curl_setopt($url, CURLOPT_HEADERFUNCTION, 'curlHeaderCallback');
 curl_setopt($url, CURLOPT_FAILONERROR, 1); 

 curl_exec ($url); 

 $intReturnCode = curl_getinfo($url, CURLINFO_HTTP_CODE);
 curl_close ($url); 

 if ($intReturnCode != 200 && $intReturnCode != 302 && $intReturnCode != 304) {
 return false;
 }else{
 return true ;
 }
} 

//example :
if(url_exists("http://php.net/manual/en/book.curl.php")) {
 echo"The URL exists";
}else{
 echo"The URL doesnot exist";
}
?>

There are some times that it is necessary to upload a xls as a data base in sql, so to do this there are a powerful tool that allow us to migrate a xls file to a sql database.

The steeps are:

1. Download the script done in php. (download code here: http://scripts.ringsworld.com/database-tools/xls2mysql/)
2. Locate the script some somewehere into the server folder
3. Execute the xls2mysql_step1.php file (doing this must show some image like the following displayed)
4. Select the xls file in the “File Upload” tab (The file must have into the first row the names of the fields )
5. After upload the file the script will show two new tabs, the first one width the caption “Data” that will display a table width the information, and the second one width the caption “Mysql” wiil show the query to create a new table (this table will be the same as the file was called).
6. The last step is to copy and paste to execute the query and generate the table.
