Get the last referer in PHP

The next tip allows you to simply get the url of the page that refered the user to your php script. If your script is called from within a frame, then you can extract the url of the page hosting the frame. This is why email service providers don't allow frames and sometimes images within email messages, because it's a security threat.

$Url = $_SERVER['HTTP_REFERER'];

echo 'The refering Url is: ' . $Url;

Changing PHP's default SMTP Mail Settings

By default php or your host company has already set the mail settings in the INI file. But you can change these settings by using the ini_set() function:

ini_set("SMTP","mail.yourdomain.com");
ini_set("SMTP_port","25");
ini_set("sendmail_from","info@yourdomain.com");

Using arrays from HTML forms to PHP Scripts

Below we will take data from an html form as an array and then we'll pass it on to a php script then save it and retrieve it from a MySql database:

 Red
 Blue
 Green
 Yellow

 

There must be square bracket after 'colors', this alerts PHP that you're passing an array. Next we'll extract the array and then add it to the database:

$colors=serialize($_POST['colors']); //takes the data from a post operation...
$query=INSERT INTO colors VALUES('$colors');
 

To retrieve the array data from the database, then, you might do this:

$query=SELECT * FROM shirtColors;
$doQuery=mysql_query($query);
$numrows=mysql_num_rows($doQuery);
if($numrows>0)
{
while($colors=mysql_fetch_array($doQuery))
 {
 $colors=unserialize($colors['colors']);
 
 foreach($colors as $shirt)
  {
   print $shirt.', ';
  }
 }
}
else
{
print 'No colors in database.';
}
