As well as many general scripts many of the scripts could be used in affiliate marketing.
PHP is a "recursive acronym" which stands for PHP Hypertext Protocol. It is used in conjunction with HTML or XHTML to create dynamic web pages
For instance you can use PHP to tell you that today is 23/02/2017 or in American 02/23/2017 and it is a Thursday in the month of February. It can also print data taken from a database.
Here are a few reasons why PHP is more popular than other scripting languages.
In general Linux/Apache servers with PHP are much cheaper than Windows(ASP), Java, Plesk or Coldusion(CFM) servers however it pays to shop around as the cheapest Windows servers may cost less than a more expensive Linux server.
Ease of use
If you have no previous knowledge of any programing language it is impossible to say which one is easier to use. But there are many more books and tutorials available for teaching yourself PHP also the PHP Manual is easily accessible.
Because of the "Open Source" nature of PHP there are many fully functional website scripts freely available from places like Sourceforge. Many Linux/PHP servers also offer "fantastico", a collection of PHP scripts with many of the more popular Content Management Systems, Blogs and Forums ready for immediate installation.
