Comparing PHP to ASP - Week 4 - Looping

2 Jun 2010 - tips-tutorials

Welcome to the fourth part of our 5 part tutorial where we will compare PHP with Classic ASP.

The objective of these tutorials is to show you how to do some basic programming in PHP and compare it to how you would do it in Classic ASP using VB Script.

This five part tutorial will be split into five sections:

• Part 1 - The Basics
• Part 2 - String Functions
• Part 3 - Number Functions
• Part 4 - Looping
• Part 5 - Sessions and Cookies

Looping is an important part of any development language. For this tutorial we will look at some of the most common ones used as a developer.

For Loops in PHP

The 'For' loop is used when you know in advance how any items you want to loop through.

For Loops in Classic ASP

Both of these examples would output a sequence of numbers between 1 and 5.

For Each Loops in PHP

The 'For Each' loop is used to loop through an array.

For Each Loops in Classic ASP

Each of these examples will write all three items of the array to the browser.

If Else Statements in PHP

If statements are used if you want some code to be executed if a certain condition is true. If the condition if false, the else part of the statement will be executed.

If Else Statements in Classic ASP

Each of these examples would output "Your variable is greater than 10" because the variable is set to 11 in each example.

I hope you have enjoyed part 4 of our 5 part tutorial. Look out for part 5 on sessions and cookies coming soon.
