Php Tutorial 1.3

 

Session 2

Loops:

1) while - loops through a block of code while a specified condition is true
2) do...while - loops through a block of code once, and then repeats the loop as long as a specified condition is true
3) for - loops through a block of code a specified number of times
4) foreach - loops through a block of code for each element in an array

Conditional Statements:

1) if statement - use this statement to execute some code only if a specified condition is true
2) if...else statement - use this statement to execute some code if a condition is true and another code if the condition is false
3) if...elseif....else statement - use this statement to select one of several blocks of code to be executed
4) switch statement - use this statement to select one of many blocks of code to be executed

Examples

1) Display Array Data in HTML Table Using While Loop:


<?php
echo"<h1>Table Using While Loop</h1>";
