PHP break Statement

Description

Sometimes a situation arises where we want to exit from a loop immediately without waiting to get back to the conditional statement.

The keyword break ends execution of the current for, foreach, while, do while or switch structure. When the keyword break executed inside a loop the control automatically passes to the first statement outside the loop. A break is usually associated with the if.

Example:

In the following example we test the value of $sum, if it is greater than 1500 the break statement terminate the execution of the code. As the echo statement is the first statement outside loop it will print the current value of $sum.

<?php
$array1=array(100, 1100, 200, 400, 900);
$x1=0;
$sum=0
while ($x1<=4)
{
if ($sum>1500)
{
break;
}
$sum = $sum+$array1[$x1];
$x1=$x1+1;
}
echo $sum;
?>

Output:

1800

PHP: Tips of the Day

PHP: How to write to the console in PHP?

Firefox

On Firefox you can use an extension called FirePHP which enables the logging and dumping of information from your PHP applications to the console. This is an addon to the awesome web development extension Firebug.

Chrome

However if you are using Chrome there is a PHP debugging tool called Chrome Logger or webug (webug has problems with the order of logs).

More recently Clockwork is in active development which extends the Developer Tools by adding a new panel to provide useful debugging and profiling information. It provides out of the box support for Laravel 4 and Slim 2 and support can be added via its extensible API.

Using Xdebug

A better way to debug your PHP would be via Xdebug. Most browsers provide helper extensions to help you pass the required cookie/query string to initialize the debugging process.

  • Chrome - Xdebug Helper
  • Firefox - The easiest Xdebug
  • Opera - Xdebug
  • Safari - Xdebug Toggler
