For example: for ($i = 0; $i < 5; $i++) { echo $i; // 0 1 2 3 4 } In this example, the variable $i is initialized to 0, and the loop executes until $i is less than 5. If the loop condition evaluates to false, then the loop is terminated. Otherwise, the body of...
To create a never-ending (an infinite) loop, you can usewhile,do...while, orfora loop by passingtrueas the condition of the loop. Infinite while loop Below is an example of an infinitewhileloop - <?phpwhile(true){echo"Hello"; }?> Infinite do...while loop Below is an example of ...
Break out of foreach loop: Example 1 Here, we have an array of the names and breaking the loop execution when a specifiedstring found. PHP code to demonstrate example of break in a foreach loop <?php// array defination$names=array("joe","liz","dan","kelly","joy","max");// for...
For example: “$numbers = array(1, 2, 3, 4, 5); $count = count($numbers);” In the above example, the count() function is used to determine the number of elements in the $numbers array, which is 5. 2) sort(): The sort() function is used to sort an array in ...
The assignment $j = count($array) is part of the for loop, separated by a comma from the $i = 0 assignment. It is only called once at the start of the loop. It is not necesssarily superior to the first "right" example above but it does reduce the number of lines of code by ...

There will be times when using a do-while loop makes more sense than a while loop. However, you will find yourself making use of a plain while loop most of the time. You can nest do-while loops but plan your code carefully to avoid performance issues. For example, heavily nested loops...
The main thing to remember is thatforeachdoes not create a scope. Thus,$valuein the above example is areferencewithin the top scope of the script. On each iterationforeachsets the reference to point to the next element of$array. After the loop completes, therefore,$valuestill points to th...
