PHP Looping – Complete Guide with Example

It is true that sometimes when you’re writing code, you come across a point where you have to write the same code again and again. For such conditions, people use the concept of a loop. So this article covers the aspect of PHP looping and how you can execute it throughout your programming. 

It helps you to save a great deal of time and cover the tasks that are repetitive. Explore our guide further to learn about PHP looping and its usage in the coding field. 

What Exactly is a Loop?

As the name suggests itself, the loop means performing repetitive tasks. The idea of a loop is to perform a simple task again and again until it meets a sudden condition. You can set this requirement based on your aspect and generate a script through a section of code. 

PHP Looping Types:

The purpose of loops is to use them repeatedly to execute one code block, assuming a specific condition is met. The basic idea of a loop is to streamline repetitive programming tasks to work on your energy. PHP supports four different looping designs. 

  • While – Repeats block while the condition meets as a set. 
  • Do-while – This code block executes once before testing them. If the requirement is satisfied, the declaration must be made again until it is.
  • For – PHP looping through a block prior to specifying a number in the counter is reached. 
  • For each – Loops through a code for every element in an array.

What to know about While Loops?

The PHP looping helps you to run a cycle as far as a certain condition turns true. It means that a certain program covers the whole procedure again and again until it meets a certain condition.

When can developers use These Loops?

  • You can use the while loop to run the same code multiple times until certain conditions meet. 
  • You can use the while loop to return the database queries. 

What to Know About Doing While Loops?

The type of this loop is a variant of the while loop. It performs a specific function as a task that provides a long iteration with a given condition. This means that you will be able to run a database query multiple times and add up the content.

Difference Between While and Do…While Loop

The key distinction between the (while loop) and the do and while is that the (while loop) checks the condition. At the beginning of each iteration, it guarantees that the loop will never be run to meet the condition. You need to repeat it until it reaches the null point. 

Even if the conditional turns to false, a (do-while loop) will only be run once since the condition is tested once the loop ends instead of at the start. 

What is For Loops?

You can use the for loop in a structural manner. It helps you to generate multiple results. You need to specify how many iterations you want to run in this loop. Therefore, it helps you to run related comments in a centralized manner.

PHP looping is more or less like Java. It can also be found in C and C++. The definitions of the (for loop) parameters are as follows: 

  • Initialization – you can use this approach to set counter variables. It is checked once unconditionally prior to the execution of the loop’s body. 
  • Condition – Each iteration’s State is evaluated at the beginning of w3schools PHP looping. Once it is true, the statements are performed in a nested manner, and the loop remains in place. The loop is ended if the value is false. 
  • Increment — It updates the loop counter with an additional value. It is assessed at the end of each iteration.

What are For Each Loop?

For each loop is used to generate a loop for PHP looping through the array. The array in the given element is located to a different one as the pointer shifts one by one to another stage. These loops help you to generate an element that processes with each pass. However, the for each is. A loop that is supported by areas only.

Here are a few examples of research loops: 

  • The PHP code to use for each loop block is “for each (…).” 
  • You can use the “$array data” to loop arrays. 
  • The “$array value”  is a variable for temporary use to execute the array’s current item values and store them. 
  • “Block of code” refers to the program code that manipulates the values in a given array.

What is a Break Statement?

You can end a loop execution by the split PHP keyword. It helps you to break the statement while it’s located. This is placed in the statement block so that you can have the freedom to locate it anytime. This command is really important if you want to understand how to extend the PHP looping array. Anytime it is true that an existing loop can immediately declare itself executed, you need to be able to break the signs to make a statement of the switch.

What is the Continue Statement?

The PHP (continue) keyword is used to halt the current iteration of a loop. However, the goal is not to terminate the loop entirely. The statement of your given code should contain the PHP looping command, which is followed by a conditional test, and also contains the (continue) declaration and the split statement. The code that hits the statement skips the rest of the loop code and moves on to the next pass.

Why Use Loops?

We understand how time-consuming and tedious it gets for anyone to replicate a code or write it again and again. Therefore such loops are generated for development program languages. It helps you to run a successful program with the least errors possible.


Fortunately, the PHP looping example, a feature included in many languages of programming, lets you automatically repeat code before certain circumstances are reached. Code repetition is referred to as an iteration, and each execution of the code is considered an iteration. By using loops, you may reduce the number of lines of code which you can make while still making many further changes simple.
