![]() We will learn about arrays in detail in upcoming tutorial. This loop only works with arrays and you do not have to initialise any loop counter or set any condition for exiting from the loop, everything is done implicitly(internally) by the loop. Create a PHP file with the following script to iterate the values of an associative array using a foreach loop and search a particular key in the array. The foreach loop in PHP is used to access key-value pairs of an array. Here is a simple example of nested for loops. ![]() We can also use a for loop inside another for loop. ![]() increment/decrement: Here we increment or decrement the loop counter as per the requirements.Īgain, lets try to print numbers from 1 to 10, this time we will be using the for loop.If the condition returns true, then only the loop is executed. condition: Here we define the condition which is checked after each iteration/cycle of the loop.initialization: Here we initialize a variable with some value.The parameters used have following meaning: The ‘foreach’ loop implicitly does this too. In addition to this, no condition needs to be set that would be needed to exit out of the loop. The ‘foreach’ loop works with arrays only, with the advantage that a loop counter wouldn’t need to be initialized. The for loop in PHP doesn't work like while or do.while loop, in case of for loop, we have to declare beforehand how many times we want the loop to run. It shows how you get the key instead of the index as theres not even a difference because PHP doesnt have the kind of arrays he thinks they have. The ‘foreach’ loop in PHP helps in accessing key value pairs within an array. To understand what are loops and how they work, we recommend you to go through the previous tutorial. ![]() In this tutorial we will learn about for and foreach loops which are also used to implement looping in PHP. ![]()
