We will learn about arrays in detail in upcoming tutorial. Table of Contents Types of Loop in PHP Understanding What Is For Loop Importance of Looping Statements Difference Between While Loop and Do While Loop Conclusion Loops are used to repeatedly execute the same block of code as long as a condition is met. Here’s the thing: if, and only if, the key is a numeric literal, then it is automatically converted into an integer at the start of the loop. While loop is used to execute a block of code as long as the set condition is made to be false. 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. Inside foreach loops you can access every key/value pair of the array you are iterating, and sometimes you may need to compare the key with some other value. The foreach loop is used to loop through arrays. The foreach loop in PHP is used to access key-value pairs of an array. Scripting excellence awaits you with this epic guide on loops in. Here is a simple example of nested for loops. We will be covering the for, foreach, while, nested while, and do while loops. We can also use a for loop inside another for loop. The while statement will execute a block of code if and as long as a. 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. foreach - loops through a block of code for each element in an array.If the condition returns true, then only the loop is executed. It tells PHP to execute the nested statement(s) repeatedly, as long as the while expression evaluates to true. condition: Here we define the condition which is checked after each iteration/cycle of the loop. The meaning of a while statement is simple.
