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. 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. It starts with the first element and ends with the last one. The foreach statement iterates over all elements in an array, one at a time. 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. PHP provides you with the foreach statement that allows you to iterate over elements of an array, either an indexed array or an associative array.If the condition returns true, then only the loop is executed. It will issue an error if you try to use it with the variables. condition: Here we define the condition which is checked after each iteration/cycle of the loop. The foreach loop is used to traverse the array elements.initialization: Here we initialize a variable with some value. ![]() The parameters used have following meaning: El constructor foreach proporciona un modo sencillo de iterar sobre arrays. 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. 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.
