![]() It loops over the array, and each value for the current array element is assigned to $value, and the array pointer is advanced by one to go the next element in the array. The foreach loop is mainly used for looping through the values of an array. So I have a list of numbers (in PHP, we use the array language construct to contain and identify a list), and each iteration through it we’re seeing a number, which we’re showing to ourselves via an echo command.PHP Overview PHP Tutorial PHP Introduction PHP Installation PHP Basics PHP Basics PHP Syntax PHP Data Types PHP Variables PHP Constants PHP Print and Echo Statements Operators PHP Operators PHP Arithmetic Operators PHP Assignment Operators PHP Comparison Operators PHP Logical Operators PHP Ternary Operator PHP Concatenation Operators Decision Control Structures PHP Decision Making PHP if else statement PHP elseif statement PHP switch statement Loop Control Structures PHP Looping PHP while loop PHP do-while PHP for loop PHP foreach loop Functions PHP Date and Time PHP Functions PHP String Handling Functions PHP Include and Require PHP Headers PHP File Handling PHP Cookies PHP Sessions PHP Sending Emails Compare Strings In PHP array_diff() Function in PHP array_merge() Function in PHP array_search() Function in PHP eval() in PHP preg_replace() Function in PHP URL Encoding and Decoding with PHP sleep() Function in PHP strlen() Function in PHP ksort() Function in PHP strlen() Function in PHP gettype() Function in PHP Forms PHP GET and POST PHP Server Side Form Validation PHP File Upload PHP Classes and Objects PHP OOP Terminology PHP Access Modifiers What is stdClass in PHP? PHP Inheritance PHP OOP Traits PHP Abstract Classes PHP Constructor PHP Destructor Miscellaneous PHP Arrays PHP RSS Feed PHP Composer Environment Variables in PHP PHP Error Handling During each iteration, we can access respective key and value of the associative. Here’s our for loop, made into a simple foreach. To iterate over key-value pairs of array in PHP, we can use foreach statement. The key () function simply returns the key of the array element thats currently being pointed to by the internal pointer. Rather than going through an abstract sequence you iterate over a pre-set thing. ![]() I’ve always found PHP foreach loops much simpler to understand. ![]() If you’ve never seen this syntax before though, it’s a lot to wrap your head around. ![]() Then, it runs the code inside the curly braces. Example 3: In this case, an array of students and their marks are taken in the array. What’s great about this code is that if you’ve seen a for loop before (with its weird three-clause syntax of “start condition”, “continue condition”, “per loop operation”), this reads quite simply. For each element in meal, foreach( ) copies the key of the element into key and the value into value. We will use the same foreach loop to iterate over an array of key-value pairs. You’ll probably use a for loop, like this: for ($x = 1 $x " i get the excel values, but i dont separate the column value, how to i get the columns value. ![]() Let’s say you want a segment of code to run 20 times. Assign an array to Smarty, the key contains the key for each looped value. In PHP, you’ll use a for loop mostly when you want to iterate through a set of numbers. But before we get too deep on the foreach loop I do think there’s value in covering how these two popular things differ. PHP improves on the for loop with the foreach loop. Anyone who’s programmed much in any language has heard of a for loop. ![]()
