php array length — How to Get Array Size in PHP (Simple Guide) php array length When working with arrays in PHP, one of the most common questions is: how do I get the PHP array length? In PHP, "array length" usually means the number of elements inside an array. This short guide explains the standard functions and a few helpful tips so you can use php array length correctly in your projects. Primary ways to get PHP array length The most common functions are count() and sizeof() . They behave the same for arrays: 1) count() count() returns the number of items in an array (or properties in an object that implements Countable). <?php $items = ['apple', 'banana', 'cherry']; echo count($items); // outputs: 3 ?> 2) sizeof() sizeof() is an alias of count() . Use either one; most developers prefer count() for clarity. <?php $items = ['a...

in_array PHP – Complete Guide with Examples and Outputs in_array PHP – Complete Guide with Examples and Outputs The in_array PHP function is used to check if a given value exists in an array. It is one of the most commonly used array functions in PHP and works with both indexed and associative arrays. Syntax of in_array PHP in_array(mixed $needle, array $haystack, bool $strict = false): bool $needle – The value to search for. $haystack – The array to search in. $strict – If true , the function also checks the type of the value. Example 1: Basic Indexed Array <?php $fruits = ["Apple", "Banana", "Mango"]; if (in_array("Banana", $fruits)) { echo "Banana is in the list."; } else { echo "Banana is not in the list."; } ?> Output: Banana is in the list. Example 2: Associative Array <?php $person = [ "name" => "John", ...

foreach as php — 5 Real-World Examples You Can Use Today foreach as php — 5 Real-World Examples You Can Use Today The foreach loop in PHP (using the as keyword) is the easiest way to iterate arrays and objects. Below are five clear, Blogger-friendly examples (each code block is escaped so it displays correctly in the post). 1) Indexed Array (simple list) Use this when you have a plain numeric-indexed array. <?php $fruits = ["Apple", "Banana", "Cherry"]; foreach ($fruits as $fruit) { echo $fruit . "<br>"; } ?> 2) Associative Array (key => value) Great for mapping keys to values (like name => age). <?php $person = [ "name" => "John", "age" => 25, "city" => "New York" ]; foreach ($person as $key => $value) { echo $key . ": " . $value . "<br...

php array types php array types Working with arrays in PHP? You'll quickly discover there are different php array types that serve different purposes. Let me break them down in simple terms with practical examples. The 3 Essential php array types 1. Indexed Arrays (Numbered Lists) These are your basic ordered lists where PHP automatically assigns numeric indexes: $colors = ['red', 'green', 'blue']; // Access with: echo $colors[0]; // Outputs "red" Perfect for simple ordered collections where position matters. 2. Associative Arrays (Key-Value Pairs) When you need named keys instead of numbers: $user = [ 'name' => 'Jamie', 'email' => 'jamie@example.com', 'active' => true ];...

  📌 PHP array_pad() Function Tutorial with Examples The array_pad() function in PHP is used to pad an array to a specified length with a specified value . If the array has fewer elements than the target size, it fills the rest with the value you provide. 📌 Syntax: array_pad ( array $array , int $size , mixed $value ): array Parameters: $array → The original array you want to pad. $size → The target size of the new array. Positive value: Pads to the end (right). Negative value: Pads to the beginning (left). $value → The value to use for padding. 📌 How it Works: If the array is already equal to or larger than the desired size, no padding is added. If it's smaller, the function adds the specified value until the array reaches the target size. It returns a new array — the original remains unchanged. 📌 Example 1: Pad Array to the Right <?php $fruits = array ( "Apple" , "Banana" ); $result = array_pad ( $fr...

  📌 What is array_multisort() in PHP? The array_multisort() function in PHP is a powerful tool used to sort multiple arrays at the same time or to sort a multidimensional array by one or more columns . It sorts arrays in parallel while preserving the relationship between the elements in each array. 📌 Syntax of array_multisort() array_multisort ( array & $array1 , array | int $array1_sort_order = SORT_ASC, array | int $array1_sort_flags = SORT_REGULAR, ...) $array1, $array2, ... → Arrays to be sorted. SORT_ASC / SORT_DESC → Optional. Specifies ascending or descending sort order. SORT_REGULAR / SORT_NUMERIC / SORT_STRING → Optional. Specifies the type of sorting. 📌 How array_multisort() Works It sorts the first array. Reorders the other arrays based on the sorted order of the first. Can also be used for multidimensional array sorting by extracting columns using array_column() . 📌 Example 1: Sort Two Arrays Together <?php $names...

PHP array_merge_recursive() — Preserve Numeric Keys 📖 PHP array_merge_recursive() Function — Explained The array_merge_recursive() function in PHP is used to merge two or more arrays recursively. It helps you combine values under the same keys without overwriting any data. Unlike array_merge() , which replaces duplicate keys, this function keeps both values by converting them into arrays. 🔑 Keyword Focus: php array_merge_recursive preserve numeric keys If you're trying to preserve numeric keys while merging arrays in PHP, it's important to know that array_merge_recursive() will reindex numeric keys by default. Let’s see what that means. 📌 Syntax array_merge_recursive(array $array1, array $array2, ...): array Parameters: $array1, $array2, ... – Arrays you want to merge Returns: New merged array. String keys: merged into arrays. Numeric keys: re...
