In PHP, how do I concatenate arrays for beginners?

In PHP, concatenating arrays refers to the process of merging two or more arrays into a single array. This is quite useful when you want to combine multiple sets of data. You can achieve this using the `array_merge` function or the `+` operator. Below is an example demonstrating how to concatenate arrays in PHP.

<?php // Define two arrays $array1 = array("apple", "banana", "cherry"); $array2 = array("date", "fig", "grape"); // Concatenate arrays using array_merge $mergedArray = array_merge($array1, $array2); print_r($mergedArray); // Concatenate arrays using + operator (merges by keys) $array3 = array("a" => "apple", "b" => "banana"); $array4 = array("b" => "berry", "c" => "cherry"); $combinedArray = $array3 + $array4; print_r($combinedArray); ?>
