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);
?>
