array_combine() Function Use In PHP 8.3 With Example

The `array_combine()` function in PHP 8.3 combines two arrays by using one array for keys and another for its values. Here's a usage example with PHP 8.3. Syntax

<?php
array_combine(array $keys, array $values): array|false
?>

1. $keys: An array of keys. 2. $values: An array of values. Example Here's an example to demonstrate the use of `array_combine()`:

<?php
$keys = ["name", "age", "email"];
$values = ["John Doe", 30, "john.doe@example.com"];
$combinedArray = array_combine($keys, $values);
if ($combinedArray === false) {
echo "The number of elements in the keys and values arrays do not match.";
} else {
print_r($combinedArray);
}
?>

Explanation

1. Arrays to Combine: - `$keys` contains the keys for the new array. - `$values` contains the values for the new array. 2. Combining the Arrays: - `array_combine($keys, $values)` creates a new array where each key from `$keys` is associated with the corresponding value from `$values`. 3. Checking for Errors: - If the number of elements in `$keys` and `$values` are not the same, `array_combine()` returns `false`. 4. Output: - If the arrays are combined successfully, it prints the combined array.

Output

<?php
Array
(
[name] => John Doe
[age] => 30
[email] => john.doe@example.com
)
?>

In this example, `array_combine()` successfully combines the keys and values into a single associative array. If the number of keys and values did not match, it would return `false`.
