How to merge arrays in one variable in PHP

User 3: Hello everyone! When I faced a similar challenge, I discovered an alternative method that worked well for me. Instead of using array_merge() or array_merge_recursive(), I utilized the array_push() function to merge the arrays into a single variable.

Let me demonstrate how you can apply this approach to your project:

php
$usernames = ['john', 'mary', 'alex'];

$emails = ['john@example.com', 'mary@example.com', 'alex@example.com'];

$phoneNumbers = ['1234567890', '9876543210', '5555555555'];



$merged = [];

array_push($merged, ...$usernames, ...$emails, ...$phoneNumbers);

User 2: Hi there! I've encountered a similar situation before, and the array_merge() function did work as expected for me. However, there might be some other factors causing it to behave differently in your case.

One thing you can try is to ensure that the arrays you're merging are all properly defined and have the correct data. Double-check that each array contains the expected values before performing the merge.

Additionally, make sure that you're assigning the result of array_merge() to a new variable. In your example, you're using the variable `$merged`, but it's worth confirming that you are correctly accessing it later in your code.

If array_merge() still doesn't give you the desired outcome, you could consider using the array_merge_recursive() function instead. This function is designed to merge arrays and preserve duplicate values by creating another level in the merged array. Here's an example:

php
$usernames = ['john', 'mary', 'alex'];

$emails = ['john@example.com', 'mary@example.com', 'alex@example.com'];

$phoneNumbers = ['1234567890', '9876543210', '5555555555'];



$merged = array_merge_recursive($usernames, $emails, $phoneNumbers);

User 1: Hey there! I faced a similar issue when I was working on a project recently. The array_merge() function didn't work as expected for me either. After some research, I found an alternative approach that worked perfectly.

Instead of using array_merge(), you can try using the array concatenation operator, which is the plus sign (+). Here's an example of how you can use it:

php
$usernames = ['john', 'mary', 'alex'];

$emails = ['john@example.com', 'mary@example.com', 'alex@example.com'];

$phoneNumbers = ['1234567890', '9876543210', '5555555555'];



$merged = $usernames + $emails + $phoneNumbers;
