Q:

How do I insert a variable into a PHP array?

Hey everyone,

I'm currently working on a PHP project and I'm having a bit of trouble inserting a variable into an array. I've been searching online and trying different methods, but nothing seems to be working for me.

Here's an example of what I'm trying to do:

```php
$name = "John Doe";

$array = array(
"first_name" => "John",
"last_name" => $name,
"age" => 25
);
```

I want to insert the value of the `$name` variable into the `last_name` element of the array, but it's not working as expected. I just get the string "$name" instead of the actual value. Am I missing something here?

I've tried using the curly braces `{}` to enclose the variable, but that didn't work either. Do I need to use a different syntax or function to achieve this? Any help or guidance would be greatly appreciated.

Thanks in advance!

Hey,

I had a similar issue before, and the solution lies in using the concatenation operator (`.`) to merge the variable with the string in the array.

Here's what you need to do:

php
$name = "John Doe";

$array = array(
"first_name" => "John",
"last_name" => " " . $name,
"age" => 25
);


By adding a space before the concatenation operator, the variable value will be appended to the existing string in the `last_name` element. This way, you'll get the desired result of having the actual value instead of just the string "$name".

Give it a shot and let me know if it helps!

Hey there,

I've encountered a similar issue before while working with PHP arrays. The problem you're facing might be due to enclosing the variable in double quotes instead of single quotes.

Try modifying your code like this:

php
$name = "John Doe";

$array = array(
"first_name" => "John",
"last_name" => '$name',
"age" => 25
);


By using single quotes around the `$name` variable, PHP will treat it as a literal string rather than a variable. This should fix the problem and insert the actual value of the variable into the `last_name` element of the array.

Give it a try and let me know if it works for you!
