What is the correct way to pass a variable to an array in PHP?

When passing a variable to an array in PHP, you need to make sure that the variable is assigned as a value within the array. You can do this by using square brackets and assigning the variable to a specific key in the array. This allows you to access the value of the variable later on by referencing the key in the array. 

// Define a variable
$variable = "value";

// Pass the variable to an array
$array = ['key' => $variable];

// Access the value of the variable in the array
echo $array['key']; // Output: value
