How can you find an array/variable based on its name in PHP?

In PHP, you can find an array or variable based on its name by using variable variables. This means using a variable to dynamically access another variable. You can achieve this by using curly braces around the variable name within double quotes. This allows you to dynamically reference variables based on a string value. 

$variableName = 'myArray';
$$variableName = [1, 2, 3, 4, 5]; // Creating an array dynamically

echo ${$variableName}[2]; // Accessing the third element of the array
