What happens internally when using the same name for an array and a variable?

When using the same name for an array and a variable in PHP, the variable will overwrite the array, causing data loss. To solve this issue, you should always use unique names for arrays and variables to avoid conflicts.

// Incorrect usage of the same name for an array and a variable
$data = array(1, 2, 3);
$data = 4; // This will overwrite the array with a single value

// Correct usage with unique names for array and variable
$dataArray = array(1, 2, 3);
$dataValue = 4;
