What is the issue with directly accessing a returned array in PHP?

Directly accessing a returned array in PHP can lead to potential issues such as modifying the original array unintentionally or not properly handling the array data. To solve this issue, it is recommended to assign the returned array to a variable and then access the array elements through that variable. 

// Incorrect way of accessing a returned array
$myArray = getArray();
echo $myArray[0]; // This can lead to potential issues

// Correct way of accessing a returned array
$myArray = getArray();
echo $myArray[0]; // Accessing array elements through a variable
