How can variable parsing issues be avoided when accessing array elements in $_POST in PHP?

Variable parsing issues when accessing array elements in $_POST can be avoided by using the isset() function to check if the array element exists before trying to access it. This helps prevent errors or warnings when trying to access non-existent array elements. 

if(isset($_POST['array_element'])) {
    $array_element = $_POST['array_element'];
    // continue processing the array element
} else {
    // handle the case when the array element is not set
}
