What are common pitfalls when using arrays in PHP, especially when trying to display them multiple times?

Common pitfalls when using arrays in PHP, especially when trying to display them multiple times, include not resetting the array pointer after iterating through it once and not making a copy of the array before iterating through it multiple times. To solve these issues, you can use the `reset()` function to reset the array pointer and the `foreach` loop to iterate through a copy of the array. 

// Reset array pointer before iterating through it again
reset($array);

// Make a copy of the array before iterating through it multiple times
$copyArray = $array;

// Iterate through the copy of the array
foreach ($copyArray as $value) {
    echo $value . "<br>";
}
