What are the implications of converting numbers to strings when calculating the byte size of an array in PHP?

Converting numbers to strings before calculating the byte size of an array in PHP can lead to inaccurate results, as the size of a string representation may not accurately reflect the actual byte size of the data. To solve this issue, it is recommended to calculate the byte size of the array directly without converting numbers to strings.

$array = [1, 2, 3, 4, 5];
$byteSize = count($array) * PHP_INT_SIZE;
echo "Byte size of array: " . $byteSize;
