What are the potential reasons for a PHP table output on a webpage to appear incorrectly multiple times?

The potential reasons for a PHP table output on a webpage to appear incorrectly multiple times could be due to the table being generated within a loop that is iterating multiple times, causing the table to be duplicated. To solve this issue, ensure that the table generation code is placed outside of any looping structure so that it is only generated once.

// Incorrect way of generating the table multiple times within a loop
foreach ($items as $item) {
    echo "<table>";
    // table content generation
    echo "</table>";
}

// Correct way of generating the table only once outside of the loop
echo "<table>";
foreach ($items as $item) {
    // table content generation
}
echo "</table>";
