How can the performance of looping through code lines be improved when displaying PHP code with line numbers in a forum post?

When displaying PHP code with line numbers in a forum post, the performance of looping through code lines can be improved by using the `implode()` function to concatenate the lines into a single string before displaying them. This reduces the number of echo statements needed to output each line individually, which can be slow and inefficient. 

$codeLines = array(
    "Line 1",
    "Line 2",
    "Line 3",
    // Add more lines as needed
);

$codeString = implode("\n", $codeLines);
echo "<pre>" . $codeString . "</pre>";
