How to change the style of a few echoed pieces of text? - php

Question

<?php
$blacklist = array("no.html", "one.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo "<a href='$entry'><li id='file'>$entry\n</li></a>";
}
}
closedir($handle);
}
?>
What happens here is that every file in the directory (excluding those in the blacklist) get echoed out like so:
1.html
2.html
3.html
4.html
5.html
6.html
7.html
8.html
However, is there any way to style certain elements? For example, every 3 echo's, make the text bigger and the color red.
E.g.
1.html
2.html
3.html
4.html
5.html
6.html
7.html
8.html

Answer 1

Try this. I think it will help you
$i = 1;
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
if($i%3 == 0){
echo "<a href='$entry'><strong><li id='file'>$entry</li></strong></a>";
}else{
echo "<a href='$entry'><li id='file'>$entry</li></a>";
}
}
$i++;
}

Answer 2

Something like this with the counter initialized will do the job.
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
if ($i%3==0)
{
//the echo with the style
}
else
{
echo "<a href='$entry'><li id='file'>$entry\n</li></a>";
}
}
$i++
}
