Replace text in line $i

[daviga404]

Hi! Basically, I'm making a PHP file that lists things from a file, so if the file contained; '@-Line 1-@@-Line 2-@' it would produce <li><a href="#">Line 1</a></li><li><a href="#">Line 2</a></li>, but I want it so it changes the coding for 1 of every 2 lines. So I've came up with this code:

$myFile = "list.txt";

$fh = fopen($myFile, 'r');

$theData = fread($fh, 100);

fclose($fh);

$oldtxt = array("@-", "-@");

$newtxt = array('<li><a href="#">','</a></li>');

$newData = str_replace($oldtxt, $newtxt, $theData);

$array = explode("</li>", trim($newData));

$lineno = count($array);

$linenofinal = $lineno - 1;

for($i=1;$i<$linenofinal;$i++){

if(($i % 2)=='0'){

 

}

}

The bit that I'm stuck on is inside the if statement. How could I get it to replace for example <li> in line $i with <li class="1in2">

 

Thanks in advance,

$array[$i] = str_replace('<li>','<li class="1and2">',$array[$i]);

$array[$i] = str_replace('<li>','<li class="1and2">',$array[$i]);

Wow. I feel stupid now >.< Thank you so much!
