You cant really skip it while reading as the OS moves the file pointer indiscriminatly... However when you pull a line or something you can break values up into things taking out the | character
$fp = fopen("file.txt","r");
while(!feof($fp)) {
$line = fgets($fp,5000);
$array = explode("|",$line);
Now you have your array of different things you can do whatever you want with them. 🙂
Hope this Helps!
