I don't have the option of editing the text files to work right. I want
to be able to read an arbitrary text file line by line and process each
one. So I suppose I could do this (?)
<?php
$fd = fopen ("test","r");
while (!feof ($fd)) {
$buffer = fgets($fd, 4096);
if($buffer == '') {
// no \n, must be EOF
break;
}
echo "buffer is $buffer";
}
fclose ($fd);
?>
