Yes, it actually does return strings matched. I would not expect your
code, as you typed it, to do what you expect. I realigned things to make
it easier to see what is happening.
With what you have, it is very unlikely that you will ever print out a
match. You are incrementing your counter for every line of the file,
not for every match actually found. Try this code instead:
<?php
$contents=fread($readfile,100000);
$pattern="<a href.*\">";
while(!feof($readfile)) {
$contents=fgets($readfile,4065);
if(eregi($pattern,$contents,$regs)) {
for($i = 0; $i < sizeof($regs); $i++) {
echo "$regs[$i]<br>";
}
}
}
?>
