Anyone know what to do about multiple occurances with strpos? I need to get all of the occurances from a string.
Basically I have a HTML file and I want to grab all the links from it.
strpos, how to do multiple occurances?
do it in a loop...
$occurances = array();
$start = 0;
while($start = strpos($heystack, $find_me, $start)
{
$occurances[] = $start;
}
this will put all occurances in an array called $occurances.. neet or what?

shouldn't you do a
$start++;
after the $occurances.. line?
otherwise it will continue to look at the position where it just found an occurance...
No... I got a java function that does almost the same thing (using String.indexOf().. it works fine there... but you might be right... I havent tried it...

Actually it's "YES" :-)
The code as posted will loop forever if any match is found. You must increase $start by one after ever match of it will start it's next search at the position of the last match, which will be a match immediately, at the same location, which will start searching at the same location which gives a match etc etc...
