Just use the offset value within strpos() http://us3.php.net/manual/en/function.strpos.php Modified steps below: 1) Read the file into a variable, like with file_get_contents() 2) Find the numeric position of the first string, maybe with strpos() 3) Find the numeric position of the last string, again, with strpos() 4) use substr() to grab the string in between substr (filestring, firstpos, length ) where length=lastpos-firstpos http://us2.php.net/manual/en/function.substr.php 5) Write string returned in #4 to a file 6) Then use strpos() with the offset, to only search the remaining part of the file 7) repeat steps 2-6 until strpos() returns false. So for a short example, to better explain what I mean: $beg indicates the beginning string and $end indicates the ending string 1) Use file_get_contents() to read file into $string 2) Do strpos($string,$beg) to get the first occurrence of $beg, = $begpos. 3) Do strpos($string,$end) to get the first occurrence of $end, = $endpos. 4) Do substr($string,$begpos,$begpos-$endpos) to get the desired string 5) Write that to file 6) Now do strpos($string,$beg,$endpos) to get the next occurrence of $beg, = $begpos (a new value) 7) Do strpos($string,$end,$endpos) to get the next occurrence of $end, = $endpos (another new value). 8) Do substr($string,$begpos,$begpos-$endpos) using the new $begpos and the new $endpos to get the desired string 9) Write that to file Continue until strpos() returns a false value. If that method doesn't work, then you could try using strstr* (or stristr**) to cut the string size down to only include the portion of the file that you have not yet searched. * http://us3.php.net/manual/en/function.strstr.php ** http://us3.php.net/manual/en/function.stristr.php HTH, -- Doug Registered Linux User #285548 (http://counter.li.org) ---------------------------------------- Random Thought: War is an equal opportunity destroyer.
