Re: Searching for string in text file help?

You can either do "about 10" fgets() in a row, and check each one -- each one will be a single line, unless a line is over 4096 characters... *OR* you could just use fread() and assume the first line is only 4096 (or whatever number you feel is safe) characters total: $contents = fread($fp, 4096); > if(strstr("$contents", "$search_str")) > { > echo "<pre>"; > readfile("$target_filename"); > echo "</pre>"; > } Meta-comment -- If all you have is "$foo" then the quote marks are silly, and you can just use $foo. It will make your code a lot less "cluttered" looking. Works the same, for all practical purposes, but looks nicer. Technically, the "$foo" *might* cause the parser to waste a micro-second longer to figure out that "$foo" is "4" which is 4, instead of just going $foo is 4, but we're not talking measurable performance here, unless it's inside a loop with a zillion iterations... -- Like Music? http://l-i-e.com/artists.htm
