"<br>\n"; } fclose($myFile); [/code] currently as u can see i am echoing all the lines. now i need i have added a search option so that only the searched string matches are displayed.. help plz. i use PHP4.

toplay Posted March 25, 2006 Share Posted March 25, 2006 For what you need, any of these type of functions will work:[a href=\"http://us2.php.net/manual/en/function.strstr.php\" target=\"_blank\"]http://us2.php.net/manual/en/function.strstr.php[/a][a href=\"http://us2.php.net/manual/en/function.stripos.php\" target=\"_blank\"]http://us2.php.net/manual/en/function.stripos.php[/a]Otherwise, for more sophisticated searching, the use of regex or PREG will be more powerful (but sometimes more complicated to implement).[a href=\"http://us2.php.net/manual/en/function.ereg.php\" target=\"_blank\"]http://us2.php.net/manual/en/function.ereg.php[/a][a href=\"http://us2.php.net/manual/en/function.preg-match.php\" target=\"_blank\"]http://us2.php.net/manual/en/function.preg-match.php[/a] Quote Link to comment https://forums.phpfreaks.com/topic/5811-searching-a-text-file-for-a-string/#findComment-20703 Share on other sites More sharing options...
