thyscorpion Posted March 25, 2006 Share Posted March 25, 2006 hi, i am very new to php and my page requires a search function so that i can show only those lines from my text file matching to the search string. even if a part of the line in teh text in equal to the search string i need to echo it. just to show u what i haved done so far:- [code] $fcontents = file($filename); while (list ($line_num, $line) = each ($fcontents)) { // while there are elements in the array // remove the P tag from each line and print it echo "<b>Movie $line_num:</b> " . str_replace("<p>", "", $line) . "<br>\n"; } fclose($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. (my web host)I just can't find a function in php to search a string for a string. plz help asap.. thanks a ton-Thyscorpion Quote Link to comment Share on other sites More sharing options...
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 Share on other sites More sharing options...
