Searching a text file for a string

[thyscorpion]

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

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.preg-match.php\" target=\"_blank\"]http://us2.php.net/manual/en/function.preg-match.php[/a]

Sorry, I meant to post strpos() but it is case sensitive.

Glad to help.

Happy coding.
