string comparison

hi

i am writing a small application where a user enters a phrase in the textfield and i would like to display all the files present in the root directory which consists of the keyword or keywords entered by the user.

i have used a few comparison functions but i am not getting the expected result.

$my_file = file_get_contents("filename.html");
what ever the user enters whether it is a single word or few words i would like to compare with $my_file in a case insensitive manner.

can anyone suggest the best method and how to go about.

thanks.

 

stristr is your requested object, or preg_match, try php.net for more info about those functions

 

The concept is like this:

$my_file = file_get_contents("filename.html");
$my_array = explode($my_file, ' ');

// i haven't go through with correct function
// convert all values in array to lowercase, because you need case insensitive
$new_array = array();
foreach ($my_array as $value) {
$new_array[] = strtolower($value);
}

// compare user input case insensitive style
if (in_array(strtolower($your_user_input), $new_array) {
echo "Found";
} else {
echo "Not found";
}

PHP:

Sorry I haven't further tested this as I don't have my eclipse in front of me .
I hope this helps a bit.
