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.

With stripos, you can find them.
http://www.php.net/manual/en/function.stripos.php

PHP Code:

$my_file = file_get_contents("filename.html");
if(stripos($my_file,$keyword)!==false){
  echo "Keyword found";
}
else{
  echo "keyword not found";
}

You just wanted to increase your comments counter or what?

sorry for my curiosity but is what you are asking for is a search engine thing.

if they input multiple words, split it up into an array using explode() and then you could also use strcmp, however i think that it might need an exact match for that...

The strncmp() function compares two strings.
This function returns:

• 0 - if the two strings are equal
• <0 - if string1 is less than string2
• >0 - if string1 is greater than string2

strncmp(string1,string2,length)
