Including a file only when string found

[winningratings]

Can anyone help me out with some code in php

I am trying to include a file but only when a string is found

For example I have several text files stored in a directory called text
There are no other files in this directory except the ones I include on my site - usually randomly

What I want to do now is only include them if a string is found which I will set in the php for the page
There could be a way to include only a maximum of 5 files from the text directory

So I will set a variable say - $keyword = 'HelloWorld' at the top of my page
And then include the files in the text directory which have this keyword

Any ideas much appreciated

Welcome to WebmasterWorld, winningratings.

A conditional include can be written, yes. Here is the pseudo code logic that may work for you, you'll have to fill in the details.

<?php 
$count = 5; 
$keyword = 'HelloWorld'; 
while (looping through directory) { 
  $fileName = current file name; 
  $fileContents = read file contents as string; 
  if ($keyword found in $fileContents) { 
    require_once $fileName; 
  } 
  if (!(--$count)) { 
    break; 
  } 
} 
?>
