searching a text file

[fix3r]

I want to be able to search for text in a text file.

 

For example if there was this in a text file:

 

php1:mysql1

php2:mysql2

php3:mysql3

php4:mysql4

apple:orange

php5:mysql5

php6:mysql6

php7:mysql7

php8:mysql8

php9:mysql9

 

I want to be able to search for the word "apple" and then echo what is next to it, which would be "orange".

 

How would I go about doing this? Also, if I were to search through these files in php daily with a lot of people searching through them, would my text files become corrupt? Thank you!

<?php

$file = "file.txt";
$search = "apple";

$lines = file($file);
$found = false;

foreach($lines as $line) {
$pieces = explode(":", $line);
if($pieces[0] == $search && !$found) {
  echo $pieces[1];
  $found = true;
}
}

?>
