Text searching
I want a script that can show the line if the searched word matches. For example
If I search for the words “green red” in text.txt
yellow
green
black
red
blue
then it will show the second and fourth line
Is is possible ??

<?php
function search_words_file($words, $file)
{
# note: assumes $words will be space-separated list
# read file into array of lines:
if(!is_readable($file))
{
return(FALSE);
}
$text = file($file);
# create regexp:
$search = "/";
foreach(explode(" ", $words) as $word)
{
$search .= "$word|";
}
$search = rtrim($search, "|") . "/i";
return(preg_grep($search, $text)); # returns array of matched lines
}
# test it:
$test = search_words_file("red green", "test.txt");
foreach($test as $line)
{
$line = trim($line);
echo "<p>$line</p>n";
}
?>
