Script php that search files - php

Question

I'm working on a project using Drupal7 that uploads PDF files into a directory,
and was wondering if there is a PHP script that allows me to search in the uploaded files.
For example, if I write in the search box "JAVA", it will return all the files that have the "JAVA" as part of the content.

Answer 1

function searchFiles($needle, $haystack){
$found = array();
$FILES = scandir($haystack);
foreach($FILES as $FILE){
if("." === substr($FILE, 0, 1)) continue;
try{
$content = file_get_contents($haystack."/".$FILE);
if(strpos($content, $needle) !== false) array_push($found, $FILE);
}catch(Exception $e){}
}
return $found;
}
$files = searchFiles("some text", "/var/www/html/");
Here's a bash script that will do it without PHP. Upload it to your server then chmod +x it so you can run it. you can then call the script from php with exec.
#!/bin/bash
# Recursively searches the all text files in the current working directoy
# for a given pattern. Search is case-insensitive and regex may be used in the patteren.
# Matches are highlighted.
# Usage: $ lazygrep "somepattern"
PATTERN=$1
DIRSS=$(pwd)
clear
printf "\n\nSEARCHING FOR $PATTERN IN $DIRSS\n\n"
grep -inIEr --color=ALWAYS "$PATTERN" $DIRSS
printf "\n\n"
