PHP Search Engine (Files in a directory)

[yanjchan]

Hello!

Yes, I know on the index page it shows how to make a simple mysql search engine. However, I would like to make this search engine without using mysql if possible, so that I don't have to manage a database.

I've been trying to modify a piece of code for hours. 

 

This is, basically, the original file.

<?php
if ($_GET['name'] != '') {
$files = glob('maps/*.*');
$results = array();
$query = explode(' ', $_GET['name']);
foreach ($files as $file) {
	$x = 0;
	if (stripos(basename($file), $query[0]) !== false) {
		$results[] = $file;
	}
}
if (count($results) > 0) {
	echo count($results).' files matched the search <em>' . htmlentities($_GET['name']) . "</em>:<br /><br />\n";
	foreach ($results as $file) {
		echo '<a href="' . $file . '">' . basename(substr_replace($file ,"",-) . '</a><br />' . "\n";
	}

} else {
	echo 'No files matched the search <em>' . htmlentities($_GET['name']) . "</em>.<br />\n";
}
} else {
echo 'Search the files:<br />';
}
?>
<br />
<form action="index.php" method="get">
<input type="text" name="name" />
<input type="submit" />
</form>
<?php
$files = glob('maps/*.*');
echo "Searching through ".count($files)." files, with more added daily.<br>";
?>

Anyways, the problem is that if you enter multiple words, (for example, example file,) and the name of the file is something like example blah file, it wont recognize it. Ive tried exploding the query into the component words... But I'm stuck there. 

So now I'm asking the experts to help. Please help me!

Thanks in advance.

Bump?

well first off the following line

 

stripos(basename($file), $query[0]) !== false

 

only checks if the first word of the query is in the file name

 

something like

 

foreach ($query as $q){
if (stripos(basename($file), $q]) !== false){
$results[] = $file;
break;
}
}

 

instead of that if statement will check every word of the query

 

also I think you may want to use the array_push function instead of the line

$results[] = $file;

 

It's been a bit of time since I've tangoed with PhP heavily, but I am not sure if you can add entries into an array that way

 

hope that helps

$results[] = $file works.

Thank you for your example code, I'll try to apply it.

I was confused on how to structure it.

ok just wasn't sure, been doing java lately,

[yanjchan]

Hmm, I'm still not exactly sure. Using that creates duplicates entries, it would seem.

B-bump.

I've tried more things, but still can't get it to work.
