Search function for php

Hello,

 

i am looking for a way of searching for all files in a directory containing a certain word in there filename, and then to zip these files and download. Problem is, i have no idea of where to start!! The word in the filename needs to be the username of whichever client i am editting at the time, this is stored in

 

&slide[fname]

 

and i need it to search this directory

 

/wuploads/

 

this is what ive got so far:-

 

array scandir ( string $directory [, int $sorting_order = SCANDIR_SORT_ASCENDING [, resource $context ]] )

 

if im right i think this will scan a directory and list all files, im not sure on how to set this however to only get files that have &slide[fname] in the filename somewhere.

 

 

i then think that the code below will make it all into a zip file, im just not sure on how/if i can glue the two together!

$this -> old_offset = $new_offset; 

$cdrec .= $name;
$this -> ctrl_dir[] = $cdrec;
} 

function file() {
$data = implode("", $this -> datasec);
$ctrldir = implode("", $this -> ctrl_dir); 

return
$data .
$ctrldir .
$this -> eof_ctrl_dir .
pack("v", sizeof($this -> ctrl_dir)) .
pack("v", sizeof($this -> ctrl_dir)) .
pack("V", strlen($ctrldir)) .
pack("V", strlen($data)) .
"\x00\x00";
}
}

// Test this class
$zipTest = new zipfile();
$zipTest->add_dir("images/");
$zipTest->add_file("images/box1.jpg", "images/box1.jpg");
$zipTest->add_file("images/box2.jpg", "images/box2.jpg");

// Return Zip File to Browser
Header("Content-type: application/octet-stream");
Header ("Content-disposition: attachment; filename=zipTest.zip");
echo $zipTest->file();

// Alternatively, you can write the file to the file system and provide a link:
/*
$filename = "output.zip";
$fd = fopen ($filename, "wb");
$out = fwrite ($fd, $zipTest -> file());
fclose ($fd);

echo "Click here to download the new zip file.";
*/

 

any help would be much appreciated!

 

thanks,

gavin
