I have written my own function for searching files, but it only supports ? and *
However it should be easily expandable.
<?php
// e.g. $matches=GetMachingFiles(GetContents("."),"*.txt");
function GetMatchingFiles($files, $search) {
// Split to name and filetype
if(strpos($search,".")) {
$baseexp=substr($search,0,strpos($search,"."));
$typeexp=substr($search,strpos($search,".")+1,strlen($search));
} else {
$baseexp=$search;
$typeexp="";
}
// Escape all regexp Characters
$baseexp=preg_quote($baseexp);
$typeexp=preg_quote($typeexp);
// Allow ? and *
$baseexp=str_replace(array("\*","\?"), array(".*","."),
$baseexp);
$typeexp=str_replace(array("\*","\?"), array(".*","."),
$typeexp);
// Search for Matches
$i=0;
foreach($files as $file) {
$filename=basename($file);
if(strpos($filename,".")) {
$base=substr($filename,0,strpos($filename,"."));
$type=substr($filename,strpos($filename,".")+1,strlen($filename));
} else {
$base=$filename;
$type="";
}
if(preg_match("/^".$baseexp."$/i",$base) &&
preg_match("/^".$typeexp."$/i",$type)) {
$matches[$i]=$file;
$i++;
}
}
return $matches;
}
And if someone's searching for a function which gets all files from a directory including the
subdirectories:
// Returns all Files contained in given dir, including subdirs
function GetContents($dir,$files=array()) {
if(!($res=opendir($dir))) exit("$dir doesn't exist!");
while(($file=readdir($res))==TRUE)
if($file!="." && $file!="..")
if(is_dir("$dir/$file")) $files=GetContents("$dir/$file",$files);
else array_push($files,"$dir/$file");
closedir($res);
return $files;
}
?>
