file searching.

[meancity]

i need help about searching files in directory, windows system.

suppose i have a folder:docu and sub folder: letter

in docu

apple1.jpg
apple2.jpg
banana.txt
cat.pdf
dog.doc

in letter

apple.txt
rat.pdf
and blah

i need a script that search this folder and its sub-folder to find conresponding files that i need.

suppose i type searching "apple"
then the result return will be apple1.jpg, apple2.jpg and apple.txt.

so how could i do so... i just need some guide line, or reference from someone.

if anyone would like drop me several lines then

appreciate in advance....

$dir="docu"; //name of your dir
$osdir=opendir($dir); //open dir
while($files=readdir($osdir)){ //create an array
							if($files != "." && $files != ".."){
                                $filename=explode(".", $files);
								$dirfiles[]=$filename[0];
							}
}

if(in_array($your_search, $dirsfile)){
	print "is found";
}else{					
                 print "no fuod";
}

I haven't tested that I just did it but try it 😉

This will work

HalfaBee

<?php

function preg_file_search( $dir,$name )
{
if ($handle = opendir($dir)) {
   while (false !== ($file = readdir($handle))) {
        if( $file == '.' || $file == '..' )
            continue;
        else
            if( is_dir( $file ) )
                preg_file_search( $dir.$file , $name ); // do a recursive search of subs

    if( preg_match( $name , $file )   )
        echo "$dir/$file\n";
}
closedir($handle);
}
}
preg_file_search( "./" , "/php/" ); // search for files with php in them

?>

[meancity]

REALLY thank u both.

ermm i have not tried the code u gave me yet, later i am going to try it.

there is one problem i heard from my friend: sometimes the search will be very slow. so will it be a problem here?

[HalfaBee]

It depends on your system and file structure.

I tested mine on a unix host and it worked fine with a fairly complex dir structure.

Warning: OpenDir: Invalid argument (errno 22) in line (....) c:\program files\apache group\apache\htdocs\fs.php on line

it returns a warning.

the warning point to this line

=>> if ($handle = opendir($dir)) { <<=

any idea of it? or it is because that i am using windows system?🙁

yes i can use this script anyway
with
if ($handle = @opendir($dir))

but i want to know what the problem is.

[HalfaBee]

You may have to change the ./ to \ to make it windows compatable.

Also change the one in the recursive call.

 <?php

   while (false !== ($file = readdir($handle))) { 
        if( $file == '.' || $file == '..' ) 
            continue; 
        elseif( is_dir( $file ) ) 
        preg_file_search( $dir.$file , $name ); // do a recursive search of subs 

    if( preg_match( $name , $file)) 
     {

		echo "$dir"."\\\$file<br>"; 

	}
} 
closedir($handle); 
} 
} 
preg_file_search( ".\\\" , "/php/" ); // search for files with php in them 

?> 

error returns as below

it does list all those files but ... returns errors has usual.

I just tried it on my XP windows server at home and it works ok.

change opendir($dir) to @opendir($dir)

and put at the end of the if
else
echo "Error opening $dir";

To see why it is not working.

ermMMmm..
it seems ... that here is still some problem.
i try to debug it for long time
ok let see this simple script, which list files only, not do the searching.

System: Windows2000
Document root: c:\program files\apache group\apache\htdocs

i made a simple script based on the script you gave me.

<?php

function opend($dir)
{


  if ($dir = opendir($dir)) {

while ($file = readdir($dir) ) {

              if(is_dir($file))
              echo "it is a dir ";

              echo "$file<br>"; 
}//end while  

 closedir($dir);

}//end if

} // end func


opend("./chat");

?>

let's say. in my document root. i have folder named "chat"
and under that "chat" directory there is a folder named"image".

script will open the chat folder and if meets any folder it prints out "it is a dir" and list all files ... conceptually.

but it does not work in this way. even when it meets the "image"(sub-dir of chat), it does not print the "it is a dir ".

then i copy above script to the "chat" folder. change the the last line to be opend("./");, then it prints out "it is a dir image".

it seems the script can't work for 2nd level of sub-directory. only work in direct 1st level sub-directory..... is it a WINDOWS platform problem...

so strange.... it bothers me a lot.

can u help me again... or anyone else has any experince or... idea of it....

really appreciate if anyone can help me on this problem

and i do need to thank HalfaBee a lot.

Hello,

I wish to list *.c files on /tmp dir using php .
Is there any way to do that .

I am using

# check c files on /tmp
function preg_file_search( $dir,$name ) 
{ 
if ($handle = opendir($dir)) { 
   while (false !== ($file = readdir($handle))) { 
        if( $file == '.' || $file == '..' ) 
            continue; 
        else 
            if( is_dir( $file ) ) 
                preg_file_search( $dir.$file , $name ); // do a recursive search of subs 

    if( preg_match( $name , $file )   ) 
        echo "$dir/$file\n"; 
} 
closedir($handle); 
} 
} 
preg_file_search( "/tmp" , "/.c/" ); // search for files with c in them 

but it doesn't work ... it shows all files which contain a "c" and not only files with c extension ..

Any idea ?

Thank you

[HalfaBee]

. means any character in a regular expression.
Try /.c/ instead.

[edit] Why have I work the last 50+ days 12hrs a day without a day off?

HalfaBee

[graziano]

many many thanks , it works .

[graziano]

now the problem is that I need to search *.c files also on subdirectory of /tmp ....

Following script...

# check c files on /tmp
function preg_file_search( $dir,$name ) 
{ 
if ($handle = opendir($dir)) { 
   while (false !== ($file = readdir($handle))) { 
        if( $file == '.' || $file == '..' ) 
            continue; 
        else 
            if( is_dir( $file ) ) 
                preg_file_search( $dir.$file , $name ); // do a recursive search of subs 

    if( preg_match( $name , $file )   ) {
        $cfilecounter = $cfilecounter + 1 ;
        echo "<br>- $dir/$file\n"; 
    }


} 
closedir($handle); 
} 
echo "<b><br>c files on /tmp > -xdxd- $cfilecounter  -ydyd-</b>";
} 
echo "<br>*** c files on /tmp ***"; 
preg_file_search( "/tmp" , "/\.c/"  ); // search for files with c in them 

reports and counts *.c files on /tmp .
But it doesn't report a c files contained on a subdirectory , for example on /tmp/test/test.c ...

What to do to search also on subdirectories ?

Thank you

[HalfaBee]

Try this preg_file_search( "/tmp/" , "/.c/" );

[meancity]

ok i finally find the TRICK

in the recursive call in that function please do like this

preg_file_search( $dir.$file.'/' , $name );

do u see that.... ermmMMmm...

it does bother me for these days.
it keeps on return :
Warning: OpenDir: Invalid argument (errno 22) .

so now it works, yet the script recursively goes into the parent directory and it's direct children directory. it won't go deeper. i mean in windows system. *nix system i've not tried yet.

ok here i got another script which exactly list all your files and directory in ur document root. whatever in, it just lists out all. so it may give friends here a hint for file searching problem.

here comes the code

<?php
function printd($folder){
    $files = array();

$dirs = array();
if ($handle = opendir($folder)) {
    while (false !== ($file = readdir($handle))) { 
        if ($file != "." && $file != ".." && file_exists($folder.$file)) { 
            if(is_dir($folder.$file)){
				//$folder1=$folder.$file;


			   //echo "it is a directory ".$folder1;
			    $dirs[] = $file;
                //printd($dirs[]);

            }else{
                $files[] = $file;
			   //$file;
            }
        } 
    }
    closedir($handle); 
}
echo "<PRE> Directories\n";
print_r($dirs);
   echo "Files\n";
    print_r($files);


$i=count($dirs);
echo $i."<br>";

for ($n=0; $n<$i; $n++ ){
echo "<br>";
$foldern=$folder.$dirs[$n]."/";
	echo $foldern;
printd($foldern);
   }

}

printd('./');

?>

i got this function from others as well, but i did modification of that.
so have a nice try.

really appreciate HalfaBee

and i would like contact u on MSN messenger if u use it
my MSN messenger is:

[e-mail]

or yahoo messenger:
pan_zheng99

thank all.

[HalfaBee]

Sorry don't use msn or yahoo.

when you compare things you have to use the double =. So.. it should be:

=>> if ($handle == opendir($dir)) { <<=

[HalfaBee]

Its not a comparison it should read

if( ($handle=opendir($dir)) !== FALSE )

to be totally correct.
