[Resolved] local command like ftp_nlist?

[jollyollie]

Simple question (I hope!) I would like to search for files in a local directory (on my server) by partial filename. I'd like the results in an array, the way ftp_nlist does.

In one script I wrote, I use the following:

$contents = ftp_nlist($conn_id, "./MA*.zip");

This gives me an array of files to work with, which I can then manipulate in a "for" clause. Can I do a similar local search by partial filename? Hope this isn't too elementary!

i found this function in the comments of the manual. its brilliant. works much the same way as the ls command in linux.

function ls($__dir="./",$__pattern="*.*")
{
 settype($__dir,"string");
 settype($__pattern,"string");

 $__ls=array();
 $__regexp=preg_quote($__pattern,"/");
 $__regexp=preg_replace("/[\\x5C][\x2A]/",".*",$__regexp);
 $__regexp=preg_replace("/[\\x5C][\x3F]/",".", $__regexp);

 if(is_dir($__dir))
  if(($__dir_h=@opendir($__dir))!==FALSE)
  {
   while(($__file=readdir($__dir_h))!==FALSE)
   if(preg_match("/^".$__regexp."$/",$__file))
     array_push($__ls,$__file);

   closedir($__dir_h);
   sort($__ls,SORT_STRING);
  }

 return $__ls;
}

usage;

echo ls('/home','*.zip');

this should output all .zip files in your /home directory.

Thorpe,

Thanks for your reply! I tried it, but no results. I experimented and added an echo statement at the end of the "if" statements and it's not showing up.

It looks to me like there are missing {} brackest with some of the if statements. Are they ok, or is that part of it?

Thanks again.

I can't get it to work, either.

The "missing" brackets seem to be optional ones.

Couldn't a regular pull with a pattern check work? Something as simple as .zip wouldn't even require regex.

<?php
$dir  = '/path/to/folder/'; #Make sure there's the trailing /
$look = '.zip';
$res  = get_list($dir, $look);
if(is_array($res))
   print_r($res);
else
   echo $res;

function get_list($directory, $pattern) {
   $results = array();
   if($open = opendir($directory)) {
      while(false !== ($file = readdir($open))) {
         if(strpos($file, $pattern) !== false)
            $results[] = $directory.$file;
      }
      closedir($open);
      return $results;
   }
   return 'Could not open directory '.$directory;
}
?>

Not tested, completely unsophisticated, but should shoot you a step into the direction you want to go I'd think.

If anyone's interested, here's a version that will work on both Windows (not in safe mode) and Linux:

function ls_sortof($dir = '', $pattern = '') 
{
    if (($dir != '') && (substr($dir, -1) != '/')) {
        $dir .= '/';
    }

if (strpos($_SERVER['SERVER_SOFTWARE'], 'Win') !== false) {
    $dir = str_replace('/', '\\\\', $dir); // Double the backslash
    $par = $dir . $pattern . ' /B';
    $ls = `dir $par`;
} else {
    ob_start();
    passthru('ls ' . $dir . $pattern);
    $ls = ob_get_contents();
    ob_end_clean();
}

$ls_arr = explode("\n", $ls);
foreach ($ls_arr as $key => $value) {
    $ls_arr[$key] = basename(trim($value));
    if (empty($ls_arr[$key])) {
        unset($ls_arr[$key]);
    }
}

if (!$ls_arr) {
    return false;
} else {
    return $ls_arr;
}
}

Usage:

$files = ls_sortof('.', '*.zip');
if ($files) {
    foreach ($files as $each_file) {
        echo $each_file . '<br />';
    }
} else {
    echo 'No files found';
}

Edit: Double backslash line:
$dir = str_replace('/', '\\', $dir);

String hello = "ok";

Installer,

I'm getting the following error:

Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING

It's related to this line:

        passthru('ls ' . $dir . $pattern);

Any ideas?

[Installer]

That's the same error I get if I don't double the backslash on the line where it says "// Double the backslash". So...double the backslash. 🙂

The line should look like this:

$dir = str_replace('/', '\\', $dir); 

[jollyollie]

You're awesome!

I saw that, but thought to myself that it would have been easier to just put in a double backslash than adding a comment to say to do it. Sometimes it really means what it says.

Thanks and sorry for not taking it as literally as I should have!

It's the way it is because of the forum software. There's probably an easy way to get it to show correctly, but I haven't stumbled onto it yet.

BTW, (and I promise to quit posting long code to this thread), here's a slightly improved (imo) version that will let you retrieve the file listing either with or without the path string prepended to the file name:

function ls_sortof($dir = '', $pattern = '', $with_path = true) 
{
    if (($dir != '') && (substr($dir, -1) != '/')) {
        $dir .= '/';
    }

if (strpos($_SERVER['SERVER_SOFTWARE'], 'Win') !== false) {
    $dir = str_replace('/', '\\', $dir);  // Don't forget :-)
    $par = $dir . $pattern . ' /B';
    $ls = `dir $par`;
} else {
    ob_start();
    passthru('ls ' . $dir . $pattern);
    $ls = ob_get_contents();
    ob_end_clean();
}

$ls_arr = explode("\n", $ls);
foreach ($ls_arr as $key => $value) {
    if ($with_path) {
        $ls_arr[$key] = $dir . basename(trim($value));
    } else {
        $ls_arr[$key] = basename(trim($value));
    }
    if (empty($value)) {
        unset($ls_arr[$key]);
    }
}

if (!$ls_arr) {
    return false;
} else {
    return $ls_arr;
}
}
