PHP exec function

mudasir · Post by **mudasir** » Fri Jan 16, 2009 2:41 am

AOA,

Dear LP members,

I am trying to write a PHP script that will generate directory list using a command

<?php
$cmd="ls -la /sharing/ | awk '{ print $9}'";
$files = array();
exec($cmd, $files);
echo '<pre>';
print_r($files);
echo '</pre>';
?>

This code works almost fine for me except it gives output like this

Array
(
[0] =>
[1] => .
[2] => ..
[3] => Anti-ARP
[4] => Connection-Maker
[5] => SXE
[6] => cbts
[7] => dgb
[8] => diglinux.com.tar.gz
[9] => forum.sql
[10] => forum.tar.gz
[11] => games
[12] => islam
[13] => movies
[14] => rhel
[15] => softwares
[16] => songs
[17] => stage-show
[18] => videos
[19] => voi-vidios
)

Can anyone help me out in removing this ARRAY and the ARRAY numbers and "=>" sign. The output should only be the names of directories.

Looking for a positive and quick reply.

Assalamualaikum,

Please try it as the following

Code: Select all

$cmd="ls -la /sharing/ | awk '{ print $9}'";
$files = array();
exec($cmd, $files);
/*echo '<pre>';
print_r($files);
echo '</pre>';*/

foreach ($files as $file){
	echo '<pre>';
	print_r($file);
	echo '</pre>';
}

It will print the names without those array signs.

Let me know if it doesn't work and you need further help.

AOA,

you're doing it wrong. you're supposed to use the dir functions.

You are right Lambda, I personally prefer to use dir.

And Mudasir you could ignore the . and .. using the following from the list:

Code: Select all

$cmd="ls -la /sharing/ | awk '{ print $9}'";
$files = array();
exec($cmd, $files);
foreach ($files as $file){

	// it checks for empty space or . or .. and ignore them.
	if (($file === "") || ($file === ".") || ($file === "..")){
		//echo "don't print it.";
	}
	else {
		echo '<pre>';
		print_r($file);
		echo '</pre>';
	}
}

just print the <pre></pre> tags around the entire block, not around each item.

AOA,

Thanks allot for the help. I have finally made what i was looking for.

Code: Select all

<?php
$cmd="ls -la /sharing/ | awk '{ print $9}'";
$files = array();
exec($cmd, $files);
foreach ($files as $file){
   if (($file === "") || ($file === ".") || ($file === "..")){
      //echo "don't print it.";
   }
   else {
        echo '<a href=http://172.16.254.2/sharing/' . $file . ' target=_blank>';
      print_r($file);
        echo '</a>';
      echo '<br>';
   }
}
?>

I am not an expert in php, but this is what i made with help from you people.

Thanks again

Now i am making a search script. I will ask again if i get in trouble again

use dir instead of exec.

AOA,

By using DIR function, i have come around with this code.

Code: Select all

<?php
$d = dir("/sharing");
        while (false !== ($entry = $d->read())) {
                if (($entry === "") || ($entry === "." ) || ($entry === "..")){
                //echo "dont print.";
                }
                else {
                echo '<a href=http://172.16.254.2/sharing/' . $entry . ' target=_blank>';
                echo($entry);
                echo '</a>';
                echo '<br>';
                }
}
$d->close();
?>

One more thing, i am making a search script.

This code is of search.php

Code: Select all

<?
if(isset($_POST['submit'])) {
$SEARCH = $_POST['search'];
$CMD = 'find /sharing/ -iname' . $SEARCH;
exec($CMD, $RESULTS);
foreach ($RESULTS as $result){

                echo '<pre>';
                print_r($result);
                echo '</pre>'
}
}
?>

This code is of search.html

Code: Select all

<html>
<head>
<title>Personal INFO</title>
</head>
<body>
<form method="post" action="search.php">
Search:<input type="text" size="12" maxlength="12" name="search"><br />
<input type="submit" value="submit" name="submit"><br />
</form><br />

Please tell me what i am doing wrong in this, its not giving me any reply.

php's documentation page for dir has an example for doing a recursive listing. use that.

AOA,

Dear Lambda bhai,

I dont want to do recursive listing, i want to search for a particular string that will be entered by the user. I searched google but found nothing related to this.

AOA,

I made the search script, but i am facing some issues...The script is below

Code: Select all

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
	"http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<head>
<title>Contact Form</title>
<meta http-equiv="Content-Type" 
   content="text/html; charset=iso-8859-1">
</head>
<body>
<?php
   if ($_SERVER['REQUEST_METHOD'] != 'POST'){
      $me = $_SERVER['PHP_SELF'];
?>
   <form name="form1" method="post"
         action="<?php echo $me;?>">
Search:<input type="text" size="12" maxlength="12" name="Search"><br>
<input type="submit" name="Submit" value="Send"></td>
   </form>
<?php
   } else {
      error_reporting(0);
	$myvar = stripslashes($_POST['Search']);
	$cmd = 'find /sharing/ -iname ' .$myvar. '*';
        $results = array();
	exec($cmd, $results);
	foreach ($results as $result){
	echo '<pre>';
	echo '<a href=http://172.16.254.2' . $result . ' target=_blank>';
	print_r($result);
	echo '</a>';
	echo '</pre>';
}
}
?>
</body>
</html>

The issue is that is shows the complete path, is it possible that is will show only the file name not the complete path.

Second issue that i am facing is that, the space in the path or in the file name is creating problems, it is breaking the path in the link.

Please tell me how can i over come these issues.

Looking for a quick and positive response.

   $myvar = stripslashes($_POST['Search']);
   $cmd = 'find /sharing/ -iname ' .$myvar. '*';
        $results = array();
   $far = exec($cmd, $results);
   $fars = explode("/", $far);
   foreach ($fars as $result){
   if($result === "home")
   {
   }
   else
   {
   echo '<pre>';
   echo '<a href=http://172.16.254.2/' . $result . '/ target=_blank>';
