PHP - Help With Bash Script To Php

This is a simple permutation function that i was converting from php:

string_gen(){
    declare -a chars=('a' 'b')
    max=4
    let length=${#chars[@]}-1
    n=0
    combination=" "
    for i in `seq 0 $max`;
    do
        let n=($n*($length))+($length)
    done 
    remainder=0
    for i in `seq 0 $n`;
    do
        current=$i
        combination=" "
        while [[ $current > 0 ]]
        do
           remainder=($current%$length)
           echo remainder
           if [ $remainder -eq 0 ]; then
                combination="$combination"${chars[$length]}
            else
                combination="$combination"${chars[$remainder]}
                current = $current/$length
           fi
        done
    done 
    echo $combination
}

What is wrong with the syntax?   Link to PHP version: http://stackoverflow...o-certain-lengt

Hello,

shell_exec("sudo gdfs -o allow_other /var/www/html/gdfs.creds /media/pi/gdrives");

and i changed my sudoers file giving permission www-data. here is my sudoers file content

# This file MUST be edited with the 'visudo' command as root.

Can anyone tell me what i am doing wrong ?

Does anyone already fix the bug. I found something interesting in the error_log file this morning       x.x.x.x - - [25/Sep/2014:01:12:34 -0500]  "GET /cgi-bin/defaul_p.cgi HTTP/1.0" 404 312 "-" "() { :;}; /bin/ping -c 5 "209.126.230.74"        

For those not knowing about this, is a new security hole found in all linux/unix based operating systems that should be patched. http://arstechnica.c...with-nix-in-it/

I have a PHP file in /var/www/html/ called foobar.php with the following content:

Quote

<?php
shell_exec('/usr/bin/env > /tmp/output');
?>

From the backend I can run php foobar.php.  It works as expected.  When I browse to my website and go to foobar.php, the /tmp/output file does not receive anything.  

I set the permissions of the foobar.php file to different settings.  I set the owner and group of foobar.php and /tmp/output to different values.

I tried modifying the httpd.conf file.  When I placed this stanza in the httpd.conf file

Quote

LoadModule php7_module /usr/lib64/httpd/modules/libphp7.so

I could not restart the httpd service.  I tried using just

Quote

LoadModule php7_module modules/libphp7.so

  But this failed too.  

I thought PHP would interpret the file regardless of how I access it (e.g., via a web page and with the php command from a Linux terminal).  How do I get PHP to invoke a Bash command when someone visits a .php web page?

Hi everyone!

I've been working on a php script to replace links that contain a query with direct links to the files they would redirect to.

I'm having trouble echoing $year in my script. Listed below is the script, just below ,$result = mysql_query("SELECT * FROM $dbname WHERE class LIKE '%$search%'") or die(mysql_error());, in the script I try to echo $year. It doesn't show up in the table on the webpage. Everything else works fine. Any help wold be appreciated greatly. Thanks in advance.

Hello,

I stored a fsockopen function in a separate "called.php" file, in order to run it as another thread when it needs.
The called script should return results to the "master.php" script.
I'm able to run the script to get the socket working, and I'm able to get results from the called script. I tried for hours but I can't do the twice both 

My master.php script (with socket working):

Code: [Select]
<?php
$command = "(/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR] &) > /dev/null";
$result = exec($command);
echo ("result = $result\r\n");
?>

and my called.php script
Code: [Select]
#!/mnt/opt/usr/bin/php-cli -q
<?php
$device = $_SERVER['argv'][1];
$port = "8080";
$fp = fsockopen($device, $port, $errno, $errstr, 5);
fwrite($fp, "test");
fclose($fp);
echo ("normal end of the called.php script");
?>

In the master script, if I use
Code: [Select]
$command = "(/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR] &) > /dev/null";
the socket works, but I have nothing in $result
(note also that I don't anderstand why the ( ... &) are needed!?)

and if I use
Code: [Select]
$command = "/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR]";
I have the correct text "normal end of the called.php script" in $result but the socket connection is not performed (no errors in php logs)

Could you help me to find a way to let's work the two features correctly together?
Thank you.

Well the subject line is pretty explicit.  I found this script that uploads a picture onto a folder on the server called images, then inserts the the path of the image on the images folder onto a VACHAR field in a database table. 
Code: [Select]

The script seems to work fine because I managed to upload a picture which was successfully inserted into my images folder and into the database.
Now the problem is, I can't figure out exactly how to write the script that displays the image on an html page. I used the following script which didn't work.


Code: [Select]

//authenticate user
//Start session
session_start();

       
        //Connect to database
require ('config.php');

$sql = mysql_query("SELECT* FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main' ");
$row = mysql_fetch_assoc($sql);
$imagebytes = $row['image'];
header("Content-type: image/jpeg");
print $imagebytes;







Seems to me like I need to alter some variables to match the variables used in the insert script, just can't figure out which.  Can anyone help??

How would I go about making it to where,, I can tell the script to use a certain extension of php in the script like curl.. ?

Thanks

Hi,

I am trying to run two scripts on one page.  When I use just one script on the page they work however when I place both scripts on the same page one of them disrupts the other script.

This script prevents the other following script from working:

Code: [Select]
ini_set('display_errors', 1);
error_reporting(-1);

{
$query = "SELECT * FROM answers ORDER BY `aid` DESC LIMIT 0, 11";
}

$result = mysql_query($query);

while($row = mysql_fetch_assoc($result))

{

$answer = $row['answer'];
$aid = $row['aid'];

echo "
<div class='questionboxquestion'>
<a href= 'http://www.domain.co.uk/test/easy/answer.php?aid=$aid' class='questionlink'>$answer</a>
</div>
<div class='questionboxnotes'>
</br>
</div>
<div class='questionboxlinks'>
<div class='questionboxcategory'>
<div class='questionboxcategorytitle'>

 <a href= 'http://www.domain.co.uk/test/easy/furniture-category.php' class='questionanswerlink'></a>

</div>
</div>
";
}
Code: [Select]
    <?php if($error) echo "<span style=\"color:#ff0000;\">".$error."</span><br /><br />"; ?>
    <label for="username">Username: </label> <input type="text" name="username" value="<?php if($_POST['username']) echo $_POST['username']; ?>" /><br />
    <label for="password">Password: </label> <input type="password" name="password" value="<?php if($_POST['password']) echo $_POST['password']; ?>" /><br />
    <label for="password2">Retype Password: </label> <input type="password" name="password2" value="<?php if($_POST['password2']) echo $_POST['password2']; ?>" /><br />
    <label for="email">Email: </label> <input type="text" name="email" value="<?php if($_POST['email']) echo $_POST['email']; ?>" /><br /><br />
    <input type="submit" name="submit" value="Register" />

I have an application which runs on more than one server and need to launch one PHP script from another PHP script.  Since this is different than a function call I'm not sure how it's done.  I plan to include parameters in the URL I send and use GETs to pick up parameters in the "called" PHP script.

Thanks for sugestions
