PHP - Colorized Output Of Bash Script In Php

Hi,
I have a script that reads data from a website and insert this into a DB and every time a record is written into DB the script gives an output on the screen
When I run this script local on my computer it runs ok and the screen update is every 20 or 30 seconds (not realtime) i though this maybe because of my computer is to slow etc.
When I upload this to the server, it's even worse, no updates at all but it does insert the records into the DB.
I believe it must be a setting in the Apache or PHP server.
Anyone please, advice

Thanks

sure, I know how to output a picture with a php script.
the problem is, the host I use, they won't let me edit the php.ini file to look through png files for PHP scripts before outputting.
Of course, it is bad practice anyways...
Is there any way to make it easy for a user to download the image with a .png extension instead of .php. (I know this is done automatically in windows 7, like: image.php.png because it reads the content type).

Any good ideas? =)

I have made a script that reads values from MySQL database and "Echo" them.  When I run the script the variables from the DB are printed on the page as they should be. 

Now I want to make those variables accessible to my C++ application to read.  I am using WinInet functions to communicate with the script. 

Can somebody explain to me what I have to do in my php script be able to access the variables directly.

The below script gets the value $var = $_GET['Version']; that is sent from my C++ app.  It then reads from the DB table the Version number entered in the table.  Then compares the version number from my C++ app to the DB version number.   Now I want to make the Version Number from the DB accessible to my C++ app.  I want to be able to get the exact value stored in: $row['VersionNumber']; with my C++ app.

<?php
$dbhost = 'host';
$dbuser = 'dbusername';
$dbpass = 'dbpass';

mysql_connect($dbhost, $dbuser, $dbpass) or die                      ('Error connecting to mysql');
$dbname = 'MyDbsName';
mysql_select_db($dbname);
$query = mysql_query("SELECT * FROM Users");
$var = $_GET['Version'];
while($row = mysql_fetch_array($query))
{
    if($var == $row['VersionNumber'])
    {
    echo $row['VersionNumber'];
    }
}
?>

I'm writing a script to grab some info from a list of urls in the database, but it just continuously loads and doesn't display anything.

Here's the script:
<?
$username="*****";
$password="*****";
$database="*****";

mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT * FROM dvds";
$result=mysql_query($query);

$num=mysql_numrows($result);

echo "<b><center>Database Output</center></b><br><br>";

$i=0;
while ($i < $num) {

$url=mysql_result($result,$i,"imdb_url");

echo "<b>Getting page: $url</b><br>";

//get the page content
$imdb_content = get_data($url);

//parse for movie details
$name = get_match('/<title>(.*)<\/title>/isU',$imdb_content);
$director = strip_tags(get_match('/<h5[^>]*>Director:<\/h5>(.*)<\/div>/isU',$imdb_content));
$plot = get_match('/<h5[^>]*>Plot:<\/h5>(.*)<\/div>/isU',$imdb_content);
$release_date = get_match('/<h5[^>]*>Release Date:<\/h5>(.*)<\/div>/isU',$imdb_content);
$mpaa = get_match('/<a href="\/mpaa">MPAA<\/a>:<\/h5>(.*)<\/div>/isU',$imdb_content);
$run_time = get_match('/Runtime:<\/h5>(.*)<\/div>/isU',$imdb_content);

//build content
$content.= '<h2>Film</h2><p>'.$name.'</p>';
$content.= '<h2>Director</h2><p>'.$director.'</p>';
$content.= '<h2>Plot</h2><p>'.substr($plot,0,strpos($plot,'<a')).'</p>';
$content.= '<h2>Release Date</h2><p>'.substr($release_date,0,strpos($release_date,'<a')).'</p>';
$content.= '<h2>MPAA</h2><p>'.$mpaa.'</p>';
$content.= '<h2>Run Time</h2><p>'.$run_time.'</p>';
$content.= '<h2>Full Details</h2><p><a href="'.$url.'" rel="nofollow">'.$url.'</a></p>';

//display the content
echo $content;

$i++;
}

//gets the match content
function get_match($regex,$content)
{
    preg_match($regex,$content,$matches);
    return $matches[1];
}

//gets the data from a URL
function get_data($url)
{
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

?>

Hopefully someone better at php can tell me how to fix it! Thanks!

I found this site: http://www.wallpaperama.com/forums/how-to-save-html-output-code-from-php-script-t6898.html

I would like PHP to kick off the following command:
Code: [Select]
arp -a|sed 's/ /,/g'>arp.csv
I also have an executable makeArpFile.sh:
Code: [Select]
#!/bin/bash
arp -a|sed 's/ /,/g'>arp.csv
And I have tried executing it in php with the following:
$arp = exec("bash makeArpFile.sh", $output, $exit_code);
echo("Last line: " . $arp . "\n");
echo("Output: " . $output . "\n");
echo("Exit Code: " . $exit_code . "\n");
/*returns:
Last line: 
Output: 
Exit Code: 127
*/

I also tried just plain old:
$arp = exec("makeArpFile.sh", $output, $exit_code);
echo("Last line: " . $arp . "\n");
echo("Output: " . $output . "\n");
echo("Exit Code: " . $exit_code . "\n");
/*returns:
Last line: 
Output: 
Exit Code: 127
*/


I can run plain old arp>arp.txt but I really need it formatted in BSD style (arp -a>arp.txt) in order to be able to parse it properly later.

Any thoughts?

EDIT:
for fun I made a useBash.sh script that executed "bash makeArpFile.sh" still no luck.

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

im testing the following script and it wont send 1 2 3 until the script has finished executing.

What can i do to flush the buffer after every echo statement??

<?php 

echo "1";
ob_flush();flush();
sleep(5);
echo "2";
ob_flush();flush();
sleep(5);
echo "3";
ob_flush();flush();

?>

Hello,

I am mounting google drive to my raspberry pi with this command from command line;

sudo gdfs -o allow_other /var/www/html/gdfs.creds /media/pi/gdrives

İt is working from command line, but it is not work when i execute it from web browser. Here php content;

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

Can anyone tell me what i am doing wrong ?

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/

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"        

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?

Well I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script:

<?PHP
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
$RepeatIt = -1;
for($g=1; $g!=$RepeatIt+1; $g++)
{
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***

$ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>";
echo $ScanMessage;

***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
}
?>

At the moment it's returning:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.:

So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line.

Any suggestions?

Thanks.
