Hi

My php program is working in linux environment but in browser not working ..its shows blank..i mean i make a php one program in /var/www/html folder. i run this program in command prompt its working properly eg.php /var/www/html/test.php but in browser its showing blank.


pleas suggest me how can i solve this issue

Since you don't tell us ANYTHING (version/distro of Linux, show us your PHP code, tell us version of PHP, etc.), we have no idea. Short answer: you have a bug in your code.

Longer answer: look at your PHP logs and your Apache error logs. There is SOME error in your code, preventing a browser from displaying things.

did you check the permissions of the file ? is it readable, executable etc

permission is -rw-r--r--


can i set 777?

try
# chmod 750 (path/to/your/php/script)

What are the group and owner permissions of the script ?
If you are planning to use it with apache , you might have to change those too , unless I am horribly wrong.

We also would appreciate additional details , the error can be elsewhere too , so give in as much possible safe details as you can.

Hi

Thanks for your reply.

I set the permission 777 , and owner and group is Apache

Ok , I would set it 755 or 750 if I were you.

Did you restart the apache service , just in case ?

What distribution / version are you running?

The original permissions are correct. Apache uses a module to "run" php code and therefore all files in the document root folder should be world read only (644).

As stated you need to check the Apache log files for errors where depends on what distribution you are running ( could be /var/log/httpd).

You need to post your PHP script. It is possible the script will work from the command line but not from Apache.

...and...
Is there a reason you're not answering any other questions? You were asked about the PHP log files, Apache log files, and to show us the script. Since you're invoking this with "php /var/www/html/test.php" and it's working, it's most probably *NOT* anything with permissions, and setting it to anything but 644 isn't a good idea.

What is the actual LINK you're putting in the web browser to get this to come up??

Does any php script work for you on Apache?

Try a file with just:

and see if you get anything. If it's blank, the php module probably isn't setup properly in httpd.conf.

Hi

extremely very sorry for the delay response.

<?php

/*if (isset($argc)) {
for ($i = 0; $i < $argc; $i++) {
echo "Argument #" . $i . " - " . $argv[$i] . "\n";
}

$email = $argv[1];
$pass= $argv[2];*/

$email='bshdsbdh.bshdbs@gmail.com';
$pass='test@123';
if(isset($email)){

`echo '8VYABqmL1Z' | sudo echo '[smtp.gmail.com]:587 {$email}:{$pass}' > /etc/postfix/sasl_passwd`;
`echo '8VYABqmL1Z' | sudo postmap /etc/postfix/sasl_passwd`;
`echo '8VYABqmL1Z' | sudo chmod 640 /etc/postfix/sasl_passwd*`;
`echo '8VYABqmL1Z' | sudo chown rootostfix /etc/postfix/sasl_passwd*`;
`echo '8VYABqmL1Z' | sudo systemctl reload postfix`;

}
else {
echo "argc and argv disabled\n";
}


this is my php script, in command line its working properly.

PHP works differently from the command line versus web server.

Since the web server typically runs as the apache user and as far as I know it does not have sudo rights.

Hi

Thanks for your quick reply. am new in linux environment so next what should i do, please guide me

Right; so again, you have ignored most of the questions asked:

• Version/distro of Linux?
• Version of PHP?
• Have you checked the PHP and Apache error log files? What do they say?

And your entire script **DOES NOT** put anything on the screen...you've got nothing to actually display something in a web browser, so your code is doing exactly what it should. PHP works the same on any platform, so being new to Linux doesn't matter in this case. Are you also new to PHP??

In order for your script to work through your browser, you'll have to add the Apache user (wwwrun, apache, etc...can't tell you, since you won't tell us what version/distro of Linux you're using), to sudoers or to the wheel group. Which is an **INCREDIBLY BAD IDEA**, since you're going to be allowing a web-facing user root access to your system. Don't do that.

It would be far better to have an external shell-script that takes two command-line arguments, and in that shell script have the sudo command assume an elevated permission status. Set ONE USER up in sudoers to have access to ONLY that shell script, to mitigate any potential damage. Call it like:
Then the $result variable will be whatever the return code/output of that script is. At that point, your PHP code can display it with simple echos
