Php pages on /var/www/mypage say system("foo.sh"). foo.sh is located on /one/dir and contains command bar.sh that is in /other/dir. For a user using ssh connection and having /one/dir and /other/dir in PATH everything works.
Now, if I put
<Directory /var/www/mypage>
SetEnv PATH . . . :/one/dir:/other/dir
to Apache config, then print getenv("PATH"); on /var/www/mypage/mytest.php shows that /one/dir and /other/dir are in the path. But system() still does not found foo.sh. What's wrong? And after this also foo.sh should see the same PATH so that it will find bar.sh.
I am setting this on Ubuntu 20.04, PHP 7.4.3.
Most likely because just executing > foo.sh would show command not found: foo.sh.
You should specify full/relative path: system('./foo.sh');
I am working on a project where I want to use PHP and Phantomjs together, I have completed my phantomJs script and trying to run it using php exec function. but the function is returning an array of error list.
below I am writing my code of phantomjs and php
dir: /var/www/html/phantom/index.js
var page = require('webpage').create();
var fs = require('fs');
page.open('http://insttaorder.com/', function(status) {
// Get all links to CSS and JS on the page
var links = page.evaluate(function() {
var urls = [];
$("[rel=stylesheet]").each(function(i, css) {
urls.push(css.href);
});
$("script").each(function(i, js) {
if (js.src) {
urls.push(js.src);
}
});
return urls;
});
// Save all links to a file
var url_file = "list.txt";
fs.write(url_file, links.join("\n"), 'w');
// Launch wget program to download all files from the list.txt to current
// folder
require("child_process").execFile("wget", [ "-i", url_file ], null,
function(err, stdout, stderr) {
console.log("execFileSTDOUT:", stdout);
console.log("execFileSTDERR:", stderr);
// After wget finished exit PhantomJS
phantom.exit();
});
});
dir: /var/www/html/phantom/index.php
exec('/usr/bin/phantomjs index.js 2>&1',$output);
echo '<pre>';
print_r($output);
die;
Also tried with
exec('/usr/bin/phantomjs /var/www/html/phantom/index.js 2>&1',$output);
echo '<pre>';
print_r($output);
die;
After runing this i am getting below error
Array
(
[0] => QXcbConnection: Could not connect to display
[1] => PhantomJS has crashed. Please read the bug reporting guide at
[2] => and file a bug report.
[3] => Aborted (core dumped)
)
But if I run index.php file from the terminal like this:
user2#user2-H81M-S:/var/www/html/phantom$ php index.php
then it works fine.I don't know how to solve it. Please help.
i am using following version
system version: Ubuntu 16.04.2 LTS
PHP version: 5.6
phantomJs version: 2.1.1
Did you tried to set an environment variable on your server ? or added it before calling phantomjs ?
I was in the same situation and found some solutions:
a. define or set variable QT_QPA_PLATFORM to offscreen:
QT_QPA_PLATFORM=offscreen /usr/bin/phantomjs index.js
b. or add this line into your .bashrc file (put it at the end):
export QT_QPA_PLATFORM=offscreen
c. or install the package xvfb and call xvfb-run before phantomjs:
xvfb-run /usr/bin/phantomjs index.js
d. or use the parameter platform:
/usr/bin/phantomjs -platform offscreen index.js
Maybe you don't want / can't make modification on your server and in that case you may try to download the static binary from official website then:
/path/to/the/bin/folder/phantomjs index.js
and / or create an alias in your .bash_aliases file like this:
alias phantomjs=/path/to/the/bin/folder/phantomjs
make sure that phantomjs is not installed already on the system if you decide to use the alias.
if the file .bash_aliases not exist already, feel free to create it or add the alias line at the end of the .bashrc file
Some references:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=817277

I had the same problem running phantomjs on headless Ubuntu 18.04 (on the default Vagrant vm install of openstreetmap-website). Folloiwng Jiab77's links, it seems the Phantomjs team says the problem is the Debian package but the Debian team closed the bug as wontfix. I needed phantomjs to "just work" so it can be called by other programs that expect it to work normally. Specifically, openstreetmap-website has an extensive Ruby test suite with over 40 tests that were failing because of this, and I didn't want to modify all those tests.
Following Jiab77's answer, here's how I made it work:
As root, cp /usr/bin/phantomjs /usr/local/bin/phantomjs
Edit /usr/local/bin/phantomjs and add the line export QT_QPA_PLATFORM=offscreen so it runs before execution. Here is what mine says after doing so:
#!/bin/sh
LD_LIBRARY_PATH="/usr/lib/phantomjs:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH
# 2018-11-13: added the next line so phantomjs can run headless as explained on
# https://stackoverflow.com/questions/49154209/how-to-solve-error-qxcbconnection-could-not-connect-to-display-when-using-exec
export QT_QPA_PLATFORM=offscreen
exec "/usr/lib/phantomjs/phantomjs" "$#"
After this change, phantomjs can be run from the command line without changing anything else, and all the tests that depend on phantomjs were successfully passed.
I have a development environment based in docker.
Everytime that I open VSCode I get this message:
Cannot validate since no PHP executable is set. Use the setting
'php.validate.executablePath' to configure the PHP executable.
Somebody know how to set php.validate.executablePath in this case?
I have no idea how to do it.
Here is a screenshot.
Don't forget to escape \
You don't have to add it to the Path
For linux users:
if you don't have PHP installed then first download, then in terminal type
$ whereis php
and it will show path for php executable (It will be either in /usr/bin/php or usr/local/bin/php) which you can copy from terminal.
In VScode goto settings.json file and paste
php.validate.executablePath: /usr/bin/php
In my case using XAMPP is like this
"php.validate.executablePath": "C:/xampp/php/php.exe"
hope that answer your question
Sure, easy. Just follow what it's says.
Go to File> Preferences > Settings ... it will open the settings.json file.
add the following code:
{"php.validate.executablePath": "Here you put your PHP.exe path"}
You have to know where te PHP.exe file is in your computer, search in the php>bin folder.
Hope it works for you
I had the same problem but found the fix here.
In Windows:
Go To System Properties
Go To Advanced Tab
Click "Environment Variables"
Select Path
Add a new path that points to your php 7 executable:
My case, I'm using Laragon, so you should search where is your php.exe.
By VSCode just add.
"php.executablePath": "C:\\laragon\\bin\\php\\php-7.2.19-Win32-VC15-x64\\php.exe"
on settings.json.
VSCode
Linux Users:
Step 1:
In your terminal type
whereis php
In my case "php: /opt/lampp/bin/php"
Step 2:
{
"php.validate.executablePath": "/opt/lampp/bin/php"
}
Download PHP, in my case, I downloaded from here:
http://windows.php.net/download/
Copy and paste the files to a location on your computer, and set the path:
"php.validate.executablePath": "C:/php/php.exe"
"php.validate.executablePath": "C:/php/php.exe" wont work due to incorect escaping
try this;
"php.validate.executablePath": "C:\\php\\php.exe"
If you get this on windows in VS code click on the blue 'open settings' button. Near the bottom of the screen this opens there's a link to enter the settings, click this to open the settings.json file. Edit the file to look like this:
{
"php.executablePath" : "C:/php-7.4.2-nts-Win32-vc15-x64/php.exe",
"php.validate.executablePath" : "C:/php-7.4.2-nts-Win32-vc15-x64/php.exe"
}
where C:/php-7.4.2-nts-Win32-vc15-x64 is the path to your PHP dir
I don't know if this helps but I ran into the same problem with the extension PHP Intelephense in Visual Studio Code. What I did is read the instructions so the extension could work properly. So I disabled PHP Language Features by searching "#builtin PHP" in the extensions. Also, other (3rd party) PHP extensions that provide similar functionality should also be disabled for best results. Finally, I added glob patterns for non-standard PHP file extensions to the files.associations setting. For example: "files.associations": { "*.module": "PHP" }
Doing this made the error go away. I'm new to PHP too, let me know if this is the correct way of solving this problem with PHP Intelephense.
If you're using VScode and have installed Php through MAMP, the default path should be:
C:/MAMP/bin/php/php7.4.1/php.exe
/ not \
Regarding the docker-specific revision of the question, I found this thread in the VS Code PHP Intellisense git repo issue that explains how to create a wrapper script. It will involve mapping volumes, though, so take that into account.
https://github.com/felixfbecker/vscode-php-intellisense/issues/150#issuecomment-330374124
I have ubuntu and XAMPP.
The following worked for me.
Press CTRL + P
Type settings.json and hit ENTER.
Add the following line in settings.json
{
...
"php.validate.executablePath": "/opt/lampp/bin/php",
...
}
Make sure to proper syntax.
I simply used double forward slashes and it worked, like so:
"php.validate.executablePath": "C:\\xampp\\php\\php.exe",
Unix / Linux / Mac / WSL ,
Step 1 : Find PHP path
whereis php
Response will show you where your php directories are.
user#User:~$ whereis php
php: /usr/bin/php /usr/bin/php8.0 /usr/bin/php8.1 /usr/lib/php /etc/php /usr/share/php8.0-opcache
/usr/share/php8.0-xml /usr/share/php8.1-curl /usr/share/php8.1-opcache /usr/share/php8.0-gd
/usr/share/php7.0-gd /usr/share/php7.0-common /usr/share/php8.0-readline /usr/share/php8.0-mysql
/usr/share/php8.0-zip /usr/share/php8.1-mbstring /usr/share/php8.1-xml /usr/share/php8.0-mbstring
/usr/share/php8.0-common /usr/share/php8.0-curl /usr/share/php8.1-readline /usr/share/php8.1-common
/usr/share/man/man1/php.1.gz
Step 2 : Configure VS-Code
Go to -> "Preference -> Settings"
Search for -> "php path"
Then click -> "Edit in settings.json"
In my case I had multiple.So I chose the one I wanted from the available versions and my VS-Code looked like this
"php.validate.executablePath": "/usr/bin/php8.1",
IF using Laragon...Dont forget to change \ to /
"php.executablePath": "C:/laragon/bin/php/php-7.4.5-Win32-vc15-x64/php.exe",
Go to 'Preference' -> 'Settings'
Search for> php path
Then click Edit in settings.json
Then just put your directory with (DOUBLE Backslash).
Here is an example of mine:
C:\\php\\php.exe
Here is the format:
drive:\\folder_name\\php.exe
This should fix the problem.
php.validate.executablePath in laragon
In my case using laragon is like this
"php.validate.executablePath": "C:\\laragon\\bin\\php\\php-7.4.19-Win32-vc15-x64\\php.exe"
php-7.4.19-Win32-vc15-x64 : Note that this part of your file name may be different
I also had this error. I have installed Laragon and this addition in setting.json worked for me.
"php.executablePath":"C:/laragon/bin/php/php-7.2.19-Win32-VC15-x64/php.exe"
"php.validate.executablePath": "C:\xamp\php\php.exe"
this is working for this case
For Wampserver:
Inside settings.json
"php.validate.executablePath": "C:/wamp64/bin/php/php7.4.26/php.exe"
If php is inside a docker container and you don't need it or don't want to install it on you local system, you can create a php wrapper script like it is suggested here: https://github.com/felixfbecker/vscode-php-intellisense/issues/471
I prefer to use the remote container Microsoft extension on vscode and work inside the container itself.
I've used such solution:
First, create a php file inside /usr/local/bin/ and make it executable:
sudo touch /usr/local/bin/php
sudo chmod +x /usr/local/bin/php
Update content of it with:
docker exec $(docker ps --filter name=-app --format '{{.ID}}') php "$#"
So this will find a container with the name -app at the end. I'm using it along with the docker compose where I have php inside some container which has -app at the end of the name. You can check more about filter here.
And then update php.validate.executablePath with /usr/local/bin/php:
{
"php.validate.executablePath": "/usr/local/bin/php"
}
I also got this error message. The path to php.exe was already set in my System Environment Variables.
The error went away when I commented out "php.validate.executablePath": "c:/path/to/php7.2.10/php.exe", in the settings.json file in VSCode.
How can I check whether the server is able to handle SOAP requests at run time ?
I need to verify it before my script is executing.
You can use:
if (extension_loaded('soap')) {
// Do things
}
http://php.net/manual/en/function.extension-loaded.php
From SSH you can run:
php -i | grep Soap
that will return something like:
Soap Client => enabled
Soap Server => enabled
In PHP to check whether SOAP enabled or not use built in function class_exists():
var_dump(class_exists("SOAPClient"));
It also could be user to check any of modules classes.
in the command line type the following:
>> php -r 'echo (extension_loaded("soap")?"LOADED\n":"not loaded\n");'
Hmm... I'm new and I'm bad :
I tried this in a "test.php" file.
<?php
if (extension_loaded('soap'))
{
echo phpinfo();
}
else //will redirect to sth else so you know it doesn't work
{
header("Location: http://localhost/index.html");
die();
}
?>
And I saw myself looking at a "phpinfo()" page with a paragraph called : "soap".
Sorry for the misinterpretation.
To install SOAP :
Check your "php.ini" file, look for "extension".
You should find a line :
extension=php_soap.dll or ;extension=php_soap.dll
";" means it's commented.
Uncomment it.
If you didn't find the line, then put it there.
extension=php_soap.dll
Make sure the dll file actually is in the default folder php/ext.
If it isn't, check on phpinfo() is your version is VC6, VC9 of VC11, go to the php download page : http://windows.php.net/download#php-5.6 and get the correspondant version of php zip file.
Steal their "php_soap.dll" from their /ext folder and put it in yours.
You're all set!
Restart your servers, then go to your phpinfo() test page to check if it works.
Good luck.
Note :
phpinfo() simple test.php file :
<php
echo phpinfo();
?>
in a php file :
<?php
echo phpinfo();
?>
and then look for SOAP and you will see if SOAP is installed and enabled
EDIT : be careful with other solutions using php CLI (Command Line Interface), because you don't have the same php.ini used for the CLI and for your web server (for example apache). Thus it may differ.
Then if you use apache and you want to see if soap is enabled, it's better to indicate the apache php.ini file in the command line, for instance :
php -c /etc/php/apache2/php.ini -i | grep Soap
PEAR packages are not listed in phpinfo(), so if "soap" doesn't appear on your "test.php" page, it's normal !
You can use the phpinfo script to see is SOAP is installed.

I just wanted to take a look at Mongo-DB. But i just don't get it running. I've installed it with PECL and my phpinfo() tells me that the extension is loaded, but when i try to get a connection with
$mongo = new Mongo();
I get this:
Fatal error: Uncaught exception 'MongoConnectionException' with
message ': Transport endpoint is not connected'
Anybody have the same Problem? ... Or any Idea on this?
Please don't take this the wrong way, but have you actually got the server running? Only it looks like your error relates to a failure to connect and you've made no mention of the server or where it is located (localhost on the default port for example)
any server start method, such as "/etc/init.d/mongodb start" or "service start mongodb" will fail, if a stale lock file still exists. In Ubuntu/Debian this is /var/lib/mongodb/mongod.lock. Look for this and delte it, if it exists and seems to be an old one.
check out whether server is running or not..
/etc/init.d/mongodb start
then go to
root#kannan-desktop:~# mongo
MongoDB shell version: 1.6.3
connecting to: test
>
Don't forget to change the IP in your mongod.conf if it's a new installation.
custom string looks like that
mongodb://username:password#host:port/database
First Change the Default db path by following command
$ sudo mkdir -p /data/db/
$ sudo chown id -u /data/db
and then the final command is..
$ mongod --journal
Do not close terminal until you are working with mongoDB
It works for me...
just write mongod in your terminal and will work well
