PHP SNMP Warning: SNMP::get(): No response from 127.0.0.1 - php

I'm trying to get PHP SNMP to work on XAMPP PHP 7.1.9
I'm always getting this result: Warning: SNMP::get(): No response from 127.0.0.1
Here's what I did:
Enabled php_snmp.dll on php.ini
Installed net-snmp-5.5.0-2.x64
Added windows environment variable MIBDIRS with value C:\usr\share\snmp\mibs
Code I'm running to test:
<?php
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
$sysdescr = $session->get("sysDescr.0");
echo "$sysdescr\n";
$session->close();
I'm new to this so I'm not sure what I'm missing.

The problem was with the MIBDIRS path.
I followed php docs and it says:
The Windows distribution of Net-SNMP contains support files for SNMP in the mibs directory. This directory should added to Windows' environment variables, as MIBDIRS, with the value being the full path to the mibs directory: e.g. c:\usr\mibs.
Problem was I couldn't find c:\usr\mibs on my net-snmp installation so I used C:\usr\share\snmp\mibs instead.
Solution:
I tried using a device with snmp support instead of 127.0.0.1 and ran snmpget on cli and confirmed net-snmp installation actually works. I figured the problem must be with the path php is using to run snmp.
So I used where snmpget to check the command path then changed MIBDIRS environment value with the result which is C:\usr\bin\snmpget.exe

Php, "call to undefined function curl_init()" in browser BUT works fine on cmd

I have a simple test code:
<?php
var_dump(curl_init());
echo '.';
if I run it on command line (Windows 10) I get the expected result:
php.exe test.php
resource(4) of type (curl) .
very fine. But when Im running this file from browser (set to Apache rootdir).
Fatal error: Uncaught Error: Call to undefined function curl_init() in
Im speachless. For legacy reasons, this is php 7.04 (on 7.2, 7.4, 8.1 everything is fine).
The php.ini does work. Of course "extension=php_curl.dll" is enabled. When I change something, for example "max_execution_time = 300", the php_info(); also reinforcements me that these settings are taken into account.
However, the strange thing is what php_info() is saying:
cURL Sterling Hughes
nothing more for curl!
EDIT:
I tried the same with "extension=php_gd2.dll" and it does work if I remove/readd it, phpinfo shows that correctly!
This is because the php folder is not in your system PATH (not user), Apache doesn't know where to search dlls. The easiest way is adding php folder to PATH.
If you doesn't want to do that, you probably need set extension_dir to the full path of your extension folder in php.ini. for example:
extension_dir = "D:\Program Files\php-7.04-ts\ext"
cURL extension needs openssl to work. and you can also find these dlls in php folder, just copy them to Windows or system32 folder. According to RiggsFolly's comment you can copy these required dlls to Apache\bin folder.
libssl-1_1-x64.dll / libeay32.dll
libcrypto-1_1-x64.dll / ssleay32.dll
libssh2.dll

Unable to load Environment Variable Path with Jboss and PHP

I am trying to use the Oracle connectivity by oci_connect function with JBoss (where Server API is CGI/FastCGI), I am unable to show environment variable over phpinfo() function with JBoss(where Server API is CGI/FastCGI), which is already working fine with PHP and Apache.
Below are the parameters which are showing by jboss/(CGI/FastCGI), system environment variable PATH(which is needed to enable the oci8 module of php) and some other parameters are missing with JBoss.
CGI/FastCGI Environment
Variable Value
PHP_FCGI_CHILDREN 5
PHP_FCGI_MAX_REQUESTS 10000
REDIRECT_STATUS 200
SystemRoot C:\WINDOWS
__COMPAT_LAYER ElevateCreateProcess

PATH C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files (x86)\RSA SecurID Token Common........;
Can anyone provide the help/steps to display the environment variable with JBoss and CGI/FastCGI?
FYI: I am using the window 10 environment.
As I verified the my Project.war file, which has been bundled the php-cgi.exe with php 5.6, here we had the wrong version of java.inc file which Compile The PHP/Java Bridge for PHP library.
I changed my java.inc file then the issue have resolved, and now I can see the oci_connect module inside the phpinfo()
So I realized that, I would have need to use correct java bridge file.
OCI8 Module

OCIEnvNlsCreate() failed - please check that ORACLE_HOME and > LD_LIBRARY_PATH

ubuntu 16.10 / nginx / php7.0 / oracle 11 xe
I'm trying to connect to the Oracle databas via PHP. And I get the following errors.
$conn = oci_connect('login', 'pass', 'localhost/xe');
Warning: oci_connect(): OCIEnvNlsCreate() failed. There is something
wrong with your system - please check that ORACLE_HOME and
LD_LIBRARY_PATH are set and point to the right directories in
/var/www/blah.php on line 26
Warning: oci_connect(): Error while trying to retrieve text for error
ORA-01804 in /var/www/blah.php on line 26
Really request variables, they will be empty. This code return empty string.
$test = getenv('LD_LIBRARY_PATH')." ".getenv('ORACLE_HOME');
print ("$test");
But in phpinfo() they are displayed.
I can write environment variables to each file, but this is not an option.
putenv("ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe");
putenv("LD_LIBRARY_PATH=-Wl,-rpath,/u01/app/oracle/product/11.2.0/xe/lib -L/u01/app/oracle/product/11.2.0/xe/lib -lclntsh");
What can I do?
I solved it by removing semicolon from the line ;clean_env=no in the file /etc/php-fpm.d/www.conf in case of php-fpm 5.6 in CentOS 6. Hope it will help in newer PHP versions. Remember to restart php-fpm service after making changes to this file.
We dont have the same infrastructure but I just solved this same issue in :
Apache
CentOS7
PHP 5
Oracle 12cR1
The message says :
please check that ORACLE_HOME and LD_LIBRARY_PATH are set and point to the right directories
In apache, there is a file where you can set the environment variable :
/etc/sysconfig/httpd. There has to be a config file for nginx.
I added the required environment variables.
Assuming that
ORACLE_HOME is /oracle/product/12.1.0/dbhome_1
Oracle client was installed under /oracle/product/12.1.0/client
Add :
ORACLE_HOME=/oracle/product/12.1.0/dbhome_1
LD_LIBRARY_PATH=/oracle/product/12.1.0/dbhome_1/lib:/oracle/product/12.1.0/dbhome_1/network/lib:/oracle/product/12.1.0/client/lib
I also added :
TNS_ADMIN=/oracle/product/12.1.0/dbhome_1/network/admin
ORACLE_SID=<your sid>
After updating /etc/sysconfig/httpd I just restarted Apache's service httpd and that was it:
$ sudo systemctl restart httpd
I hope it helps !
This is related to the incorrect NLS_LANG parameter. It was set to 'NA' in my case. The fix is:
Windows - The NLS_LANG must be unset in the Windows registry (re-named is best). Look for the NLS_LANG subkey in the registry at \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE, and rename it.
Linux/UNIX - Here you simply issue the Linux command "unset NLS_LANG"

$PATH environment variable for apache2 on mac

I am trying to get apache/php to recognize the path to my git. I have been researching and looking in all corners of the web and cannot find how to do this. Basically, no matter what I try, when I run echo phpinfo(); the Apache Environment path does not change from /usr/bin:/bin:/usr/sbin:/sbin. And when I run system('echo $PATH'); in PHP, it reads the same.
System Information:
Mac OSX (Lion)
Apache 2 (running as _www)
PHP 5.3.6
Here is what I have tried editing so far:
/etc/profile
~/.bash_profile
~/.profile
/etc/path
/etc/path.d/{NEW_FILE}
Nothing I have tried so far has changed the $PATH variable. Any ideas?
SOLUTION
So here is the final solution. I edited the
/System/Library/LaunchDaemons/org.apache.httpd.plist
and added
<key>EnvironmentVariables</key>
<dict>
<key>PATH</key>
<string>/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/git/bin</string>
</dict>
You can set the PATH environment variable in /System/Library/LaunchDaemons/org.apache.httpd.plist.
More in the docs.
Did you update the PATH environment variable of user '_www'? Apache will read environment variables from the user runs itself. Or, it looks like you didn't restart apache after updating PATH environment variable.
Check out the older discussion :
How do I add paths to the Apache PATH variable?
Setting environment variables in OS X?
And if you want to modify environment variable in PHP, getenv() and putenv() can be a better choice.
getenv : http://php.net/manual/en/function.getenv.php
putenv : http://www.php.net/manual/en/function.putenv.php
$path = getenv('PATH');
putenv( "PATH=$path:/new_path_that_you_want_to_add" );
Important note for El Capitan (Apologies for the new answer - I don't have enough Rep to comment)
On OSX 10.11, the /System/Library folder is protected, so the files can't be edited.
You need to:
Reboot into Recovery Mode (hold CMD + r after the startup sound)
Once in recovery mode, go to Utilities > Terminal
Run:
csrutil disable
Reboot back into OSX - you should now be able to change the files
Once done, go back to recovery mode and run
csrutil enable
Hope that helps
I created this gist that helped me out from the information above:
https://gist.github.com/srayhunter/5208619
My problem was that PHP was not finding a program that we had installed under /usr/local/bin. Once we did the above it all worked and played nice on mac osx.
for ubuntu server, in /etc/apache2/envvars,
for centos server, in /etc/sysconfig/httpd,
to add:
export PATH=<your php cli path>
and restart apache
A similar problem to what I was having installing Derby. The way I solved it was by opening TextEdit. Select File > Open at this point press Shift + Command + . , this will allow you to view all the documents. Head to the user directory and search for a file called ".profile" . Open it and add the export VARIABLE= Value line for example:
export DERBY_HOME=/opt/local/share/java/derby/
Save the document and restart your terminal to see if the changes went into affect.

PHP Extension (memcache|memcached) not showing in phpinfo() but showing in php -m and php -i?

I am getting both modules listed as installed / configured when I use:
php -m
or if I use:
php -i
but when I use:
$m = new Memcache;
// or
$m = new Memcache();
// or
$m = new Memcached();
//or
$m = new Memcached;
I get the following error:
Fatal error: Class 'Memcached' not found
I am running on a Mac - OS X (10.5.7) with default install of apache & php. Additionally, I have memcached running as a daemon on 127.0.0.1:11211 and libmemcache as required by the php-memcached library. I have restarted apache tons of times and even done a machine restart.
Does anyone know why the modules/extensions show up in the command line but not in my phpinfo()? I am literally stumped, after 3 hours of googling, I am just about ready to give up.
Also, please note, my phpinfo() outputs my ini files as follows AND they are both the exact same file:
Configuration File (php.ini) Path: /etc
Loaded Configuration File: /private/etc/php.ini
UPDATE:
Apache is failing to load the extension.
[Fri May 14 04:22:26 2010] [warn]

Does anyone know why or how this would happen? Both of the files referenced above DEFINITELY ARE there. Should I move this question to server fault?
Your webserver is probably using mod_php, which is a seperate bit of code from the standalone (CLI) interpreter. If they are both using the same ini file, and the memcache extension is configured in the ini file, then it sounds like for some reason, the mod_php is failing to load the extension - check your webserver error_log for startup errors.
It may be that the mod_php was compiled without memcache support (most extensions need to have a stub file linked into the php code, even though the bulk of the code is not linked until run time). Or it may be a permissions problem on the shared object file. Or your webserver may be running chroot, and unable to find the extension (which would also mean that although the ini files appear to have the same path, this is relative to different roots).
HTH
C.
because both versions use different php.ini
place your php.ini into location noted in the phpinfo() outout
I would suspect that the issue revolves around permissions. When you run php from comand line, it runs as the user invoking it. When run as an apache module, it runs as "nobody".
I would assume that the memcached.so file, or the directory it's in does not have proper permissions.
I stumpled upon this post and was having the exact same problem with an extension in my php -i but not in phpinfo(). Mine was a permissions problem because of selinux on a CentOS machine. I had to change ownership and permissions and now it is working as expected.
Set php path in environment variables as given below.
Right-click on "My Computer"
Properties
Advanced Tab > Environment Variables
Under System variables, scroll down to find "Path", select and click on Edit.
Add path to your php install on the end (make sure to precede with semi-colon ";"). Example: ";C:\php7"
Click Ok.
