I have Trying to use MemCached but its showing "class not Found error"
$Memcached = new Memcached();
$Memcached->addServer('127.0.0.1', 11211);
But when i Use Memcache everything works Fine :-
$memcache = new Memcache;
$memcache->connect("127.0.0.1",11211);
I have placed memcache.dll file in php ext directory and enable it in php.ini and i have also installed memcache.exe in windows as a service.
Just want to know what i am missing or what i need to do differently as memcache works like a charm while Memcached is showing error.
EDIT:-
Memcache is installed and visible in the phpinfo file, thats why memcache is working but memcached is not working.I guess memcached is not feasible with windows.

its been 3 days of research, google and frustration to make imagick work on my XAMPP box. I can get as far on making it as php module. But it cannot detect supported formats.
As you can see, I currently have 3.1.2 installed, but I actually worked all the way from the most recent 3.4.1 and jumping from those releases tagged with stable but I just can't make it work.
When I try to run:
<?php
$handle = fopen('http://xxxxx.png', 'rb');
$img = new Imagick();
$img->readImageFile($handle);
$img->thumbnailImage(100, 0);
echo $image;
I am getting:
Uncaught exception 'ImagickException' with message 'Unable to read image from the filehandle' in xxxxx:5 Stack trace: #0 xxxxx\index.php(5): Imagick->readimagefile(Resource id #3) #1 {main} thrown in xxxxx\index.php on line 5
What I have is:
Windows 8.1 64-bit
PHP 5.6.12, x86, TS
(http://i.imgur.com/2pnneqO.png)
This is what I actually have done so far, in terms of installing it:
Download any -Thread Safe (TS) x86 package from
https://pecl.php.net/package/imagick
Extract the .zip (1) php_imagick.dll to C:\_XAMPP\php\ext (2)
Extract CORE_RL_* files to C:\_xampp\apache\bin
Download ImageMagick-7.0.1-1-Q16-x86-dll.exe from
Link
Installed it at C:\ImageMagick
Add MAGICK_HOME to environment PATH. http://i.imgur.com/jQAWl3W.png
All *_.dll file in C:\ImageMagick\modules\coders copy to
C:\_Xampp\apache\bin
All *_.dll file in C:\ImageMagick\modules\coders copy to
C:\ImageMagick\
Restart Apache via Xampp
And still can't make my PHP detect Imagick supported file formats even though they should be http://prntscr.com/b1l54u :((
Can somebody tell me what did I miss? Please?
You seem to be going a bit of a convoluted route.
The method I used to install it when I had it running was:
Download and install Ghostscript with an exe file
Download and install imagemagick with an exe file - make sure you let it add the path to the environmental variables. You may not need this step but I wanted to use Imagemagick I'm my website and on my computer anyway.
Download the Imagick dll file and put it in the recommended folder - I can not remember which now.
Uncomment the Imagick option in the php.ini file. I had
two or three php.ini files on my system and I did it in each one.
Turned off the computer and restarted. Started XAMPP and it worked.
This only worked for a couple of installs and when I upgraded the operating system I could not get it to work due to incompatible versions of php and the Imagick.dll. If I should ever want to use Imagick I would do it on my server as the hosts installed it there for me.
You can still write your code locally and test it on your production server. It is a bit of a pain but would probably be quicker/easier than trying to get Imagick working on your PC.
Out of interest I gave up with it and use Imagemagick with exec() and the command line.
I installed the Couchbase Server and its PHP SDK through brew install libcouchbase on Mac. The server admin console is running/working fine on http://127.0.0.1:8091/. I added a hello.php file with the below code in /Library/WebServer/Documents/hello.php.
<?php
$cb = #new Couchbase("http://127.0.0.1:8091/",'username','password');
if($cb->getResultCode() != COUCHBASE_SUCCESS){
throw Exception('Cannot connect to couchbase!');
} else {
echo "Hello World!";
}
When I go to http://127.0.0.1:8091/hello.php, I get an error saying Not found.. What is the problem?
When I go to http://127.0.0.1:8091/hello.php, I get the below error
Not found.. What is the problem?
You are going to the wrong port. Port 8091 is the Couchbase Server Console interface. It looks like you are trying to deploy your hello.php script using the Apache server shipped with OS X which uses the default http port (80). The script is also located in the wrong folder. I believe /Library/WebServer/Documents/ is for static content only.
Given the problem you have ran into it make me suspect that you are trying to learn too many new things at once. You should try running the script outside of a Apache first and get it working there.
php hello.php
It is also worth pointing out that you are using the older 1.X version of the Couchbase PHP SDK, you will want to use the new 2.X version.
I assume you've anonymized the code above, but be sure in place of where you have 'username' you have the bucket name and similarly for the bucket password or empty string if no password. Also, check the docs as the connect string you're using is not necessarily the preferred..
Note for debugging these kinds of things you can set LCB_LOGLEVEL to a higher level as mentioned in the documentation. The way you set an envvar varies based on how you're deploying PHP, but you can easily just test it at the command line.
Is there any way to have Cassandra PDO at Windows with Wamp?
This is for development purposes I don't want to install Linux and change all the environment.
https://code.google.com/a/apache-extras.org/p/cassandra-pdo/
I'm using Windows 7 (64 Bit), Wamp 2.5, PHP 5.5.
OK, here's what I found out:
1) It's totally possible
2) The docs that appear in the first google search results are a bit obsolete
Start by downloading the latest Datastax Community Cassandra here:
http://planetcassandra.org/cassandra/
Install & setup properly. In fact, most of the configuration is done by the installer, you just have to edit the apache-cassandra/conf/cassandra.yaml file to find all paths to /var/lib... and change those into something like d:/cassandra/... That includes "commitlog", "data", "saved_caches". Restart the Cassandra service, examine the logs. Mine shown no problem. The OpsCenter at ...:8888/opscenter/index.html was working fine, showing one node online.
Now, the PHP part.
There's a sneaky thing called Thrift. From what I've learned today (I first heard about Cassandra and Thrift yesterday), it's a way describe a binary protocol of connecting to some online service, in this case, to Cassandra. It will basically generate PHP files that will provide all the connectivity you need from PHP itself (no extensions needed).
You will need:
1) The Thrift PHP libs
2) The .exe Thrift compiler
Both can be downloaded here:
https://thrift.apache.org/download
Then use the following command to compile PHP files that will act as a "driver" to connect your PHP applications to Cassandra:
thrift --gen php D:\DataStaxCommunity\apache-cassandra\interface\cassandra.thrift
Put the result in some PHP include_path folder.
Also, find the PHP Thrift libs (in the libs archive from the same download page) and put those in a folder accessible to your script (e.g. include_path or the project folder).
Refer this page:
thrift.apache.org/lib/php
I guess that should help!
I have same problem as you, but when i tried this method, it works correctly for me.
Reference link
Here is a code example, very easy to understand :
<?php
require_once 'Cassandra/Cassandra.php';
$o_cassandra = new Cassandra();
$s_server_host = '127.0.0.1'; // Localhost
$i_server_port = 9042;
$s_server_username = ''; // We don't use username
$s_server_password = ''; // We don't use password
$s_server_keyspace = 'cassandra_tests';
$o_cassandra->connect($s_server_host, $s_server_username, $s_server_password, $s_server_keyspace, $i_server_port);
$s_cql = "CREATE TABLE carles_test_table (s_thekey text, s_column1 text, s_column2 text,PRIMARY KEY (s_thekey));";
$st_results = $o_cassandra->query($s_cql);
I am in windows 7. I installed WAMPServer. Now, I can not load spatialite libraries. It is showing warning..
Warning: SQLite3::loadExtension() [sqlite3.loadextension]: Not
supported in multithreaded Web servers
Here is my total configuration procedure, what I have done...
From this link I got spatialite lib. I copied "libspatialite-1.dll" and paste it to "D:\wamp\bin\php\php5.3.8\ext" which contains php extention dlls.
http://www.gaia-gis.it/spatialite-2.3.1/libspatialite-win-x86-2.3.1.zip
Then I edited php.ini file. I changed the following configuration.
.
sqlite3.extension_dir = C:\libspatialite-win-x86-2.3.1\bin
.
extension=libspatialite-1.dll
.
enable_dl = On
And lastly, I copy and paste all the libraries from my downloaded libspatialite-win-x86-2.3.1 to my project folder(libspatialite.a, libspatialite.dll.a, libspatialite.la) in my php code i write the script as follows...
<?php
$db = new SQLite3('sixcommunes.sqlite');
$db->loadExtension('libspatialite.a');
$rs = $db->query('SELECT spatialite_version()');
while($row = $rs->fetchArray()){
print "<h3>SQLite version: $row[0]</h3>";
}
?>
I do not know what I have done wrong or how to solve this problem?
Haven't seen any answer, so giving my own. I have used spatialite in C#, I think for using Spatialite Extensions you don't have to load libspatialite like a usual PHP extension, instead something similar to this should be done. (this is c# code, just trying to give you an idea)
SQLiteCommand sqliteCommand = new SQLiteCommand(String.Format("SELECT
load_extension('{0}');", "libspatialite-2.dll"), connection);
sqliteCommand.ExecuteNonQuery();
You have to execute Select load_extension("libspatialite-2.dll") on sqlite to use Spatialite.
Hope this helps
I'm busting my brains over this issue (it should be straightforward), but can't seem to find a solution so hopefully one of you can help me. I'm trying to store sessions using php's memcache extension.
I'm running MAMP and have installed the extension correctly (I think...it shows up when I do phpinfo), am running the daemon and can connect to it through php, using something like this:
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");
So I KNOW that php can communicate with the daemon. The problem is when I enable memcache session storage in php.ini and try to do a session_start() it gives me an error that it "Cannot find save handler memcache". This is what is in my php.ini:
session.save_handler = memcache
session.save_path = "tcp://127.0.0.1:11211"
Any help would be much appreciated =(
Some additional info:
Installed using the directions here:
http://lullabot.com/articles/setup-memcached-mamp-sandbox-environment
on OSX 1.6.4 and i put the .so file in the proper directory
Memcached, not Memcache. Same as the name of the class.
session.save_handler = memcached
EDIT since the OP indicated that it was just a typo.
There are some similar stories here:
http://www.dotdeb.org/2008/08/25/storing-your-php-sessions-using-memcached/
http://phpslacker.com/2009/03/02/php-session-clustering-with-memcache/
Did you say "yes" when the installer asked you "Enable memcache session handler support?"
If it doesn't work, try the new Memcached extension (with the D). It's supposed to be better somehow.
If you want to use memcached instead of memcache, make sure you don't have tcp:// in your session.save_path. So you should fix your session.save_path from
session.save_path = "tcp://127.0.0.1:11211"
to
session.save_path = "127.0.0.1:11211"
You might just still need to install the PHP memcached extension, for example yum install php55-pecl-memcached
You will need to enable the memcache session handler support then installing php5-memcache. Which OS are you using and how have you installed it?
