What is PHPCoder?
PHPCoder is a web based front-end to the
Turck MMCache or
encoding functions, both of which are similar to the Zend Encoder product.
Turck MMCache is a free open source PHP accelerator, optimizer, encoder and dynamic content cache for PHP.
It increases performance of PHP scripts by caching them in compiled state, so that the overhead of compiling
is almost completely eliminated. Also it uses some optimizations to speed up execution of PHP scripts.
Turck MMCache typically reduces server load and increases the speed of your PHP code by 1-10 times.
eAccelerator is a further development of MMCache.
PHPCoder enables you to encode your PHP scripts and applications into non reversible byte-code, thus preventing
users of your programs from viewing or altering the source code while having full functionality. Another
excellent use for PHPCoder is to encode your applications PHP configuration files, that way someone viewing your
source code does not see your database login and password information.
In addition to encoding PHP scripts PHPCoder allows you to set restrictions on the encoded scripts, you can lock
a script to a particular server IP address, server host name, visitor IP, or even place a time limit on the script
so it will expire after x amount of time. PHP Coder also allows you to specify Text, HTML or PHP code that
should be prepended and appended to each file before it is encoded, allowing you to easily and securely implement
your own licensing scheme.
To use your encoded scripts your clients simply install the free
(available on Windows and Unix/Linux) or the
Alternatively, you might prefer eAccelerator
or the eAccelerator Loader.
Latest Release: 1.5 -
Older versions are available for download, as well.
Note that the multi-encoder has not so far been updated to V1.5 as I can't really see a need. If there is a
demand, I may well look at it. Please use the SourceForge
Support Requests page for requests.
must be installed (available on Windows and Unix/Linux)
PHP >= 4.1 (4.3.x highly recommended, 4.1 required)
Apache 1.3/2 or other PHP compatable web-server
The latest eAccelerator supports PHP 5 and Apache 2.
These installation steps should be executed on the command line, you can accomplish them through FTP
clients but this document does not cover the steps to do that.
Commands you should type are in
Download the latest version of PHPCoder from
Extract the phpcoder-x.tgz file by issuing the command:
tar zxf phpcoder-x.tgz
(replace phpcoder-x.tgz with the file you downloaded)
Enter the phpcoder directory by issuing the:
cd phpcoder command
Create the files directory and make it writable:
mkdir files; chmod 777 files
Create the encoded directory and make it writable:
mkdir encoded; chmod 777 encoded
PHP Coder should now be installed. To encode programs/scripts simply place them in the files directory and
then go to http://yoururl/phpcoder and run the encoder, your encoded scripts will be in the encoded directory.
For more information see Using PHPCoder.
Once you have installed PHPCoder following the installation steps above it is easy to begin encoding scripts.
First place the script that you want to be encoded in the files
directory (you can do this via FTP but all directories must be chmod 777).
Next telnet into your hosting providor and execute the command
chmod -R 777 /path/to/phpcoder/files
Then visit http://yourdomain/phpcoder, set your options and press the submit button.
Note that you must chmod -R 777 your files directory because PHPCoder will cd into each directory and write
a temporary file while the directory is being encoded, this is so relative paths in your application are not
broken by the encoding process.
The PHPCoder web page has several options you can set before you encode your files, here is a brief run
down on some of them:
When this is set to Yes PHPCoder will encode files in all the subdirectories of the files directory, this is
enabled by default and should be set to Yes unless you have a good reason to set it to No.
Copy Skipped Files:
When this is set to Yes PHPCoder will copy non PHP source files to the encoded directory, this avoids
breaking apps and makes it so it is not necessary to merge encoded/unencoded files manually.
Pre Content Code:
This is Text, HTML, or PHP code (must be enclosed in <?php ?> ) content that will be prepended to each
PHP source file before it is encoded, this is an excellent place to put licensing code, etc.
Post Content Code:
This is Text, HTML, or PHP code (must be enclosed in <?php ?>) content that will be appended to each PHP
source file before it is encoded, this is a good place for copyright notices, etc.
PHPCoder allows you to set several options that restrict the execution of the encoded PHP scripts. These
options range from locking to an IP or to a particular amount of time or all of the above.
Restrict Visitor's IP:
This can be a single IP or a comma-separated list of IP addresses. If it is set only these IP addresses can
view the script, this is a nice feature for a demo that is not feature restricted but is limited to one visitor
IP. In a pinch it could be used for a security measure though this is not recommended.
Restrict Server IP:
This can be a single IP or a comma-separated list of IP addresses. If it is set scripts can only be served from
these IPs. This enables you to lock the script to a particular server(s) by restricting the IP. This is similar
to lock server name but this will prevent the user from moving the script where Restrict Server Name will allow
them to move the script should their server or hosting change, for this reason Restrict Server Name is encouraged.
Restrict Server Name:
This can be a single server name or a comma seperated list of server names; If this is set the script can only be served from one of these server names, example shadonet.com,yahoo.com. This enables you to lock a script to a particular domain name(s) but allow the user to move the script to a new web host or
server as long as it is being served from the same domain.
When a selection is made here the script will expire after the specified amount of time has passed, for example
5 seconds, 1 week, 2 months, etc. This can be used in conjunction with any of the other restrictions.
Alternatively, you can type in the time when the script should expire, for example 01/01/2004 will make the
script expire January 1st, 2004. This field uses the
GNU date and time format.
