eaccelerator.shm_size
The amount of shared memory (in megabytes) that eAccelerator will use.
"0" means OS default. Default value is "0".

eaccelerator.cache_dir
The directory that is used for disk cache. eAccelerator stores precompiled code, session data, content and user entries here. The same data can be stored in shared memory also (for more quick access). Default value is "/tmp/eaccelerator".

eaccelerator.enable
Enables or disables eAccelerator. Should be "1" for enabling or "0" for disabling. Default value is "1".

eaccelerator.optimizer
Enables or disables internal peephole optimizer which may speed up code execution. Should be "1" for enabling or "0" for disabling. Default value is "1".

eaccelerator.debug
Enables or disables debug logging. Should be "1" for enabling or "0" for disabling. Default value is "0".

eaccelerator.check_mtime
Enables or disables PHP file modification checking . Should be "1" for enabling or "0" for disabling. You should set it to "1" if you want to recompile PHP files after modification. Default value is "1".

eaccelerator.filter
Determine which PHP files must be cached. You may specify the number of patterns (for example "*.php *.phtml") which specifies to cache or not to cache. If pattern starts with the character "!", it means to ignore files which are matched by the following pattern. Default value is "" that means all PHP scripts will be cached.

eaccelerator.shm_max
Disables putting large values into shared memory by " eaccelerator_put() " function. It indicates the largest allowed size in bytes (10240, 10K, 1M).
The "0" disables the limit. Default value is "0".

eaccelerator.shm_ttl
When eaccelerator fails to get shared memory for new script it removes all scripts which were not accessed at last "shm_ttl" seconds from shared memory. Default value is "0" that means - don't remove any files from shared memory.

eaccelerator.shm_prune_period
When eaccelerator fails to get shared memory for new script it tryes to remove old script if the previous try was made more then "shm_prune_period" seconds ago. Default value is "0" that means - don't try to remove any files from shared memory.

eaccelerator.shm_only
Enables or disables caching of compiled scripts on disk. It has no effect, on session data and content caching. Default value is "0" that means - use disk and shared memory for caching.

eaccelerator.compress
Enables or disables cached content compression. Default value is "1" that means enable compression.

eaccelerator.compress_level
Compression level used for content caching. Default value is "9" which is the maximum value

eaccelerator.name_space
    A string that's prepended to all keys. This allows two applications that use the same key names to run on the same host by setting this in .htaccess or in the main configuration file for the whole webserver.

eaccelerator.keys
eaccelerator.sessions
eaccelerator.content
    Determine where keys, session data and content will be cached. The possible
    values are:
    "shm_and_disk" - cache data in shared memory and on disk (default value)
    "shm"          - cache data in shared memory or on disk if shared memory
                     is full or data size greater then "eaccelerator.shm_max"
    "shm_only"     - cache data in shared memory
    "disk_only"    - cache data on disk
    "none"         - don't cache data

eaccelerator.allowed_admin_path
The script paths that are allowed to get admin information and do admin controls

Control panel and disassembler
------------------------------

If you want to use the control-panel you need to compile eAccelerator with --with-eaccelerator-info which is the default value.
You need to copy the control.php file to your webroot and set the path to it in the php.ini or eaccelerator.ini in the eaccelerator.allowed_admin_path directive. If you don't do this you wont be able to see much information and can't control eAccelerator.
You can set the username and password needed to access the control-panel in the control.php file.

When you compile eAccelerator with --with-eaccelerator-disassembler you need to place the dasm.php and PHP_Highlight.php file also in the same directory as the control.php file. The disassembler requires PHP to be compiled with tokenizer support (--enable-tokenizer).
You can set the username and password needed to access the disassembler at the top of dasm.php.
