PHP Cache Correlation

During PHP operation, the PHP engine will process the PHP source code (lexical analysis, parsing, etc.) and then generate opcode.

And then run it again. At this stage can be opcode cache up, when the next need to run the program, it avoids the lexical analysis, grammar analysis, directly take opcode to use.

Eaccelerator is such a program.

View php's opcode with VLD:

Http://pecl.php.net/package/vld/0.12.0/windows

In the above address download VLD, after decompression will Php_vld.dll, copied to the Ext directory.

Revise php.ini, add "Extension=php_vld.dll";

To view opcode, create a new PHP script that executes under CMD

"E:\xampp\php>php-dvld.active=1 e:\htdocs\mytest\n.php" command.

Show Results:

Install Eaccelerator:

Download: http://www.sitebuddy.com/php/accelerators/eaccelerator-windows-binaries

Download down the file after decompression, will dll file, PayPal to Ext

Modify PHP.ini, open

    [Eaccelerator]    zend_extension_ts= "C:/php/ext/eaccelerator.dll"       //path according to the actual situation    eaccelerator.shm_size= "+"       //According to the system memory to set , default 16M, can be changed to 64M    eaccelerator.cache_dir= "c:/php/temp"     //Front created buffer folder    eaccelerator.enable= "1"    Eaccelerator.optimizer= "1"    eaccelerator.check_mtime= "1"    eaccelerator.debug= "0"    Eaccelerator.filter= ""    eaccelerator.shm_max= "0"    eaccelerator.shm_ttl= "0"    Eaccelerator.shm_prune _period= "0"    eaccelerator.shm_only= "0"    eaccelerator.compress= "1"    eaccelerator.compress_level= "9"

To configure Redis:

Download http://www.redis.cn/download.html

After decompression there are two DLL files, all copied to the Ext directory. [I copied to ext, also prompted to find. The final copy to the Php.exe directory is no longer an error].

Modify PHP.ini

Add to

"Extension=php_igbinary.dll

Extension=php_vld.dll "

Restart Apache,phpinfo () to see if it starts.

Test Redis:

$redis = new Redis ();  $redis->connect ("192.168.0.110", "6379");  The PHP client sets the IP and port  //Store a value  $redis->set ("Say", "Hello World");  echo $redis->get ("say");     Should output Hello World    //Store multiple values  $array = Array (' first_key ' = ' first_val ',            ' second_key ' = ' second_val ', '            third_key ' = ' third_val ');  $array _get = Array (' First_key ', ' second_key ', ' Third_key ');  $redis->mset ($array);  Var_dump ($redis->mget ($array _get));
