在php运行期间,php引擎要对php源码进行处理,(词法分析,语法分析等)然后生成opcode。
然后再运行。在这个阶段可以把opcode缓存起来,当下次需要运行这段程序的时候,就避免了再次 进行词法分析,语法分析,直接拿opcode来用。
eAccelerator就是这样的程序。
用vld查看php的opcode:
http://pecl.php.net/package/vld/0.12.0/windows
在上面的地址下载vld,解压后 将 php_vld.dll,拷贝到ext目录下。
修改php.ini,增加“extension=php_vld.dll”;
要查看opcode,新建一个php脚本,cmd下执行
“E:\xampp\php>php -dvld.active=1 e:\htdocs\mytest\n.php”命令。
显示结果:
E:\xampp\php>php -dvld.active=1 e:\htdocs\mytest\n.php Finding entry points Branch analysis from position: 0 Jump found. Position 1 = 13, Position 2 = 6 Branch analysis from position: 13 Return found Branch analysis from position: 6 Jump found. Position 1 = 3 Branch analysis from position: 3 Jump found. Position 1 = 1 Branch analysis from position: 1 filename: E:\htdocs\mytest\n.php function name: (null) number of ops: 14 compiled vars: !0 = $i line # * op fetch ext return operands --------------------------------------------------------------------------------- 30 0 > ASSIGN !0, 0 1 > IS_SMALLER ~1 !0, 100 2 > JMPZNZ 6 ~1, ->13 3 > POST_INC ~2 !0 4 FREE ~2 5 > JMP ->1 31 6 > CONCAT ~3 ‘a‘, !0 7 FETCH_W local $4 ~3 8 ASSIGN $4, !0 32 9 CONCAT ~6 ‘a‘, !0 10 FETCH_R local $7 ~6 11 ECHO $7 33 12 > JMP ->3 36 13 > > RETURN 1 branch: # 0; line: 30- 30; sop: 0; eop: 0; out1: 1 branch: # 1; line: 30- 30; sop: 1; eop: 2; out1: 13; out2: 6 branch: # 3; line: 30- 30; sop: 3; eop: 5; out1: 1 branch: # 6; line: 31- 33; sop: 6; eop: 12; out1: 3 branch: # 13; line: 36- 36; sop: 13; eop: 13 path #1: 0, 1, 13, path #2: 0, 1, 6, 3, 1, 13, 012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364 6566676869707172737475767778798081828384858687888990919293949596979899
安装eAccelerator:
下载:http://www.sitebuddy.com/php/accelerators/eaccelerator-windows-binaries
下载下来的文件解压后,将dll文件,贝到ext下
修改php.ini,开启
[eAccelerator] zend_extension_ts="C:/php/ext/eaccelerator.dll" //路径根据实际情况而定 eaccelerator.shm_size="32" //根据系统内存来定,默认16M,可以改成64M eaccelerator.cache_dir="C:/php/temp" //前面创建的缓冲文件夹 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"
配置redis:
下载http://www.redis.cn/download.html
解压后有两个dll文件,全部拷贝到ext目录下。[我拷贝到ext,还提示找不到。最后拷贝到php.exe目录下才不再报错]。
修改php.ini
添加
"extension=php_igbinary.dll
extension=php_vld.dll"
重启apache,phpinfo();可以查看是否启动。
测试redis:
$redis = new Redis(); $redis->connect("192.168.0.110","6379"); //php客户端设置的ip及端口 //存储一个 值 $redis->set("say","Hello World"); echo $redis->get("say"); //应输出Hello World //存储多个值 $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));
