来源：互联网发布：centos 7.3 输入中文编辑：程序博客网时间：2024/04/24 17:50

安装环境centos 5.8 64位

1、下载并解压php7

2、先安装依赖包。

yum install systemtap systemtap-sdt-devel bzip2-devel.x86_64 gdbm-devel db4-devel openldap-devel readline-devel libedit-devel

3、创建安装目录

mkdir /home/work/app/php7

4、./configure --prefix=/home/work/app/php7 --with-config-file-path=/home/work/app/php7/etc --enable-bcmath --enable-calendar --with-pdo-mysql -enable-exif --enable-ftp --enable-gd-native-ttf --enable-mbregex --with-mysql-sock --enable-mbstring --enable-shmop --enable-soap --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --enable-zip --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-jpeg-dir --with-kerberos= --with-libedit --with-mhash --with-openssl --with-png-dir --with-xmlrpc --with-zlib --with-bz2 --disable-debug --enable-fpm --with-curl --with-xsl --with-ldap --with-ldap-sasl --with-mysqli=mysqlnd --with-mysql=mysqlnd --with-pdo-mysql=mysqlnd --enable-pcntl --enable-dtrace --enable-zend-signals

5、make & make install

测试了性能，针对php7主php5.4

分别运行100万次hash函数

list($sec,$mis) = explode(' ',microtime());for($i = 0;$i<1000000;$i++){        myHash($i);}function myHash($p){        $md5Str = md5(mt_rand(1000,9999)+$p);        $seed = 32;        $hash = 0;        $bitStr = substr($md5Str,0,8);        for($j = 0;$j < 8;$j++){                $hash = $hash*$seed+ord($bitStr[$j]);        }        return $hash & 0x7FFFFFFF;}list($sec2,$mis2) = explode(' ',microtime());

php7性能确实为php5.4的两倍

php7结果1秒：

0.47782200,1434167189
0.49571300,1434167190

php5.4为2.1秒

0.93335000,1434167282
0.81659100,1434167284
