如果配置错误，需要安装需要的模块，直接yum一并安装依赖库

yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype
freetype-devel libxml2 libxml2-devel mysql pcre-devel
 
#注意：安装php7beta3的时候有几处配置不过去，需要yum一下，现在php-7.0.0RC1已经不用这样了。
yum -y install curl-devel
yum -y install libxslt-devel
 
#如果 configure: error: Cannot find OpenSSL's <evp.h>
su #切换root用户，安装
yum install openssl openssl-devel 
 
#错误：configure: error: Please reinstall the libcurl distribution -easy.h
should be in <curl-dir>/include/curl/
#解决：
yum install curl curl-devel 
 
 
#错误 configure: error: freetype.h not found.
#解决：yum install freetype-devel
 
 
#configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution
yum install libxslt-devel

测试

php7和php5性能分析比较

新建文件search_by_key.php

<?php
//time /usr/local/php5/bin/php search_by_key.php
$a = array();
    for($i=0;$i<600000;$i++){
        $a[$i] = $i;
        }  
 
    foreach($a as $i)
    {
        array_key_exists($i, $a);
    }
?>
