HomeBackend DevelopmentPHP Tutorial源码编译安装 PHP5.5.0,解决curl_exec访问HTTPS返回502错误的问题

        最近碰到一个奇怪的问题, PHP使用 curl_exec 访问 HTTPS 网页时, 返回502错误, 访问HTTP网页时没有问题,  用   echo   phpinfo() ;  查看, 支持openssl, 支持curl, 网上找了好多资料, 都没解决。


[root@www ~]# php -VFailed loading /usr/local/zend/ZendOptimizer.so:  /usr/local/zend/ZendOptimizer.so: undefined symbol: zend_throw_exception_internalPHP Warning:  PHP Startup: memcache: Unable to initialize moduleModule compiled with module API=20060613PHP    compiled with module API=20090626These options need to match in Unknown on line 0PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/openssl.so' - /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/openssl.so: undefined symbol: zend_parse_parameters_none in Unknown on line 0

用 #php  -V 查看, 提示  openssl.so  加载失败, 看来 肯定与openssl库有关。  重新安装了openssl库, 问题依旧。 原因是openssl库用到了 zend, 看上面的提示, 显示zend库也报错。 要处理估计还得重新安装zend库。 麻烦, 算了, 不让直接用源码编译一次 php, 说干就干吧。

       

下载了 PHP 5.5.0.tar.gz

安装过程中可能会碰到一些错误, 下面是我安装碰到的,环境不一样, 每台机器碰到的问题也会不一样。


1、 碰到错误  xpm.h not found

# yum  install libXpm-devel //注意x为大写
# yum  install libXext-devel //注意x为大写

2、碰到错误  gmp.h not found

#yum install gmp

#yum install gmp-devel

3、碰到错误 error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing. This should not happen

#yum install libc-client-devel

4、碰到错误  error: Unable to detect ICU prefix or /usr/bin/icu-config failed

#yum   install  libicu*

#yum   install   icu*

5、碰到错误  error: ODBC header file '/usr/include/sqlext.h' not found

#yum install unixODBC-devel

6、碰到错误   error: Cannot find pspell

#yum install aspell-devel

7、碰到错误    error: Can not find recode.h anywhere under /usr /usr/local /usr /opt.

#yum install recode

#yum install recode-devel

8、碰到错误  error: Could not find net-snmp-config binary

#yum install net-snmp-devel

9、碰到错误   error: Cannot find libtidy

#yum install libtidy-devel

php 安装完毕了 , 测试 了一下 php 页面, 问题依旧, 最终仔细看了一下,   phpinfo() 函数显示的版本是  5.2.17,  而我安装的是  5.5.0, 显然 nginx 服务器使用的还是

老的 php, 没有启用我最新编译安装的 php,  查找了一下, 老的 php 的目录是   /usr/local/bin/php,  而我新安装的php目录是  /usr/bin/php


为何不用最新的php呢, 显然与  环境变量PATH有关 , 执行命令  env  , 看到

PATH=/usr/local/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

我们可以修改  /etc/profile 文件 , 把文件最后一行 :


export PATH=/usr/local/mysql/bin:$PATH

修改为

export PATH=/usr/local/mysql/bin:/usr/bin:$PATH


然后

# cd /etc

#  source  profile   重新加载 profile 文件

最后再测试  php 文件,  curl_exec 可以访问 https 文件, 并取到数据了。

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
