公司写一个抛xml文档的程序 抛送url 用如下代码
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://".$this->IP.$this->URL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $this->PARAMETER );
$ret = curl_exec($ch);
curl_close ($ch);
这段代码所有参数我看了没有问题
但curl_exec() 返回时false值
我查了下百度说要开启 extension=php_curl.dll 这个动态库
----
请问这个动态库是不是只有在windows下才有。我公司的环境是php 5.3.5 ,linux 环境, 我查了下公司php.ini没有这个选项。
请问在linux下 如何使用这个函数。要如何配置php.ino
回复讨论(解决方案)
linux下php扩展curl的安装
需要编译进去,具体方法可以网上查阅一下。
phpinfo(); 看下curl 是否开启了。
.dll 是windows的动态链接库。
linux下是需要 .so扩展。
search一下吧,不少教程
curl_exec() 返回 false 值
表示连接 "http://".$this->IP.$this->URL 失败
请检查 url 真实可用
如果是 curl 扩展没有加载,则会报函数未定义
请问linux下如何查看 curl是否可用?
$ch = curl_init();
不报错
echo $ch;
输出 Resource id #...
就表示 curl 可用
专业一点就是
if(! function_exists('curl_init')) die 'curl 不可用';
我看到公司有curl.so 这个文件 。他的路径是:/usr/lib64/php/modules/curl.so
我在php.ini 中 加入extension=/usr/lib64/php/modules/curl.so 是否正确
--测试下 。还是不成功
"http://".$this->IP.$this->URL);
这个地址打印出来。
这个地址有效么?
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://".$this->IP.$this->URL); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $this->PARAMETER ); $ret = curl_exec($ch); // 检查是否有错误发生 if( curl_errno ( $ch )) { echo 'Curl error: ' . curl_error ( $ch ); } curl_close ($ch);
看看提示什么。
首先你应该从几个问题入手:
1)curl扩展是否开启,查看#7
2)curl的url是否正确
公司 curl.so文件都已经配置好。原因是这台服务器没有做连接外网的设置 谢谢 。已经调通了

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.
