php运行出现Call to undefined function curl_init()的解决方法_php技巧

curl_init

在网上下载了一个模拟登陆discuz论坛的php程序范例,试运行时出现“Call to undefined function curl_init”这个错误提示,没有定义的函数,也就是php还没打开对curl_init函数的支持。Google了一番终于解决了,方法如下:

系统环境,WIN2003 IIS6,PHP版本5.2.12
在装好PHP后,执行类似$ch = curl_init();这样的语句,出现Call to undefined function curl_init()的错误提示。

解决方法如下:

1、在php.ini中找到extension=php_curl.dll,去掉前面的,php.ini一般在c:\windows下面。

2、在php.ini中找到extension_dir = "ext",去掉前面的;,改为extension_dir = "C:\php5\ext"。
"C:\php5\ext"只是示例,即扩展指向的路径要对

3、php_curl.dll、libeay32.dll、ssleay32.dll、php5ts.dll都拷到system32下面去。

4、然后重启电脑,故障解决。

注意:在PHP的5.2.8版本中不知道什么原因,用这方法无法解决,换成了5.2.12才解决掉。

以windows下的php+apache为例。

  首先,打开php.ini,找到“extension=php_curl.dll”,然后去掉前面的“;”注释,重启apache即可。

  如果还出现此类问题,先检查php.ini的extension_dir值是哪个目录,在那个目录下检查有无php_curl.dll,没有的话请下载php_curl.dll,再把php目录中的libeay32.dll和ssleay32.dll拷到c:\windows\system32里面,重启apache,OK!

在Ubuntu 下运行php,总是提示Call to undefined function curl_init(),原因没有安转:php5-curl

与curl相关的内容见:http://packages.ubuntu.com/zh-cn/intrepid/php5-curl

CURL is a library for getting files from FTP, GOPHER, HTTP server.

PHP5 is an HTML-embedded scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dinamically generated pages quickly. This version of PHP5 was built with the Suhosin patch.

curl_init -- 初始化一个CURL会话

描述  

int curl_init ([string url])  

curl_init()函数将初始化一个新的会话,返回一个CURL句柄供curl_setopt(), curl_exec(),和 curl_close() 函数使用。如果可选参数被提供,那么CURLOPT_URL选项将被设置成这个参数的值。你可以使用curl_setopt()函数人工设置。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
