php比较坑的地方就是实现同样的目的,可以使用超级多种手段。比如(file_get_contents和fopen以及现在提到的curl以及fsockopen当然还有socket)这对于一个经验少的程序员来说,确实比较难选。、

所以很多情况下,我们需要比较。搜索一下网上不负责任的资源,做一个预测。然后亲自比较权衡一下。

下面是摘抄的:

function curlRequest($url, $isPost = false, $param = array(), $cookie = null, $header = null, $referer = "", $timeout = 60) {        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $url);        if (is_array($header) && !empty($header)) { //设置header            $set_head = array();            foreach ($header as $k => $v) {                $set_head[] = "$k:$v";            }            curl_setopt($ch, CURLOPT_HTTPHEADER, $set_head);        } else {            curl_setopt($ch, CURLOPT_HEADER, 0);        }        if ($isPost === true) {            curl_setopt($ch, CURLOPT_POST, $isPost);            curl_setopt($ch, CURLOPT_POSTFIELDS, $param);        }        if (!empty($cookie)) {            if (is_array($cookie)) {                $cookies = implode(';', $cookie);            } else {                $cookies = $cookie;            }            curl_setopt($ch, CURLOPT_COOKIE, $cookies);        }        if (!empty($referer)) {            curl_setopt($ch, CURLOPT_REFERER, $referer);        }        if( $timeout > 0 ) {            curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);        }        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);        $ret = curl_exec($ch);        if (curl_errno($ch)) {            $ret = '';        }        curl_close($ch);        return $ret;    }

一般的过程,我们不会用到那么复杂:

<?php    $startTime = microtime(true);    $url = "http://api.k780.com:88/?app=weather.today&weaid=1&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=xml";    for($i = 0 ; $i < 2; $i++){        $handle = curl_init($url);        //$defaultHeader = array('Accept-encoding: gzip, default');        curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);        //curl_setopt($handle, CURLOPT_HTTPHEADER, $defaultHeader);        curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 10);        curl_setopt($handle, CURLOPT_TIMEOUT, 10);        $xml = curl_exec($handle);        if($i % 10 == 0){            echo ".";        }        curl_close($handle);    }    $endTime = microtime(true);    $total = $endTime - $startTime;    echo $total;    echo curl_error($handle);?>
Copy after login

需要说明的是:curl在控制台是不能运行的,比如php xxx.php params_1,它需要服务器。

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,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
