本地WAPM环境,php.ini有打开allow_url_fopen = On
write.php
$fp = fsockopen('localhost',80,&$errno,&$errstr,5);
if(!$fp)
{
echo "$errstr ($errno)
\n";
}
else
{
fputs($fp,"GET / HTTP/1.0\nHost: http://localhost/1.php");
fclose($fp);
}
?>
在localhost根目录下存在1.php,但测试运行write.php后,
发现1.php并没有被执行,单独执行1.php是可以运行
请问为什么?
试过把http://localhsot/1.php改为1.php也不行;过程中没提示无法创建套链接

$fp = fsockopen('localhost', 80, $errno, $errstr, 5); if(!$fp) { echo "$errstr ($errno)<br />\n"; }else { fputs($fp,"GET /1.php HTTP/1.0\r\nHost: localhost\r\nConnection: Close\r\n\r\n"); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp);}
$fp = fsockopen('localhost', 80, $errno, $errstr, 5); if(!$fp) { echo "$errstr ($errno)<br />\n"; }else { fputs($fp,"GET /1.php HTTP/1.0\r\nHost: localhost\r\nConnection: Close\r\n\r\n"); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp);}
在本地测试的时候,其他电脑访问我这台电脑,用ip的方式可以正常执行,即假设我测试ip为192.168.10.60,
其他电脑使用http://192.168.10.60/write.php可以正常;
但把程序放到服务器上去,服务器ip假设为192.168.10.3,
运行却无法执行,需要把
连接方式变成192.168.10.3,然后fputs的时候,要写绝对路径才可以……这是啥情况?
这不是很正常吗?
你放到192.168.10.3
就不是localhost了,当然要用绝对ip访问,有什么问题?
这不是很正常吗?
两点不正常
1、以我本机为测试主机时,其他机器访问我本机,在使用localhost的时候可以正常运行;而把程序放到服务器时,我本机访问服务器就不行;
2、我说的写绝对路径是不是指fsocketopen建立链接时写,而是譬如当程序是放在web目录下的ca/ma目录下时,下面的
fwrite的路径要写192.168.10.3/ca/ma/1.php,即便我write程序与1.php程序是放置在同一目录下也需要这样。
但同样的这个现象我放在本地时,用其他电脑访问本地却正常。本地是win系统,服务器是linux系统,然道是因为OS的关系?
1、程序是在你的机器上运行的,所以用 localhost 能访问到是正常的,用你机器的 ip 能访问到也是正常的
2、当程序搬迁至服务器上时,按理说用 localhost 也是能访问到的,但由于服务器的特殊性可能没有做 127.0.0.1 到 localhost 的映射,那么就访问不到了。

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
