The solution to the problem that PHP cannot be accessed from the external network when setting up the External access requests are forwarded to the local Web service; 3. Dial-up Internet access needs to be bound to a static IP or use dynamic DNS; 4. Check whether there are other programs on the machine listening to port 80. These programs need to be stopped or transferred to other ports. to avoid conflicts.
The operating system for this tutorial: Windows XP system, php8.1.3 version, Dell G3 computer.
After setting up a PHP environment on Windows XP, the inability to access the external network may be due to the following reasons:
1. Firewall:
The XP system has the firewall enabled by default, and port 80 needs to be opened. You can enter "Control Panel" -> "Windows Firewall" -> "Advanced Settings" and add inbound rules to allow access to the port.
2. Network settings:
You need to set up port forwarding in your own router or offline test server to forward external access requests to the local Web service.
3. Dynamic IP:
If you are using dial-up Internet access, it will often be Assign different dynamic IPs. If this happens, you need to bind a static IP or use dynamic DNS to solve it.
4. Port occupation:
You also need to check whether there are other programs on the machine listening to port 80. You need to stop these programs or transfer them to other ports. avoid confict.
In addition, PHP itself may also malfunction, resulting in inaccessibility, which may include syntax errors, code execution failures and other problems. The PHP error log and application log need to be checked to determine the specific cause of the problem so that it can be repaired and resolved.
The above is the detailed content of How to solve the problem that PHP cannot be accessed from the external network in XP system. For more information, please follow other related articles on the PHP Chinese website!

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。
