PHP is a very popular web development language that supports dynamic content development running on a web server. After you install PHP, you may encounter a problem, that is, PHP information cannot be displayed correctly when using the phpinfo() function. This problem can be due to many factors, and this article will cover ways to fix it.
- Check whether the PHP installation directory is correct
When you use the phpinfo() function, it will find the PHP installation directory. If the PHP installation directory is not set correctly, you will not be able to display PHP information correctly. In this case, you need to confirm that the PHP installation directory is correct. You can view it by running the phpinfo() function. If the output information is not what you expect, it is recommended to search for the PHP.ini file on the server and check whether the PHP installation directory is correct.
- Check whether the phpinfo() function is disabled
Some server security policies will disable the phpinfo() function. Disabling this function can prevent hackers from obtaining sensitive information of the server through this function. Therefore, in some cases, the phpinfo() function may be disabled due to security policy issues. You can try using other PHP functions to test whether the server is working properly.
- Check if the PHP version is correct
PHP is a rapidly evolving language, and new versions will contain many updates and improvements. If the PHP version you are using is too low, the phpinfo() function may not be able to display PHP information correctly. Therefore, it is recommended to use the latest version of PHP to ensure that the phpinfo() function works properly.
- Check Apache or Nginx configuration
In some cases, the configuration of Apache or Nginx may affect the working of the phpinfo() function. Checking whether Apache or Nginx is configured correctly is a very important step to solve this problem. Confirm that the PHP configuration is correct and check for any errors or issues in the Apache or Nginx configuration.
- Check that PHP extensions and libraries are correct
PHP and many extensions require support from other libraries and modules to work properly. If PHP does not have the correct extensions and libraries, the phpinfo() function will not be able to obtain and display PHP information correctly. Therefore, you need to make sure that PHP extensions and libraries are installed correctly.
Summary:
In web development, PHP is very important. When using the phpinfo() function, you will find that PHP information cannot be displayed normally. This problem may be caused by factors such as the PHP installation directory, PHP version, Apache or Nginx configuration, PHP extensions and libraries, etc. By finding and solving the above problems, you can make the phpinfo() function work properly and play a better role in web development.

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。

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,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

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。
