Some win host IIS does not support .htaccess files. What I mean here is not local. If you use apmserv server locally, you can use .htaccess files. If you use apmserv server environment to configure pseudo-static, you can see php pseudo-static (url rewrite mod_rewrite). (Written) This article is very detailed.
Here we mainly explain httpd.ini. Let’s not talk nonsense and just look at the effect~
Example: www.jb51.net/index.php
We want him to use www.jb51.net/index.html to directly access
www.jb51.net/newxx.php?=10 [ newxx.php is the news detailed page]
We make it pseudo-statically www.jb51.net/new-10.html
The implementation process is as follows: httpd.ini source file
[ISAPI_Rewrite]
# 3600 = 1 hour
# CacheClockRate 3600
RepeatLimit 32
# Protect httpd.ini and httpd.parse.errors files
# from accessing through HTTP
RewriteRule ^/httpd(?:.ini|.parse.errors).* [F,I,O]
RewriteRule /index.html /index.php
RewriteRule /new-([0-9] +).html$ /newxx.php?uid=$1 From the above example, we can see that RewriteRule /index.html /index.php converts index.php to index.html
RewriteRule /new-([0-9 ]+).html$ /newxx.php?uid=$1 Convert to new-10{This 10 is the value of id=}.html
It’s very simple. This kind of pseudo-static is basically supported by the space quotient of win host!

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。
