The whole process, so to speak, was more surprising than surprising. And I felt the same feeling of vulnerability and ignorance I had when I first configured PHP on Windows...
First of all. . . For the first time, the PHP Team has separated into a Windows team. Windows downloads have also been moved to windows.php.net. A big improvement.
Secondly. . . The biggest surprise is that starting from PHP 5.3, there is no ISAPI support... You can see here: ISAPI support, do we need it?
I have never seen the PHP Team move so quickly. There is still a one-year transition period for PHP 4 to stop supporting. ISAPI says it will be gone... Well, I support this strategy. Since Microsoft has released IIS FastCGI support, then stop it. . . After all, in terms of stability, FastCGI is still better than ISAPI... It's just that I don't know about such a big thing... I'm really ignorant. An introduction to setting up PHP using FastCGI under IIS can be found here.
Moreover. . . I just installed it and did nothing. PEAR reported an error and could not be used -. -|||
Well, it’s not my fault. Regarding this error, the explanation is as follows:
Some users have reported that the windows builds of PHP 5.3 are not able to open the shipped go-pear.phar file.
As a workaround, users can run the distributed phar with php -d phar.require_hash=0 go-pear.phar or download and use the http://pear.php.net/go-pear non-pharred version.
Summary Let me share my feelings...
1. For IIS 5.1, 6.0, 7, please install Microsoft FastCGI first;
2. Without ISAPI support, for PHP 5.3, Installer and There is not much difference in zip; in comparison, I personally feel that the installer version has less stuff (the library is not missing, and there is no annoying phar version of PEAR), and it is more refreshing;
3. After the installation is completed, Change the date.timezone setting in php.ini, otherwise IIS will report a 500 error to you...
4. If you are installing the installer version and need PEAR, then do this: 1. Change http Download from ://pear.php.net/go-pear; 2. php go-pear.
If the zip version is installed, please execute php -d phar.require_hash=0 go-pear.phar , or install the non-phar version of PEAR according to the installer method above.

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。

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。

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。

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。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。
