My website uses a virtual host in the Win environment. In fact, when choosing a host, you still have to know it well and don’t be fooled by some space providers. The so-called "no businessman without treachery" still has its meaning. Since we cannot believe that "there is no thief in the world", then we can only be more vigilant.
Everyone who buys space should know that when buying space on Taobao, those wretched handsome guys or kawaii girls always recommend their own space. How good is it? I asked whether I support this or that, what are its advantages, what are its features, and so on. (Recommended learning: PHP Programming from entry to proficiency)
If you ask him what the Internet speed is, he will say it is very fast, and then give you a case to try, but in fact you use After you install it, you will find that the speed is actually not that good; if you ask whether the space is stable, people will say it is very stable and how good the configuration is, but in reality, it often gives you a downtime to play with; the customer service is available 24 hours a day, but in reality, I have a service for you, please wait or it is being processed. So we have to test it ourselves, after all, it doesn’t feel very good to be fooled!
I didn’t understand what a php probe was at first? What does php probe do?
php probe is used to detect space, server operating status and PHP information. The probe can view server hard disk resources, memory usage, network card traffic, system load, server time and other information in real time.
Let me share how I use php probes to detect the server website space speed, performance, security functions, etc.
The specific steps are as follows:
1.Download a php probe from the Internet (just search for php probe online, about 24KB Left and right size)
2. After decompression, you will get three files. Just upload index.php and uenu.php to the root directory of the website.
3. When you open the space address, there will be some network conditions, PHP related, server parameters, server real-time data and a series of information, and then you can test and view them one by one. , compare with the data parameters given to you by the space provider to see if you have been fooled.
The above is the detailed content of How to use php probe. 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。

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。
