【php100 Selected Translation】Rasmus Lerdorf may be the most famous computer expert in Greenland. He created the PHP scripting language in 1995 and successfully applied it to his website. Under his cultivation, PHP has become Becoming a powerful, fully mature language, there are currently millions of PHP application cases around the world.
PHP founder Rasmus Lerdorf
Linux Format magazine conducted an exclusive interview with Rasmus Lerdorf to reveal the details for us Rasmus Lerdorf's current position in the PHP community, and how he made decisions in the early days, have allowed PHP to achieve the great success it has today.
Linux Format (hereinafter referred to as LXF): How much PHP development are you currently involved in?
Rasmus Lerdorf (hereinafter referred to as RL): It’s much less common now than 10 or 15 years ago, but I still read the mailing list every day, discuss features and occasionally fix bugs. I'm personally more interested in security and performance related issues.
LXF: What is the organizational structure of the PHP team? It doesn’t seem clear right now…
RL: There’s no structure!
LXF: So who makes the final decision?
RL: Let’s do it together! We have a completely open mailing list internally, anyone can subscribe to it, read it, comment on it, etc. I've always insisted on keeping it transparent, anyone can flip through the mailing list, and if disagreements arise, who implements it first Whoever wins usually wins.
LXF: Do you feel any pressure as the final arbiter?
RL: Of course there is pressure. I always try to downplay that role because I don't want to have the final say on too many things, I want the project to be self-sustaining, I want it to be self-propelled, if I'm stuck in a decision-maker role making every decision , that is also unrealistic.
To be honest, there are some things that I don’t know enough about, such as Sybase. I have never used Sybase, so how can I make the right decision about Sybase extensions? At this time, members of the team who are familiar with Sybase need to make the decision.
LXF: Has the development of PHP 6 slowed down? It has been in development for two and a half years...
RL: No decision to slow down

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)”。

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。
