When I was learning JS before, I read JavaScript DOM Programming Art and JavaScript Advanced Programming. I feel that reading can help with learning and understanding. Are there any better books on PHP?

Watch the novice tutorial! Are there any examples?
PHP
has changed dramatically in the past five or six years, with the advent of composer (
PHP’s dependency management tool) and PSR (
PHP Standards Recommendations), the entire ecosystem and development of
PHP The model is becoming more mature and modern.

If you want to learn modern
PHP
Josh Lockhart’s Modern PHP.
In addition, for free resources on the Internet, it is recommended to read PHP The Right Way, the author is also

, I'm just kidding, don't take it seriously
Serious: In fact, the original title of the book is "PHP from Getting Started to Mastering", I have a copy of this book, I bought it a few years ago. I can lay the foundation for it, but after studying this book, I can only be considered familiar with it, not proficient.
Because this book was written a few years ago, and it still uses PHP5.2, so the namespace, composer and other features added to PHP later are not mentioned. And many functions in it are not mentioned. You need to read PHP Official manual
. PHP Official Manual is the first choice for getting started. It is recommended for novices to learn. If you want to improve, you don’t need to learn low-level PHP frameworks such as ThinkPHP. The correct solution is to learn mature frameworks such as YII2/Laravel.
As well as the PHP method mentioned above, here is the translated version of PHPHub, highly recommended!
Recommend "Learn PHP from Zero Basics". Of course, you need to have a basic knowledge of programming. It is more suitable to read the manual directly. PHP is more suitable! Or you can take a look at the novice tutorial on PHP
Gao Luofeng's "Details on PHP", http://www.lampbrother.net/ Their official website has some free video tutorials, which I thought were good.
An old driver recommended me to read the translated version of The Way of PHP
I think the official PHP documentation is very good.
I’m a newbie too haha

<p>I don’t know why Brotherhood’s “PHP in Detail” has been criticized. Personally, I think it’s pretty good. It explains the profound things in simple terms. It’s good to read if you’re just starting to learn. Some issues can be explained simply and clearly, but I still have to emphasize the need to code by hand. , it is a truth that true knowledge comes from practice</p>

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。
