Pursue hard, just to be worthy of myself
Time flies, and before I know it, I have been struggling in Band of Brothers for more than two months. Looking back on the process of learning PHP in these two months, there are bitterness, sweetness, sourness, and spicyness, although the bitterness is more than the sourness. It's spicy, but I don't regret it, I will continue to move forward.
The very beginning of HTML made me realize my own shortcomings and what I didn’t do enough. I didn’t work hard enough, I was too confident, I didn’t have enough background, and I had a bad work and rest schedule. As a result, I struggled with learning HTML and other problems. There is a gap between classmates. The first stage test hit me hard, letting me know that if I don’t work hard, there will be no reward, I will let myself know that if I don’t work hard, I won’t improve, and I will let myself know that any laziness you commit is your own fault. , let yourself know that your efforts are not for others, but for yourself.
The first blow made me work hard for a long time, and I successfully completed the first phase of the project test and felt very good about myself. I know that hard work will definitely lead to progress, and hard work will definitely pay off. The first phase of the project was not done very quickly at the beginning, and there was still a big gap between me and the aunts in the class. I only knew what Brother Sheng taught me, and I had no idea about the development and the part I would complete in the project. Through the guidance of others, I finally came up with a general idea. Did it successfully. After handing in the project, when we thought back on the knowledge we had at the primary stage, we realized that it was all usable. You will have a deeper understanding that your efforts are directly proportional to your future salary.
I started learning Linux after the first phase of the project. I found that I had to memorize all the regular commands in the early stage. Compared with PHP, I understood less things. In addition, my usual work and rest time was a bit messy. I started to lose energy in class, so I fell into trouble. I often fall asleep in class. After I wake up, I realize that I have been pulled away by others. Alas, my laxity prevents me from discovering others and myself. Being lax has disrupted my work and rest. I know that Linux is very important. There is still time in the past. I will learn about it and go deeper into it in my future work.
The PHP advanced class has started. I am in a bad state. I want to change well and start the advanced class with all my heart. I will radiate all my passion in the advanced class. I will not doze off in class and complete the tasks with quality and quantity after class. I want to I will be worthy of my commitment to my parents, teachers, and brothers. Don’t give up, dare to pursue, and be willing to endure hardships, I can do it!

The above introduces the pursuit of hard work, just to be worthy of myself, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.

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。

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。

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。
