PHP training belongs to an area of IT training. With the popularity of the Internet, PHP has also become extremely popular. However, many training institutions have various pitfalls, which makes many people who want to participate in training feel timid and do not know how to choose.
How to find a good PHP training institution
Recommended: "PHP Training"
1. A friend has tried the water and recommends it to you. This is the most believable. Trust your friends.
2. Join more QQ groups related to technology and listen to other people’s suggestions. nIf recommended by many people, it must be trustworthy.
3. Everything with the word "promotion" on Baidu is pending. First understand the difference between "Baidu promotion" and "Baidu snapshot".
4. Field inspection to see the professionalism of the teacher. Don’t be at a disadvantage by shopping around, don’t be lazy, talk in person, and feel the sincerity of the other party through the superficial glamor.
5. Don’t look at the benchmark, look at yourself. If someone enters the Fortune Global 500, it has nothing to do with you. See how the training institution protects your personal employment.
6. Read the employment contract line by line. There should be no overbearing clauses. You can request to change the contract on the spot.
7. The employment contract depends on the employment. Whether it is a guarantee or a recommendation, the difference is whether all guarantees have a time limit. That is, "limited time employment." If there is no time limit, it means "recommended employment." If employment is not limited, it means there is no guarantee. For example: I promise to give you 10 million, but I won’t say when I will give it to you. This item is the biggest loophole in the current training agreement, and many people have suffered greatly from this aspect. Many people still have no job after being recommended for 3 months and have no choice but to change careers.
8. Employment first, payment later. It's just a form of installment. If you can't find a job, you still need to repay the loan.

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。
