5. The types and calling methods of php functions are revealed
Introduction: In PHP, the use of functions is still very flexible, but no matter what, functions, in the final analysis, are still a process. At the same time, there must be a return value so that users can perceive its existence and its value! Therefore, a function is always used as a value. Therefore, it cannot appear on the left side of the equal sign '='. This is the biggest difference between functions and language structures. For example, we often say: echo() and list() are a language structure, not a function, although they look like functions, because they can be placed on the left side of the equal sign and can accept assignment. But functions don't work. I hope this article will give you a deeper understanding of functions~~

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”。

List操作//从list头部插入一个值。$ret=$redis->lPush('city','guangzhou');//从list尾部插入一个值。$ret=$redis->rPush('city','guangzhou');//获取列表指定区间中的元素。0表示列表第一个元素,-1表示最后一个元素,-2表示倒数第二个元素。$ret=$redis->l

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)”。

1:JSONArray转ListJSONArray字符串转List//初始化JSONArrayJSONArrayarray=newJSONArray();array.add(0,"a");array.add(1,"b");array.add(2,"c");Listlist=JSONObject.parseArray(array.toJSONString(),String.class);System.out.println(list.to

去除方法:1、使用substr_replace()函数将首位数字替换为空字符串即可,语法“substr_replace($num,"",0,1)”;2、用substr截取从第二位数字开始的全部字符即可,语法“substr($num,1)”。

php去掉数组键值的方法:1、使用“array_keys($array)”语句,可去掉全部键值,返回包含全部键名的数组;2、使用“array_splice($array,$start,$length)”语句,可去掉指定位置的一个或多个键值。
