There are many people learning PHP at present. Many friends who are doing PHP training will always ask this question during their studies: What is the PHP connection function implode?
php can split string into arrays, and at the same time, you can also connect arrays into strings. To be precise, you can connect array elements into strings. With these two functions We can freely convert between arrays and strings. Let’s look at the example in the text.
implode() connection function:
This function implements connecting array elements into strings. Before connecting, we need to give it two parameters, one is The connector one is the array to be connected
Note that it is a one-dimensional array Oh, multi-dimensional editor rarely uses it, but you can try it.
Example:
<?php $array = array('a' => 1, 'b'=>2, 'c'=>3, 'd'=>4); $string = implode("-",$array) echo $string; //==== 结果就是:1-2-3-4; ?>
##explode() Split function:
This function The function is to split the string into an array. We still give it two parameters, one is the delimiter and the other is the string to be split Note that this delimiter exists in the string, we Still using the above results as an example
The code is as follows:
<?php $string = "1-2-3-4"; $array = explode("-",$string); echo "<pre class="brush:php;toolbar:false">"; print_r($array); //==== 结果就是上面例子定义的数组喽,这里小编就不写出来了 ?>

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”。

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。

在PHP中,我们经常需要将数组中的元素组合成一个字符串。而这个时候,implode()函数就派上用场了。implode()函数能够将数组中的元素转换成字符串,并将它们连接起来,从而产生一个完整的字符串。这篇文章将会介绍如何在PHP中使用implode()函数将数组转换为字符串。一、implode()函数的基本使用方法implode()函数有两个参数。第一个参

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。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。

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)”。

转化方法:1、使用“mb_substr($url,stripos($url,"?")+1)”获取url的参数部分;2、使用“parse_str("参数部分",$arr)”将参数解析到变量中,并传入指定数组中,变量名转为键名,变量值转为键值。
