如何在第一次出现的东西上拆分字符串？

I know "explode" splits the string and turns it into an array for every occurrence. But how do I split on the first occurrence and keep everything after the first occurrence?

我知道“explode”会拆分字符串并将其转换为每次出现的数组。但是，如何在第一次出现时拆分并在第一次出现后保留所有内容？

Examples:

例子：

$split = explode('-', 'orange-yellow-red');
echo $split[1]; // output: "yellow"

^ I would like this to output: yellow-red

我希望这输出：黄红色

$split = explode('-', 'chocolate-vanilla-blueberry-red');
echo $split[1]; // output: "vanilla"

^ I would like this to output: vanilla-blueberry-red

我希望这输出：香草蓝莓红

5 个解决方案

#1

You can pass the limit as the third parameter of explode that will do the job.

您可以将限制作为将执行此任务的第三个爆炸参数传递。

$split = explode('-', 'orange-yellow-red',2);
echo $split[1]; //output yellow-red

#2

Have a look at the third parameter of explode:

看看爆炸的第三个参数：

$limit

$极限

If limit is set and positive, the returned array will contain a maximum of limit elements with the last element containing the rest of string.

如果设置了limit并且为正数，则返回的数组将包含最多限制元素，最后一个元素包含其余字符串。

If the limit parameter is negative, all components except the last -limit are returned.

如果limit参数为负，则返回除最后一个-limit之外的所有组件。

If the limit parameter is zero, then this is treated as 1.

如果limit参数为零，则将其视为1。

$a=explode('-','chocolate-vanilla-blueberry-red', 2);
echo $a[1]; // outputs vanilla-blueberry-red

#3

$split = explode('-', 'chocolate-vanilla-blueberry-red');
unset($split[0]);
echo implode('-', $split); # vanilla-blueberry-red

#4

A solution without a variable :

没有变量的解决方案：

strtok('orange-yellow-red', '-');
echo strtok(null);

#5

-1

a regular expression perhaps?

也许正则表达式？
