将字符串切成碎片而不会破坏文字。

I have a string:

我有一个字符串：

$str = 'Hello World, Welcome World, Bye World';

I want to cut above string into pieces. Each piece should be of 10 characters. If a word is going to be cut, then move that word to next line.

我想把上面的字符串切成碎片。每件应该是10个字符。如果要剪切一个单词，则将该单词移动到下一行。

For Example:

例如：

$output = array();

$output[0] = 'Hello ';
$output[1] = 'World, ';
$output[2] = 'Welcome ';
$output[3] = 'World, Bye'; 
$output[4] = 'World';

Is there a shortest way without so many if else and loops.

没有那么多if else和循环是否有最短路径。

Thanks

谢谢

Use wordwrap. By default it wraps whole words and does not cut them into pieces.

使用wordwrap。默认情况下，它会包装整个单词，而不会将它们分成几部分。

echo wordwrap('Hello World, Welcome World, Bye World', 10);

If you want an array, explode afterwards:

如果你想要一个数组，之后会爆炸：

print_r(explode("\n", wordwrap('Hello World, Welcome World, Bye World', 10)));

#2

string test = 'Hello World, Welcome World, Bye World';
string[] splited = test.Split(' ');
foreach (string str in s.Split(splited))
{
Console.WriteLine(str);
}

Note: Its written in C#, I hope it will give you an Idea.

注意：它是用C＃编写的，我希望它会给你一个想法。

Although not exactly the answer, some similar problem is like this:

虽然不完全是答案，但是类似的问题是这样的：

You have a long string, you want to break that string into chunks. You prefer not to break words, but words can be broken if word is very long.

你有一个很长的字符串，你想把这个字符串分成几个块。你不想打破单词，但如果单词很长，单词就可以被打破。

$string = "Hello I am a sentence but I have verylongwordthat I can split";

You will split the words in this sentence if word is very long, like this:

如果单词很长，你会在这句话中拆分单词，如下所示：

$pieces = explode(" ",$string);
$textArray=array();
foreach ($pieces as $p) {
    $textArray= array_merge($textArray, str_split($p, 10));
}
$stringNew=implode(" ",$textArray);

output:

输出：

"Hello I am a sentence but I have verylongwo rdthat I can split"
