PHP - 分割字符串后的数组X字符没有限制的切割字

Question

我想分割一个字符串后，将x个字符，并将其放在数组中。但是如果x在一个词的中间，我不需要切词。我期望的是分裂为劣势这个词。

我尝试这样做：

CODE

$string = "Helllooooo I'mmm <strong>theeeeee</strong> <em> woooooorrd</em> theeee loooonnngessttt"; 
$desired_width = 24; 

$str = wordwrap($string, $desired_width, "\n"); 

var_dump($str); 
die; 

输出

string 'Helllooooo I'mmm 
<strong>theeeeee</strong> 
<em> woooooorrd</em> 
theeee loooonnngessttt' (length=86) 

如何把它放在阵列？还有另一种方法可以做到吗？这和爆炸（）之间的混合？谢谢 ！

Answer 1

$string = "Helllooooo I'mmm <strong>theeeeee</strong> <em> woooooorrd</em> theeee loooonnngessttt"; 
$desired_width = 24; 

$str = wordwrap($string, $desired_width, "\n"); 
$arr = explode("\n", $str); 
var_dump($arr); 
die; 

Answer 2

试试这个

$string = "Helllooooo I'mmm <strong>theeeeee</strong> <em> woooooorrd</em> theeee loooonnngessttt"; 
$desired_width = 24; 

$str = wordwrap($string, $desired_width, "***"); 
$str = explode("***",$str); 
var_dump($str); 
die; 

输出

array(4) { 
    [0]=> 
    string(16) "Helllooooo I'mmm" 
    [1]=> 
    string(25) "<strong>theeeeee</strong>" 
    [2]=> 
    string(20) "<em> woooooorrd</em>" 
    [3]=> 
    string(22) "theeee loooonnngessttt" 
}
