PHP将字符串分为两部分

问题描述：

Note: I can't use break or next line functions as i am using FPDF

I am having a problem with php strings. I am having a string where i want to show atmost 12 characters in first row and remaining in second row. So basically i want to break string into two parts and assign to two variables so that i can print those two variables. I have tried following code :-

if($length > 12)
       {
         $first400 = substr($info['business_name'], 0, 12);
         $theRest = substr($info['business_name'], 11);
         $this->Cell(140,22,strtoupper($first400));
         $this->Ln();
         $this->Cell(140,22,strtoupper($theRest));
         $this->Ln();
       }

But using this I am getting as shown below :

Original String : The Best Hotel Ever
Output : 
The Best Hot
Tel Ever

It is breaking a word, i don't want to break the word, just check the length and if within 12 characters all the words are complete then print next word in next line. Like this :

Desired OutPut:
The Best 
Hotel Ever

Any suggestions ?

注意：我不能使用中断或下一行功能，因为我正在使用FPDF p> \ n

我遇到了php字符串的问题。我有一个字符串，我想在第一行显示最多12个字符，并保持在第二行。所以基本上我想把字符串分成两部分并分配给两个变量，以便我可以打印这两个变量。我尝试过以下代码： - p>

  if（$ length＆gt; 12）
 {
 $ first400 = substr（$ info ['business_name']，0,12  ）; 
 $ theRest = substr（$ info ['business_name']，11）; 
 $ this-＆gt; Cell（140,22，strtoupper（$ first400））; 
 $ this-＆gt; Ln（）  ; 
 $ this-＆gt; Cell（140,22，strtoupper（$ theRest））; 
 $ this-＆gt; Ln（）; 
} 
  code>  pre> 
 
 但是使用这个我得到如下所示： p> 
 
  原始字符串：有史以来最好的酒店
输出：
最好的热点
Tel Ever 
  code>  
 
 它打破了一个单词，我不想破坏单词，只需检查长度，如果在12个字符内所有单词都已完成，则在下一行打印下一个单词。 像这样： p> 
 
 
  Desired OutPut：
 Best 
Hotel Ever 
  code>  pre> 
 
 有任何建议吗？ p>  
  div>

I see no built-in function to do it, however you could explode on spaces, and re-build your string until the length with the next words get over 12, everything else going to the second part :

$string = 'The Best Hotel Ever';

$exp = explode(' ', $string);

if (strlen($exp[0]) < 12) {
  $tmp = $exp[0];
  $i = 1;
  while (strlen($tmp . ' ' . $exp[$i]) < 12) {
    $tmp .= " " . $exp[$i];
    $i++;
  }
  $array[0] = $tmp;
  while (isset($exp[$i])) {
    $array[1] .= ' ' . $exp[$i];
    $i++;
  }
  $array[1] = trim($array[1]);
} else {
  $array[0] = '';
  $array[1] = trim(implode (' ', $exp));
}

var_dump($array);

// Output : array(2) { [0]=> string(8) "The Best" [1]=> string(10) "Hotel Ever" }

// $string1 = 'The';
// array(2) { [0]=> string(3) "The" [1]=> string(0) "" } 

// $string2 = 'Thebesthotelever';
// array(2) { [0]=> string(0) "" [1]=> string(16) "Thebesthotelever" }

Im not too crash hot on PHP but it seems to be a simple case of which element of the string you are accessing is futher across from where you want to be:

Try:

if($length > 12)
       {
         $first400 = substr($info['business_name'], 0, 8); 
         $theRest = substr($info['business_name'], 11);
         $this->Cell(140,22,strtoupper($first400));
         $this->Ln();
         $this->Cell(140,22,strtoupper($theRest));
         $this->Ln();
    }
