php - 没有自动换行的 str_split

Question

我正在寻找最快的解决方案，到split一个字符串分成几部分，没有 word-wrap .

$strText = "The quick brown fox jumps over the lazy dog";

$arrSplit = str_split($strText, 12);

// result: array("The quick br","own fox jump","s over the l","azy dog");
// better: array("The quick","brown fox","jumps over the","lazy dog");

Answer 1

你实际上可以使用 wordwrap() , 被送入 explode()，使用换行符 \n 作为分隔符。 explode() 将在 wordwrap() 生成的换行符处拆分字符串。

$strText = "The quick brown fox jumps over the lazy dog";

// Wrap lines limited to 12 characters and break
// them into an array
$lines = explode("\n", wordwrap($strText, 12, "\n"));

var_dump($lines);
array(4) {
  [0]=>
  string(9) "The quick"
  [1]=>
  string(9) "brown fox"
  [2]=>
  string(10) "jumps over"
  [3]=>
  string(12) "the lazy dog"
}
