str_split 没有自动换行

2021-12-28 00:00:00 string split word-wrap php 拆分 自动换行

我正在寻找最快的解决方案，以拆分 一个字符串分成几部分，没有 自动换行.

I'm looking for the fastest solution, to split a string into parts, without 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");

推荐答案

你其实可以使用 wordwrap()，输入到 explode() 中，使用换行符 作为分隔符.explode() 将在 wordwrap() 产生的换行符上拆分字符串.

You actually can use wordwrap(), fed into explode(), using the newline character as the delimiter. explode() will split the string on newlines produced by wordwrap().

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

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

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"
}
