php - str_split without word-wrap

Question

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");

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"
}
