str_split不带自动换行

Question

我在寻找最快解决方案，以split将字符串转换为零件，而不是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

实际上，你可以使用wordwrap()，送入explode()，使用换行符\n作为分隔符。 explode()将分割由wordwrap()生成的换行符的字符串。

$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" 
}
