PHP specifies the length to split the string str_split function usage example

The example in this article describes the usage of str_split function in PHP to split strings with specified length. Share it with everyone for your reference, the details are as follows:

Example 1:

$str = 'abcdefgh';
$arr = str_split($str,2);

The running results are as follows:

}

Example 2:

$arr = str_split($str);
$i = 0;
$limit = 3;
$num = count($arr);
while($i <= $num-1){
  $temp = array();
  $for_countbu = ($num-$i) >= $limit ? $limit : $num - $i;
  for($j = 0; $j < $for_countbu; ++$j)
  {
    $temp[] = $arr[$i];
    ++$i;
  }
  $one = implode(&#39;&#39;,$temp);
  $result[] = $one;
}
print_r($result);
