如何在PHP中将数字与数字分开

问题描述：

I have string as following:

$str = "Q1-Q4,A3-A6,S9-S11";

Can someone tell me how to split the above text in PHP so that I get following as output:

Q1,Q2,Q3,Q4,A3,A4,A5,A6,S9,S10,S11

我的字符串如下： p>

  $ str =“  Q1-Q4，A3-A6，S9-S11“; 
  code>  pre> 
 
 有人能告诉我如何在PHP中拆分上述文本，以便我得到以下输出：   p> 
 
 
 
  Q1，Q2，Q3，Q4，A3，A4，A5，A6，S9，S10，S11  p> 
  blockquote>

This should get you going. This separates the sequences, adds in extra items and returns all of this as an array you can conveniently use.

$str = "Q1-Q4,A3-A6,S9-S11";

$ranges = explode (',', $str);
$output = [];

foreach ($ranges as $range) {

    $items = explode ('-', $range );
    $arr = [];
    $fillin = [];

    $letter = preg_replace('/[^A-Z]/', '', $items[0]);
    $first  = preg_replace('/[^0-9]/', '', $items[0]);
    $last   = preg_replace('/[^0-9]/', '', end($items));


    for($i = $first; $i-1 < $last; $i++) {
        $fillin[] = $letter . $i;
    }

    $output[]  = $fillin;

}

var_dump( $output );
exit;

You will want to split the string using a regular expression, preg_split will be the ideal function to use in this case:

$str = "Q1-Q4,A3-A6,S9-S11";
$temp = preg_split('/[-,]/',$str);
print_r($temp);

Hope this helps,
