将这些结果拆分为数组

Question

我真的很难制作一些正则表达式来将：

Child Non Peak @ $10.75 USD <br/>
<input name="quan0" maxlength="1" size="1" class="star_N"/> <br>
Infant Non Peak @ $13.75 USD <br/>
<input name="quan1" maxlength="1" size="1" class="star_N"/> <br>
Adult Non Peak @ $13.75 USD <br/>
<input name="quan2" maxlength="1" size="1" class="star_N"/> <br>
Senior Non Peak @ $12.50 USD <br/>
<input name="quan3" maxlength="1" size="1" class="star_N"/> <br>
Member Adult Non Peak @ $12.75 USD <br/>
<input name="quan4" maxlength="1" size="1" class="star_N"/> <br>
Member Senior Non Peak @ $11.50 USD <br/>
<input name="quan5" maxlength="1" size="1" class="star_N"/> <br>
Member Child Non Peak @ $9.75 USD <br/>
<input name="quan6" maxlength="1" size="1" class="star_N"/> <br>

变成一个数组，就像

array (
 value: Child Non Peak @ $10.75 USD 
 price: 10.75

有人可以帮忙吗？我已经有了这段非常复杂的正则表达式，但它不适合目的。

preg_match_all('/class="t12">(?P<type>\w+)[\s@]*(?P<cost>\$[\d.]*)\s+USD(.*)name="(?P<input>quan\w+)"/msU',
               $output,
               $matches,
               PREG_SET_ORDER);

Answer 1

preg_match_all('/[\w ]* @ \$?([0-9]{1,}\.?[0-9]*) [A-Z]{2,3} ?/', $output, $matches, PREG_SET_ORDER);

print_r( $matches );

给出了下一个结果：

Array
(
    [0] => Array
        (
            [0] => Child Non Peak @ $10.75 USD 
            [1] => 10.75
        )
    [1] => Array
        (
            [0] => Infant Non Peak @ $13.75 USD 
            [1] => 13.75
        )
    [2] => Array
        (
            [0] => Adult Non Peak @ $13.75 USD 
            [1] => 13.75
        )
    [3] => Array
        (
            [0] => Senior Non Peak @ $12.50 USD 
            [1] => 12.50
        )
    [4] => Array
        (
            [0] => Member Adult Non Peak @ $12.75 USD 
            [1] => 12.75
        )
    [5] => Array
        (
            [0] => Member Senior Non Peak @ $11.50 USD 
            [1] => 11.50
        )
   [6] => Array
        (
            [0] => Member Child Non Peak @ $9.75 USD 
            [1] => 9.75
        )
)

Answer 2

([a-zA-Z ]+ @ \$(\d+\.\d{2}) USD) 应该会给你很好的结果

• [a-zA-Z ]+< /code> 是产品名称，
• @ 位于产品和价格之间
• \$(\d+\.\d{2}) 价格，group 捕获至少 1 位数字，后跟 .后跟 2 位数字
• USD 捕获最后一个空格和货币参考

Answer 3

使用像 DOMDocument 这样的 DOM 解析器来检查元素。

使用正则表达式解析 HTML 可能会导致意想不到的后果。
