爆炸串

Question

說我有一個字符串

$what = "1 x Book @ $20 32 x rock music cd @ $400 1 x shipping to india @ $10.5"; 

我想爆炸，使輸出

Array 
(
    [0] => 1 x Book @ $20 
    [1] => 32 x rock music cd @ $400 
    [2] => 1 x shipping to india @ $10.50 
) 

我想類似下面，但不知道要使用的正則表達式！

$items = preg_split('/[$????]/', $what); 

預先感謝

Answer 1

嘗試這種情況：

$str = '1 x Book @ $20 32 x rock music cd @ $400 1 x shipping to india @ $10.5'; 
preg_match_all('/(?P<match>\d+\s+x\s+[\w\s]+\s+@\s+\$[\d\.]+)/',$str,$match); 

echo "<pre>"; 
print_r($match['match']); 

輸出：

Array 
(
    [0] => 1 x Book @ $20 
    [1] => 32 x rock music cd @ $400 
    [2] => 1 x shipping to india @ $10.5 
) 

另一種解決方案：

根據Dream Eater的評論：更小的寫法：（。*？\ $ \ d +）\ s。 - Dream Eater 3分鐘前

我剛剛在最後加了*，它工作正常。

$str = '1 x Book @ $20 32 x rock music cd @ $400 1 x shipping to india @ $10.5'; 
preg_match_all('/(.*?\$\d+)\s*/',$str,$match); 

echo "<pre>"; 
print_r($match);
