从html源获取数据所需的正则表达式模式

I'm reading html source of an online shop and I can find below information which shows stock availability for each SKU.

'{"sku-SV023435_B_M":8,"sku-SV023435_BL_M":10,"sku-SV023435_PU_M":11}'

I need to retrieve each SKU and it's quantity in an array.

Please help me which the PHP code.

Thanks

Edit: Here is the source link Source

I guess you want this:

$a = '{"sku-SV023435_B_M":8,"sku-SV023435_BL_M":10,"sku-SV023435_PU_M":11}';
$a = json_decode($a)
echo "<pre>";
print_r($a)
