【问题描述】：

我需要类似的东西

preg_match((element1)(.*?)if-(数量:)([^0])-return-TRUE, $str);

但是(.*?) 毁了一切，因为他在从另一个元素中找到(Quantity:)([^0]) 之前跳过了每个(Quantity:)(0)，例如(item2) 旁边的(element1)

element1 random:random Quantity:0 element2 random:random Quantity:0 item1 random:random Quantity:0 item2 random:random Quantity:999强>

那么我怎么能说 php 对 (Quantity:)([^0]) 执行严格并返回 TRUE，但如果是 (Quantity:)(0) 返回 FALSE 而不是和我一起玩无限 regonising (Quantity:)(0) 作为 (.*?) 呢？

我找到了灵魂

preg_match('/14:200001438#8;5:100014065.*?availQuantity":(\d+)/', $str);

接下来我们检查(\d+)是否等于0或任何数字
