你好！我有几个SQL语句，我需要拆分它们，我需要在语句中出现的第一个图像标记，我有它的代码来拆分它，但问题是所有不同的引号。有没有办法把它拿出来？
我现在的代码：
$array = array('INSERT INTO ba793_content(`id`,`asset_id`,`title`,`alias`,`introtext`,`fulltext`,`state`,`catid`,`created`,`created_by`,`created_by_alias`,`modified`,`modified_by`,`checked_out`,`checked_out_time`,`publish_up`,`publish_down`,`images`,`urls`,`attribs`,`access`,`hits`,`metadata`) VALUES( 120333,139,'Champ Cars 2007','champ-cars-2007','<table style=width: 429px; height: 74px height=74 width=429 border=0><tbody><tr><td><img title=champcar_logo_2007.jpg style=width: 200px; height: 79px height=79 alt=champcar_logo_2007.jpg hspace=5 src=images/stories/Store/champcar_logo_2007.jpg width=200 align=left vspace=5 border=0 /></td><td><div align=justify>Exclusieve toegangskaarten alleen hier te koop!

我在数组中有一些语句：

我只想要
<img style=margin: 0px; width: 200px; height: 124px; border: 0px solid #000000; float: left; src=images/stories/Nieuws/helmen.jpg alt=helmen.jpg title=helmen.jpg height=124 width=200 />
我现在得到的是错误，因为引号不会像正确的字符串，有人知道这样做吗？
答案 0 :(得分：1)
解析SQL并非易事。 （这也不难。）如果这是一次性工作，你可能会拿出一些正则表达式来取出你想要的东西。否则你需要使用解析器。
正则表达式/<img[^>]+>/将提取图片代码。它会在各种边缘情况下失败，因此不要依赖于此并验证输出。而你不需要PHP：
egrep -o '<img[^>]+>' < old_db.sql
这真的把车推到马前。为什么不使用专门用于工作的工具：Mysql？运行插入，然后查询数据。完成。如果你没有方便的mysql，请尝试sqlite。它看起来应该能够读取您的SQL。
