Question

When we enter a word in Google image search, a page is returned. This page contains many pictures with thumbnail view. I want to save the location URL of these images in my database (MySQL). I need to code this in PHP and I want to save URL of first 10 images. I am designing a dynamic page, I will pick these image URL addresses from database and will show these on my dynamic page.

I have already tried a lot and problem is my complete URL is not saved because it contains many invalid characters for MySQL. I have searched many sites and found different functions but I am still not clear about this: I am at failure in devising an idea how I can do this job. Can somebody give me some PHP code or a procedure how it could be done?

我建议你使用PHP sDOM Library。它非常强大,能够使任何OMA结构陷入瘫痪。引用其中一些例子,你可以轻易执行。

想法是,你研究谷歌归还的网页的超文本结构,并据此利用OM图书馆对具体标签进行分立。从我看到的情况来看,这些图像是作为<代码><ul>和<li>标签等组织的:

<ul class="rg_ul" data-pg="1" data-cnt="6">
    <li class="rg_li" data-row="1" style="width:216px;height:162px"></li>
    <li class="rg_li" style="width:231px;height:162px"></li>
    <li class="rg_li" style="width:218px;height:162px"></li>
    <li class="rg_li" style="width:216px;height:162px"></li>
    <li class="rg_li" style="width:216px;height:162px"></li>
    <li class="rg_li" style="width:217px;height:162px"></li>
</ul>

在每一栏目中,<代码><li> tag有附加标签,其中一栏为<a>。这一标签似乎有2个特性——“imgrefurl”和“imgurl”——可能给你所需要的形象。你们需要的这2个属性是你们探索的。

或者,在<代码>和t;img> tag within <li>中具有包含实际形象的“弧”特性。因此,你也可以这样做。请注意,双轨是你在搜索网页上看到的形象,而不是实际形象。

For some pointers to DOM, this method might be useful - http://www.php.net/manual/en/domelement.getelementsbytagname.php and http://www.php.net/manual/en/domelement.hasattribute.php - to read all <li> tags and then parse for the ones using class "rg_li".

I hope the above makes sense

可以通过http://php.net/manual/en/book.curl.php” rel=“nofollow”来做到这一点。 PHP曲线图书馆和PHP类别DOMDocument ,然后使用 Mysql或Mysqli libreries与数据库链接。 MySQL帮助见:。 MySQL Doc。
