如何使用PHP选择图像源
所以我有一些具有以下几种形式的图像:
<a href="" class="link-img" alt="">
<img editable="true" style="display: block; cursor: default;" class="main-image"
width="538" height="auto" src="src" alt="large image">
</a>
这样:
<a href="" class="link link-img">
<img src="src" style="width: 100%; display: block; cursor: pointer;" editable="true"
class="main-image imageLink" width="" height="auto" alt="">
</a>
所以我选择src映像的代码是:
$c = preg_replace('/<a href="(.+)" class="link link-img" alt="(.+)"><img src="(.+)"></a>/i'
,'<% link url="$1" caption="<img style=max-width:500px; src=$8 >" html="true" %>',$c);
我试了几次,但代码不起作用,如果有人有任何想法,我将不胜感激。
解决方案
尝试此方式从映像src="([^"]+)"
src
编辑:查看regex此处https://www.regex101.com/r/yF8tJ1/1
代码示例:
$re = "/src="([^"]+)"/";
$str = "<a href="" class="link-img" alt="">
<img editable="true" style="display: block; cursor: default;" class="main-image"
width="538" height="auto" src="src" alt="large image">
</a>
<a href="" class="link link-img">
<img src="src" style="width: 100%; display: block; cursor: pointer;" editable="true"
class="main-image imageLink" width="" height="auto" alt="">
</a>";
preg_match_all($re, $str, $matches);
