php - 如何使用php从html中获取图像名称

Question

使用 php 获取所有图像标签

$html='<a herf="http://www.google.com">test</a></br>
       <p><img src="./../../src/image1.png"/></p>
       <a href="example.mpeg" title="Download movie">film name</a>
       <img border="0" src="/images/image1.jpg" alt="Image" />
       <img border="0" src="/images/image2.jpg" alt="Image"/>
       <img border="0" src="/images/image3.jpg" />';

preg_match_all('/<img[^>]+>/i',$html, $imageTags);  
$string=join(PHP_EOL,$imageTags[0]);
// echo '<xmp>'. $string .'</xmp>';

然后如何从这个图像标签中获取图像名称？比如，image1.jpg

这样试试，

$html='<a herf="http://www.google.com">test</a></br>
   <p><img src="./../../src/image1.png"/></p>
   <a href="example.mpeg" title="Download movie">film name</a>
   <img border="0" src="/images/image1.jpg" alt="Image" />
   <img border="0" src="/images/image2.jpg" alt="Image"/>
   <img border="0" src="/images/image3.jpg" />';


preg_match_all('/<img.+src=[\'"](?P<src>.+?)[\'"].*>/i', $html, $src);                
$srcArray = array_pop($src);

foreach($srcArray as $src ){
    $imgName=explode('/',$src); 
    $fileName[]=end($imgName);      
}
print_r($fileName);
