自己想做一个相册样式的文章样式，于是在google一下，找了一些代码，于是自己动手稍稍改造了一下，放在while循环里就可以截取文章中的图片了~~
实在代码如下
<code>
global $post, $posts;
$post_leyaepimg = 0;
ob_start();
ob_end_clean();
preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
$post_leyaepimg = count($matches[0]);
if ( $post_leyaepimg > 0 ) {
for ( $i=0; $i < $post_leyaepimg ; $i++ ) {
echo $matches[0][$i];
};
};
</code>
global $post, $posts;
$post_leyaepimg = 0;
ob_start();
ob_end_clean();
preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
$post_leyaepimg = count($matches[0]);
if ( $post_leyaepimg > 0 ) {
for ( $i=0; $i < $post_leyaepimg ; $i++ ) {
echo $matches[0][$i];
};
};
</code>
如果配合TimThumb那就更好了，现在我又遇到了一个问题，上面输出的都是img标签，但是我想要得到img标签中的src地址，那我就不知道如何是好了~~
在google上搜索了一番~找到了一句，但还没有尝试一下~
<code>
$str = '<img border="0" src=\'/images/image.jpg\' alt="Image" width="100" height="100"/>';
preg_match('/(src=["\'](.*?)["\'])/', $str, $match); //find src="X" or src='X'
$split = preg_split('/["\']/', $match[0]); // split by quotes
$src = $split[1]; // X between quotes
echo $src;
//Other regexp's can be used to determine if the pulled src tag is a picture like so:
if(preg_match('/([jpg]{3}$)|([gif]{3}$)|([jpeg]{3}$)|([bmp]{3}$)|([png]{3}$)/', $src) == 1) {
//its an image
}
//我想依葫芦画瓢应该能弄出来吧~
</code>
$str = '<img border="0" src=\'/images/image.jpg\' alt="Image" width="100" height="100"/>';
preg_match('/(src=["\'](.*?)["\'])/', $str, $match); //find src="X" or src='X'
$split = preg_split('/["\']/', $match[0]); // split by quotes
$src = $split[1]; // X between quotes
echo $src;

//its an image
}
//我想依葫芦画瓢应该能弄出来吧~

还有一段代码，但是大概意思能看懂，抽空再尝试一下效果怎么样~
<code>
$htmlContent = file_get_contents('pageURL');
// read all image tags into an array
preg_match_all('/<img[^>]+>/i',$htmlContent, $imgTags);
for ($i = 0; $i < count($imgTags[0]); $i++) {
// get the source string
preg_match('/src="([^"]+)/i',$imgTags[0][$i], $imgage);
// remove opening 'src=' tag, can`t get the regex right
$origImageSrc[] = str_ireplace( 'src="', '', $imgage[0]);
}
// will output all your img src's within the html string
print_r($origImageSrc);
</code>
$htmlContent = file_get_contents('pageURL');
// read all image tags into an array
preg_match_all('/<img[^>]+>/i',$htmlContent, $imgTags);
for ($i = 0; $i < count($imgTags[0]); $i++) {
// get the source string
preg_match('/src="([^"]+)/i',$imgTags[0][$i], $imgage);
// remove opening 'src=' tag, can`t get the regex right
$origImageSrc[] = str_ireplace( 'src="', '', $imgage[0]);
}
// will output all your img src's within the html string
print_r($origImageSrc);
</code>
百度上搜索页好到了一段代码，还是没有尝试一下~
<code>
<?php
$str='<img decoding="async" border="0" src="1.jpg" alt=""/><img decoding="async" border="0" src="a.jpg" alt=""/><img decoding="async" src="test.jpg" />';
$pattern="/<[img|IMG].*?src=[\'|\"](.*?(?:[\.gif|\.jpg]))[\'|\"].*?[\/]?>/";
preg_match_all($pattern,$str,$match);
//print_r($match[1]);
print_r($match);
preg_match('/<img.+src=\"?(.+\.(jpg|gif|bmp|bnp|png))\"?.+>/i', stripcslashes($_POST['content']), $match);
$litpic = $match[1];
?>
</code>
