如何从上述两个字符串中获得所需的输出?我试过下面的方法,但效果似乎不太好
$item_content = str_replace('> ', '> <p>', $item_content);
$item_content = str_replace('>', '> <p>', $item_content);
$item\u content=str\u replace(“>”、“>”、$item\u content);
$item_content=str_replace(“>”、“>”、$item_content);
感谢您的帮助。使用
DOMDocument
:
$str = '<img ... /> text ...';
$html = new DOMDocument();
$html->loadHtml($str);
$img_tag = $html->getElementsByTagName('img')->item(0)->C14N();
$text = trim($html->textContent);
$str='text…';
$html=新的DOMDocument();
$html->loadHtml($str);
$img_tag=$html->getElementsByTagName('img')->item(0)->C14N();
$text=trim($html->textContent);
然后,您可以任意方式输出:
echo "{$img_tag}\n<p>{$text}</p>";
echo“{$img_tag}\n{$text}”;
您可以使用正则表达式。它将是:
$str = '<img src="http://www.blogcdn.com/www.engadget.com/media/2013/10/ipad-air-hands-on-angle.jpg"> Apple\'s plan to launch the iPad Air with cellular data support for T-Mobile was apparently just the start of a larger strategy.

if(preg_match('/^(<img[\S\s]+?>)([\S\s]*)$/i', $str, $matches)) {
$img = $matches[1];
$text = trim($matches[2]);
echo "$img\n<p>$text</p>";
}

if(preg_match('/^()([\S\S]*)$/i',$str,$matches)){
$img=$matches[1];
$text=trim($matches[2]);
回显“$img\n$text”;
}
@Beardy检查$html->getElementsByTagName('img')->项(0)
是否返回NULL
。有了这些,你就可以解决这个问题了。
