PHP regexp：替换文本字符串中的一段 URL

请帮助理解 php 正则表达式。有这个字符串：

<a href="/kop/product/acer-timeline-5810tg-944g50mi" class="imagecache imagecache-product_list imagecache-linked imagecache-product_list_linked"><img src="http://localhost/kop/sites/default/files/imagecache/product_list/Acer-Timeline-1.jpg" alt="Acer As Timeline 5810TG-944G50Mi" title="Acer As Timeline 5810TG-944G50Mi" class="imagecache imagecache-product_list" width="100" height="100" /></a>

我需要替换中位于imagecache/和/SOME_TEXT之间的product_list标签，例如 product_list_replaced

如有任何帮助，

谢谢

如果您只是需要这样做，那么使用 str_replace()，您可以这样做：

$text = '<a href="/kop/product/acer-timeline-5810tg-944g50mi" class="imagecache imagecache-product_list imagecache-linked imagecache-product_list_linked"><img src="http://localhost/kop/sites/default/files/imagecache/product_list/Acer-Timeline-1.jpg" alt="Acer As Timeline 5810TG-944G50Mi" title="Acer As Timeline 5810TG-944G50Mi" class="imagecache imagecache-product_list" width="100" height="100" /></a>';

$new = '<img>product_list_replaced</img>';
$match = 'imagecache/';

$newstr= str_replace($match, $replace, $text);

如果您对正则表达式感兴趣，请查看此站点< /a>

哈！

If you just need to do that is easier to use str_replace(), you can do it this way:

$text = '<a href="/kop/product/acer-timeline-5810tg-944g50mi" class="imagecache imagecache-product_list imagecache-linked imagecache-product_list_linked"><img src="http://localhost/kop/sites/default/files/imagecache/product_list/Acer-Timeline-1.jpg" alt="Acer As Timeline 5810TG-944G50Mi" title="Acer As Timeline 5810TG-944G50Mi" class="imagecache imagecache-product_list" width="100" height="100" /></a>';

$new = '<img>product_list_replaced</img>';
$match = 'imagecache/';

$newstr= str_replace($match, $replace, $text);
