PHP - 从字符串中删除<img>标记

Question

嘿,我需要从字符串中删除所有图像,但我找不到正确的方法.

这是我尝试过的,但它不起作用:

preg_replace("/<img[^>]+\>/i", "(image) ", $content);
echo $content;

有任何想法吗？

Answer 1

试着放在\前面>.

编辑:我刚测试你的正则表达式,它工作正常.这是我用过的:

<?
    $content = "this is something with an <img src=\"test.png\"/> in it.";
    $content = preg_replace("/<img[^>]+\>/i", "(image) ", $content); 
    echo $content;
?>

结果是:

this is something with an (image)  in it.

Answer 2

您需要将结果分配回来,$content因为preg_replace不会修改原始字符串.

$content = preg_replace("/<img[^>]+\>/i", "(image) ", $content);

Answer 3

我建议使用这种strip_tags方法.

Answer 4

肖恩它工作正常我刚刚使用此代码

$content = preg_replace("/<img[^>]+\>/i", " ", $content); 
echo $content;

//结果它只是纯文本.有用!!!
