Question

我有以下字符串

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAABVYAAAMACAIAAABAXKuVAAAAA3NCSVQICAjb4U/gAAAgAElEQVR4Xu....">

现在我想将“uploads / imag1.jpeg”替换为

"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAABVYAAAMACAIAAABAXKuVAAAAA3NCSVQICAjb4U/gAAAgAElEQVR4Xu...."

我试试这个

$doc = new DOMDocument();

$doc->loadHTML('"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAABVYAAAMACAIAAABAXKuVAAAAA3NCSVQICAjb4U/gAAAgAElEQVR4Xu...."');
$tags = $doc->getElementsByTagName('img');
foreach ($tags as $t)
{
$t->setAttribute('src','uploads/imag1.jpeg');
echo $doc->saveHTML();
}

但这不能正常运作。我有正确路径的路径

localhost:83/mysite/images/imag1.jpg

但是我的代码给了我错误的路径，

localhost:83/mysite/image/uploads/imag1.jpg

由于此问题，更换无效。

我该如何替换呢？

这是PHP的解决方案：

<?php 

   echo '<img src="data:image/png;base64,'. base64_encode(file_get_contents("uploads/imag1.jpeg")) .'"/>;

?>
