How can PHP be used to pass an image from one form to another, such as converting a JPEG image to SVG format?

To pass an image from one form to another in PHP, such as converting a JPEG image to SVG format, you can use the `imagecreatefromjpeg()` function to create a GD image resource from the JPEG file. Then, you can use the `imagepng()` function to output the image in PNG format. Finally, you can use an SVG template with an `<image>` tag to embed the PNG image into an SVG file.

// Load the JPEG image
$jpegImage = imagecreatefromjpeg(&#039;input.jpg&#039;);

// Create a PNG image from the JPEG image
imagepng($jpegImage, &#039;output.png&#039;);

// Embed the PNG image into an SVG template
$svgTemplate = &#039;&lt;svg xmlns=&quot;http://www.w3.org/2000/svg&quot; width=&quot;100&quot; height=&quot;100&quot;&gt;&lt;image xlink:href=&quot;output.png&quot; width=&quot;100&quot; height=&quot;100&quot; /&gt;&lt;/svg&gt;&#039;;

// Output the SVG content
echo $svgTemplate;
