How to use PHP to jump without garbled characters

When writing a website in PHP, you may encounter garbled characters when jumping, which may affect the user experience of the website. This article will introduce how to use PHP to make jumps without garbled characters.

1. Set encoding

Add the following code at the beginning of the PHP file and set the encoding format to UTF-8.

header("Content-Type:text/html;charset=utf-8");

This can ensure that the output content is output in UTF-8 encoding format to avoid garbled characters.

2. Specify web page encoding

Add the following code in the header of the HTML page to specify the web page encoding as UTF-8.

<meta charset="utf-8">

Doing this can ensure that the browser displays the web page content correctly and avoids garbled characters.

3. Use header function to jump

When using header function to jump, you need to pay attention to some details.

First of all, all html codes need to be output before the header function. Because the header function needs to be executed before outputting the content.

Secondly, the jump link needs to be URL encoded. Just use the urlencode function.

Finally, you need to add the exit function to ensure that there is no other output from the page.

The following is an example code:

';
echo '';
echo '';
echo '<meta charset="utf-8">';
echo '';
echo '
';
echo '';

$url = 'http://www.example.com/?name=张三&age=18';
$url = urlencode($url);
header("Location: $url");

echo '';
echo '';
exit();
?>

The address of the jump page contains Chinese characters. After encoding, the jump can be successful and no garbled characters will appear.

4. Use meta tag to jump

In addition to using the header function to jump, you can also use meta tags to jump.

<meta http-equiv="refresh" content="0;url=http://www.example.com">

Among them, 0 in the content attribute value indicates an immediate jump, and the url attribute specifies the target address of the jump.

It should be noted that using the meta tag to jump will display a countdown on the page, which may not be a good user experience.
