How to solve the garbled js text in php

In the web development process, PHP is a widely used server-side scripting language, while JavaScript is a commonly used client-side scripting language. It is a very common process to process data in PHP and then display the data in a web page through JavaScript. However, in some cases, when using JavaScript to display PHP data, you may encounter text garbled problems.

This problem may be caused by one of the following reasons:

1. Encoding mismatch: The encoding formats of the server and client do not match.
2. Non-UTF-8 encoding: The string encoding is not UTF-8.
3. Sending HTTP header: The HTTP header is not set correctly.

So, how to solve this problem? Here are some possible solutions.

1. Ensure encoding consistency:

To solve this problem, you first need to ensure that the encoding on the server side and the client side are consistent. Generally speaking, UTF-8 is the most common encoding format and is a universal character set. Therefore, it is recommended to use UTF-8 as the encoding format.

In PHP code, set the encoding in the following way:

header('Content-type: text/html; charset=UTF-8');

In JavaScript code, you can set the encoding in the following way:

<meta charset="UTF-8">

Make sure the page is using the same encoding , which can effectively avoid the problem of garbled text.

2. Convert non-UTF-8 encoding:

If the string encoding is not UTF-8, you can use PHP's built-in mb_convert_encoding() function to convert to ensure its encoding is UTF-8.

$utf8String = mb_convert_encoding($string, 'UTF-8', 'OldEncoding');

Among them, $string is the input string, and 'OldEncoding' is the original encoding format.

This will convert the input string from the old encoding format to UTF-8 encoding.

3. Send HTTP headers:

Ensuring that the HTTP headers are set correctly is also an important step to avoid garbled text problems. In an HTTP request, the Content-Type header contains character set information, which tells the browser how to parse the document.

Therefore, the correct HTTP header must be sent in the PHP code:

header('Content-type: text/html; charset=UTF-8');

You can also use the curl library to set the HTTP header, for example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: text/html; charset=UTF-8'));
$result = curl_exec($ch);
curl_close($ch);

Summary

The text garbled problem may reduce the user experience of the website. In order to avoid this problem, you need to ensure that the encoding on the server and client is consistent and convert the string encoding to UTF-8. Also, sending the correct HTTP headers in your PHP code is an important step. Through these measures, the problem of garbled JS text in PHP can be effectively solved.
