This article will explain in detail how to read the fopen address with Chinese URL in PHP. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

But there was a problem reading a picture yesterday, and it was later found that there were Chinese characters in the URL.

For example, this is the case:

The copy code is as follows:

$files = fopen ('http://www.website.com/ my PP.jpg',' rb')

The return value of "$files" will be "False". The first thing I think of is to encode URL with urlencode, but it still doesn't work. Urlencode will also encode the ":" and "/" characters, so URL is not URL. Oh, it's a bit of a twist, so replacing the coding of the ":" and "/" characters should be fine.

The copy code is as follows:

$url = 'http://www.website.com/ my PP.jpg'

$url = preg_replace ('/\% 3A fopen,':', preg_replace ('/\% 2F _ url,'/', urlencode (urldecode ($url); $file = fopen ($url, 'rb')

Try it. Hey, it's all right. Let's review the fopen () function again:

The fopen () function opens a file or URL. If the opening fails, this function returns FALSE. If it is successfully opened, this function returns TRUE.

First, grammar:

The copy code is as follows:

Fopen (filename, mode, include_path, context)

Parameter describes the file or URL that filename specifies to open. Mode specifies the type of access required to the file / stream. The possible values are shown in the table below. If include_path also needs to retrieve files in include_path, you can set this parameter to 1 or TRUE. Context specifies the environment of the file handle. Context is a set of options that can modify the behavior of a flow.

2. Possible values of mode parameter:

Mode says "r" read-only to open the file pointer to the file header. "r +" read-write mode to open the file pointer to the file header. "w" write mode to open, point the file pointer to the file header and cut the file size to zero. If the file does not exist, try to create it. "w +" read and write to open, point the file pointer to the file header and cut the file size to zero. If the file does not exist, try to create it. "a" open in write mode, pointing the file pointer to the end of the file. If the file does not exist, try to create it. "a +" opens in read-write mode and points the file pointer to the end of the file. If the file does not exist, try to create it. "x" creates and opens as a write, pointing the file pointer to the file header. If the file already exists, the fopen () call fails and returns FALSE with an error message at the E_WARNING level. If the file does not exist, try to create it.

This is equivalent to assigning the O_EXCL | O_CREAT tag to the underlying open (2) system call.

This option is supported by PHP 4.3.2 and later and can only be used for local files. "x +" is created and opened in read-write mode, pointing the file pointer to the file header. If the file already exists, the fopen () call fails and returns FALSE with an error message at the E_WARNING level. If the file does not exist, try to create it.

This is equivalent to assigning the O_EXCL | O_CREAT tag to the underlying open (2) system call.

This option is supported by PHP 4.3.2 and later, and can only be used for local files. This is the end of the article on "how to read fopen with Chinese URL address in PHP".
