The zip_entry_read() function is a built-in function in PHP that is used to read the contents of a file in a zip archive. The function requires an open file handle, which can be obtained using zip_entry_open().
The syntax of the zip_entry_read() function is as follows:
string zip_entry_read(resource $zip_entry, int $length)
$zip_entry is the file handle returned by zip_entry_open() and
$length is the number of bytes to read.
Let's take a look at a practical example of using zip_entry_read() in PHP.
Example: Reading the Contents of a File in a Zip Archive
Suppose you have opened a zip archive using the PHP zip functions and want to read the contents of a file in the archive. You can use the zip_entry_read() function to do this, like this:
$zip = zip_open("example.zip"); $zip_entry = zip_read($zip); // open the file $zip_entry_handle = zip_entry_open($zip, $zip_entry, "r"); // read the contents of the file $file_contents = zip_entry_read($zip_entry_handle, zip_entry_filesize($zip_entry)); // close the file handle zip_entry_close($zip_entry_handle); echo "The contents of the file are: " . $file_contents;
This code opens a zip archive file "example.zip" using zip_open(). We then read a file in the archive using zip_read() and open the file using zip_entry_open() with mode "r". The contents of the file are read using zip_entry_read() and the handle is closed using zip_entry_close(). Finally, the contents of the file are outputted to the user.
In this article, we've discussed the PHP zip_entry_read() function and how it can be used to read the contents of a file in a zip archive. We've explained what the function does, its syntax, and provided an example of how it can be used in a practical scenario. By using zip_entry_read() in your PHP applications, you can easily read the contents of files in a zip archive and use that information as needed.
