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)

Where $zip_entry is the file handle returned by zip_entry_open() and $length is the number of bytes to read.

Usage Examples

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("");
$zip_entry = zip_read($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

echo "The contents of the file are: " . $file_contents;

This code opens a zip archive file "" 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.
