Reading file in as binary data

Copy linkTweet thisAlerts:
Nov 12.2004

I’m trying to use the [url=http://www.zend.com/codex.php?id=696&single=1]Zend ZIP class[/url] and at some point I have to read my file into a binary data string and then store it into the Zip file. This may be a very simple process, but I don’t know how to do it. The documentation at Zend just says

[code]
//add the binary data stored in the string ‘filedata’
$filedata = “(read your file into $filedata)”;
$zipfile -> add_file($filedata, “dir/file.txt”);
[/code]

The files are of varying types : text, jpg, tif, xls, etc…

I’ve looked around various sites including this one, but I may be typing in the wrong search words. In anycase, can anyone give me a clue?

Thanks a mill,
– sharyn

@yunaNov 12.2004 — If you have a recent version of PHP (4.3.0 or later), use file_get_contents() as documented here:

http://us2.php.net/manual/en/function.file-get-contents.php

In earlier versions, you need to open the file with fopen(), then use fread() like this example from the manual page for fread():

[code=php]
// get contents of a file into a string
$filename = "/usr/local/something.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
[/code]

Both these functions are binary-safe.

Thanks for your help. It turns out file_get_contents() worked exactly the way I needed ?
