<?php
if (is_file("/tmp/very_large_file")) {
	echo "is file";
} else {
        echo "is not";
}
?>
~

if the file /tmp/very_large_file is larger than 2 GB, php reports the error:

Warning: stat failed for /tmp/very_large_file (errno=79 - Value too large for defined data type)


php_4.2.3 is compiled as an apache_1.3.27 module

What version of Solaris are you running?

Many unixes (even current ones) use a signed int (32-bit) for the st_size element of the stat struct used by their c-library's stat() function.

Try taking a look in stat.h and/or types.h if you'd like to confirm this on your local system.

Does the stat command (from the shell) return sensible output when run against this file?
 [2003-01-12 18:22 UTC] bonebakker at attbi dot com 
Current OS is Solaris 9u1, 64 bit kernel.
Checking types.h and stat.h indicates that Solaris uses an off_t type for the stat structure. off_t is either a long,  or a longlong_t, defined as long long.

It seems to me that the stat structure in Solaris has the correct type. This is also indicated by the fact that I can use the stat(2) functions to stat the file in a simple C-program without any errors (and get the correct file size), 
Solaris does not have a shell stat command (AFAIK).

PHP does not support 64-bit stat'ing.
Additionally, PHP only supports signed 32-bit integers (unless your CPU is 64-bit native).
PHP could return large file sizes as floating point numbers, but the infrastructure for 64 bit stat is not in place at this time.

I'm changing this to a feature request, as this is the "expected" behaviour.

Problem tracked in #27792.
