Determining File Size of 2GB Files Without External Programs in PHP
PHP's limitations in handling file sizes over 2GB can be frustrating. However, there are methods to overcome this without resorting to external programs.
One approach is through "Big File Tools," an open-source project that manipulates files exceeding 2GB in PHP, even on 32-bit systems.
Another technique involves a three-pronged approach:
- Platform-Appropriate Shell Command: Attempting to utilize platform-specific command line tools, such as shell substitution modifiers on Windows or the "stat" command on *nix/Mac systems.
- COM Interface on Windows: Exploring COM, the Component Object Model, to retrieve file size information.
- Fallback to filesize(): As a last resort, reverting to PHP's native "filesize()" function, which may be limited depending on platform and file size.
