What compiler flags are necessary for PHP to support large files on Linux systems?

When working with large files in PHP on Linux systems, it is important to ensure that the compiler flags are set correctly to support these large files. To do this, you need to include the `-D_FILE_OFFSET_BITS=64` flag when compiling PHP. This flag enables support for files larger than 2GB on 32-bit systems. ```bash ./configure CFLAGS="-D_FILE_OFFSET_BITS=64" && make && make install ```
