<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Code Modernization: Use `stream_get_contents()` in `POMO_FileReader::read_all()`.
`stream_get_contents()` is faster than `fread()`, because the PHP core can decide how to best read the remaining file; it could decide to issue just one `read()` call or `mmap()` the file first.
Per the PHP manual, `file_get_contents()` or `stream_get_contents()` is the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by the OS to enhance performance.
