Compiler settings

We use php 8.1.2-1ubuntu2 to compile your program with the following command:

$ php -n -d display_errors=stderr -d html_errors=0 -l {files}

• {files} is a space-separated list of all files.

Runtime settings

$ php -n -d display_errors=stderr -d html_errors=0 -d memory_limit={memlim}m -r "{php_preamble} require {mainfile};"

• {mainfile} is the entrypoint file (you can specify which file this is when submitting).
• {memlim} is the actual memory limit for the problem you are submitting to.
• {php_preamble} sets a custom error handler that treats warnings as errors.
