Eu tenho este código para processar um arquivo de configuração:

<?php
$config = '[log]
log_writers[] = "file"
log_writers[] = "screen"

[General]
maintenance_mode = 0
enable_browser_archiving_triggering = 0
enable_sql_optimize_queries = 0
force_ssl = 1';

echo preg_match_all( '/^maintenance_mode[ \t]*=[ \t]*\d$/m', $config );

O eco exibe0

Atualizando o regex para:

echo preg_match_all( '/^maintenance_mode[ \t]*=[ \t]*\d\s$/m', $config );

resultados no esperado1

POR QUE??

Eu até verifiquei minha sanidade no regex101
