Answer 1

不太会写正则$str="company_id=4|country_id=1|categoryname=0|typename=0|game_tag=2,12,7,|test_f_start=2010-7-5|test_f_end=2010-7-20|test_n_start=2010-7-19|test_n_end=2010-7-19|test_g_start=2010-7-19|test_g_end=2010-7-5";preg_match('/game_tag=(\d+,\d+,\d+)/',$str,$game_tag);print_R($game_tag[1]);

Answer 2

preg_match('/game_tag=([0-9]+,)*\|/',$str,$game_tag);

Answer 3

game_tag=2,12,7, 这个不规则！假如是game_tag=1，25，3，54，25呢 

Answer 4

$str="company_id=4|country_id=1|categoryname=0|typename=0|game_tag=2,12,7,|test_f_start=2010-7-5|test_f_end=2010-7-20|test_n_start=2010-7-19|test_n_end=2010-7-19|test_g_start=2010-7-19|test_g_end=2010-7-5";preg_match('/game_tag=((\d+,){3})/',$str,$game_tag);print_R($game_tag[1]);
