測試PHP中Mysql的使用記憶體

結果:
             100             1000                10000
---------------------------------------------------------------------
MYSQL_NUM:      187.4/187.5     1294.8/1294.9       12394.0/12394.1
MYSQL_ASSOC:    188.2/188.2     1302.7/1302.7       12472.2/12472.2
MYSQL_BOTH:     250.6/250.6     1927.6/1927.6       18722.1/18722.2
MYSQL_OBJ:      191.0/191.1     1326.6/1326.6       13067.5/13067.5

*數字: memory_get_usage/memory_get_peak_usage (kb)

結論:
mysql_fetch_object與mysql_fetch_array所佔用的記憶體差不多.
