Hi... I used your script and my results are different from yours. The post-while increment is generally the fastest result on my machine (Core 2 Duo, php 5.2.1 and apache 2.2.4). I ran the script multiple times: [schnipp ] For pre-increment (100000): 0.066 For post-increment (100000): 0.066 While pre-increment (100000): 0.028 While post-increment (100001): 0.025 [schnipp ] Greetings Mario -- ----------------------------------------------------- | havelsoft.com - Ihr Service Partner für Open Source | | Tel: 033876-21 966 | | Notruf: 0173-277 33 60 | | http://www.havelsoft.com | | | | Inhaber: Mario Günterberg | | Mützlitzer Strasse 19 | | 14715 Märkisch Luch | -----------------------------------------------------
