subsequent calls to create_function create raising names lambda_$n *lasting over scripts end*

I´ve played around with create_function and I´ve noticed that subsequent calls create names with lambda_[number of call] even if they´re subsequent by pressing "reload" in the browser. After a timeout of about 10 to 15 seconds it starts again with 1, what does this mean, can I make use of it? Eg. can I reuse the function I´ve created on loading the page the first time and then a second later in the same script without using create_function... If so, I don´t know how? I didn´t get that... regards -- o----------0-¬---------O-·---¬----o---®-----o o O ° . | http://www.kiffen.de | pRoteçt y0ur bRaín |0 O ° ¤ ° · 0°·³°²'²³-¹'³´³°^°³~³²³°'³²²¨³²^³¹³²°²³`³º³°Þ ° o © ° . · | psychedelic experience | gott@kiffen.de | O ° o ° o-¬--o--0-----©-·--O-----o-----0-¤----------o 0 ° · ° . ¤ ·
