高手帮忙看一段代码，为什么内存耗尽

<br />
$i = -1;<br />
while( $i++ < 495000000 ) {<br />
        $rand_uid = rand(100000000,105000000);<br />
        $rand_fuid = rand(100000000,999999999);<br />
        $tab_name = get_hash_table('friends',$rand_uid);<br />
        $up_array = array(<br />
                                'uid' => $rand_uid,<br />
                                'fuid' => $rand_fuid<br />
                );<br />
        insert_table($tab_name, $up_array,1);<br />
}<br />


需要测试数据，要把5亿条数据写入到500个mysql表里面，直接用php命令执行的代码，为什么会内存耗尽？

多谢！
