Question

Below are two methods commonly used in most php codes for fetch mysql data .

1. mysql_fetch_array()
2. mysql_fetch_assoc()
<

Answer 1

The benchark shown in your example uses mysql_fetch_array() without any argument to specify MYSQL_ASSOC or MYSQL_NUM, so it defaults to MYSQL_BOTH... this will rather skew the result as it has to load twice as many array elements as mysql_fetch_assoc(). So I'd suggest it isn't a valid benchmark.

In reality, there should be very little to differentiate between mysql_fetch_array() with MYSQL_ASSOC and mysql_fetch_assoc(), and it cerayinly won't be the biggest overhead in your script.
