PHP: Sorting Arrays of Arrays. PHP provides a range of functions for sorting data based on either the key or value of an associative array. Where it gets complicated is when you need to sort an array of associative arrays by one or more conditions. This is a very common task for PHP programmers as data returned from database/SQL queries often appears in associative array format (i.e. using pg_fetch_assoc and mysql_fetch_assoc).
Epididymitis is an inflammation of the epididymis. The epididymis is the tube through which sperm pass. The tube is located at the back of each testicle. Epididymitis can affect both testicles, but it most often occurs on just one side.
Epididymitis - In adult men, one of the most common causes of sore testicles outside of trauma is a condition called epididymitis, an infection of the testicle. The epididymis is an organ at the upper rear of the testicle whose function is to store sperm. Besides being attached to the testicle itself, the epididymis is also connected to the wall of the scrotum, the sack-like tissue containing the testicles, and as such serves to keep the testicles from being twisted.
