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.
Each epididymis is directly attached to the testicle so that if the epididymis becomes infected or develops inflammation, the testicle may also develop infection or inflammation. This is termed epididymo-orchitis (infection/inflammation of both the epididymis and testicle). Also, testicular infection is the most common reason for inflammation in the scrotum. The other end of the epididymis attaches to the vas deferens which leads to the prostate gland and then to the urethra.
