New from his blog Brendon has a list of what he thinks are ten PHP functions you'll never use.

When scripting in PHP, we often restrict ourselves to a limited number of API functions: the common ones, like print(), header(), define(), isset(), htmlspecialchars(), etc. [...] The PHP API actually offers a lot of functionality, some useless and some useful; often seldom used. I have been looking through the available functions and was interested to find some really cool functions that I should have known about.

Here's his list of functions, some of which are more on the "special needs" list than the "never use" list:

• sys_getloadavg
• pack
• cal_days_in_month
• _()
• get_browser
• debug_print_backtrace
• metaphone
• natsort
• levenshtein
• glob
