Two test tables are created with PDO and filled with various data types including Binary (BLOB) data. http://www.phpro.org/examples/80000-Word-List.html Some times you just need a list of words, a big list. Here is a list of about eighty thousand words to help with.. well whatever! http://www.phpro.org/examples/Radians-To-Degrees.html This function complements the Degrees to Radians functions by doing exactly the opposite, converting radians to degrees. Handy for those geographical calculations need when plotting points on a map with with online applications such as google maps or yahoo maps. http://www.phpro.org/examples/Degrees-To-Radians.html Here is a handy function for those messing with goe location and geo targetting or other geo graphical toys. This function convert degrees to radians for use in map plotting etc. http://www.phpro.org/examples/Get-Riemann-Distance.html This function will calculate the distance between two points on the earth using the great circle distance formulae. This function should not be used to calculate linear distances, instead use the GetLinearDistance function. This function will return a value in miles, nautical miles or kilometers http://www.phpro.org/examples/Get-Linear-Distance.html This function calculates the linear distance between two points. Give to x1 y1 x2 and y2. This is not a function for calculating distances between latitudes and longitutes, for that purpose see the Get Riemann Distance function. http://www.phpro.org/examples/US-Cities-Zip-Codes.html Ever needed a comprehensive list of US cities, zip codes, latitude and longitude? Well you can pay up to $100 dollars for one or you can use this database of over forty one thousand (41000) cities and their locations.

By default these gradients are vertical. This example code provides a method of creating horizontal gradients using simple rotation. http://www.phpro.org/examples/Password-Strength-Tester.html PHP Security is an important part of creating forms. Recently there has been a proliferation of password strength testing scripts about, each with their own algorithms for checking the strength of passwords. This example shows how it is done. http://www.phpro.org/examples/Twenty-Four-Hour-to-Twelve-Hour.html Converting 24 hour time to 12 hour can be a hassle when you have different formats.
