http://www.phpro.org/feed.php PHP Articles from PHPRO Fri, 25 Apr 2008 12:58:31 +0000 eZ Components Feed dev (http://ezcomponents.org/docs/tutorials/Feed) http://www.rssboard.org/rss-specification http://www.phpro.org/articles/Google-App-Engine.html Google has recently opened up their API for a selective ten thousand developers with many tens of thousands more lined up to get access to what is the hotest access in town. But many are not so sure that the Google offering is all it seems to be, and comparisons to a wolf in sheeps clothing abound with concerns that this may be just another bid by Google to access cheap applications without the added cost of in house development. http://www.phpro.org/articles/SUN-MySQL-PgSQL.html It is no secret that SUN have recently purchased the MySQL database and have plans which include closing source on code they develop for it. This is well within their rights, however, should the open source community continue to support MySQL in its new Enterprise incarnation? http://www.phpro.org/articles/Google-Summer-Of-Code-2008.html Google have released the final assignments for the 2008 Google Summer Of Code. 2008 features some heavy weight additions to teh GSoC and is sure to put in a good performance. http://www.phpro.org/articles/Pro-PHP-Book-Review.html First time author Kevin McArthur has launched his first book directly at advanced PHP users. In the face of many other PHP books circulating now, what does this new venture have that others do not? Named Pro PHP it is not immodest and promises much but what does it deliver? See what the all the hype is about. http://www.phpro.org/examples/Create-Columns-From-Array.html Creating columns from an array or from a database result set can seem a little tricky. The key to making it happen is the PHP modulo operator. With some simple math, database result sets and arrays can be rendered in two, three, four or more columns. http://www.phpro.org/examples/Convert-Seconds-To-Words.html This function takes a UNIX TIMESTAMP as generated by strtotime or from any source and converts it into a human readable notation. Convert seconds to words is a function that should be done at the application level and not from from SQL queries as this may interfere with display logic. http://www.phpro.org/tutorials/Asynchronous-Form-Submission-With-Xajax.html This short tutorial describes and shows how to submit a form asynchronoussly using xajax. This allows users to submit a form without a page reload. Ideal for login scripts etc. The tutorial follows on to show how the response form the form can be manipulated by adding effects from the scriptaculous library. The first of these is adding a fade effect to the form response. http://www.phpro.org/examples/Create-Test-Database.html Here is a small but useful script to create test data for databases. Two test tables are created with PDO and filled with various data types including Binary (BLOB) data. http://www.phpro.org/articles/eZ-Components-Alpha-Release.html The eZ Components team has release a new alpha package which includes many new additions to the already feature rich component library. Along with bug fixes and optimizations eZ is set to maintain its lead in web componentry for web applications. http://www.phpro.org/articles/Fixing-The-Internet.html In a recent article, internet developer Noel Forbes outlines what the problems with internet is and how a new path forward may be found within already existing technologies. Not content with simply whining about incosistencies with various among Internet developers, Forbes shows a model for a new Internet. Could we be seeing the first murmurings of Web 3.0. http://www.phpro.org/articles/Microsoft-Purchase-Yahoo-For-62-Billion.html The heat in the internet advertising just got turned up to eleven as Microsoft finally put pay to the resistance of Yahoo and settled on a price reported to be 62 Billion Dollars (USD). This is not a merger, this is a hostile take over, but what to the pundits think? Will Google respond with predatory pricing? 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/tutorials/Geo-Targetting-With-PHP-And-MySQL.html Geo targetting and Geo location are big money now in web applications. Companies such as Yahoo and Google offer maps and the ability to put markers on maps with locations of stores or cities within a given radius of a zip code. This tutorial shows how to calculate the latitude and longitude of a zip/post code or the latitude and longitude of stores within a 10 mile radius. These latitude and longitude calculations can then be used to create maps in other applications. The hard number crunching is handled in the database to improve speed as the some of the calculations are complex. http://www.phpro.org/tutorials/Dropdown-Select-With-PHP-and-MySQL.html Creating drop down lists for HTML forms can be done in several ways. Options for the drop downs may fetch the values from an array of from database results. This tutorial uses both methods to create a drop down select and adds a function for the creation of a multiple select also. http://www.phpro.org/articles/eZ-Components-Cache.html The team at eZ Components are once again pushing PHP technology to the limit. The functionality and flexibility of the eZ Cache component is set to be extended to increase performance at several different levels. 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/tutorials/Design-Patterns.html Many people are familiar with a few design patterns used with PHP. MVC and singleton patterns proliferate applicatios to create a coding frameworks for PHP applications. This tutorial introduces some of the most common design patterns used in PHP, and some lesser known patterns that can help produce enterprise level applications.
