PHP’s ucfirst function is very usefull when you want to change words first letters to uppercase and other letters to lowercase. Currently on PHP does not have a multibyte (UTF-8) version of ucfirst function. So I decided write my own multibyte mb_ucfirst function. Perhaps the multibyte version of ucfirst function is added later on PHP, so that’s why is better add this function only if it does not already exist.

PHP MongoDB (Mongo Database) Driver Installation on Linux, UNIX, BSD and Mac OS X MongoDB PHP driver is very simple install on Linux, UNIX, BSD and Mac OS X. You need just PEAR (PHP Extension and Application Repository) with PECL repository. Normally PHP development (dev) package and PHP Pear package installation from package management system is enough to get PEAR working. Also go-pear.php script can be used. Check that the PEAR and PECL are working with the following commands:

PHP has large number of predefined constants. This HOWTO will present the seven most important, most practical and most useful PHP Magic Constants. FILE – The full path and filename of the file. DIR – The directory of the file. FUNCTION – The function name. CLASS – The class name. METHOD – The class method name. LINE – The current line number of the file. NAMESPACE – The name of the current namespace This is example PHP script with comments, which demonstrate howto use all previously mentioned PHP Magic Constants.

I was using simple function to calculate difference between two dates and timestamps until I noticed, it’s not working correctly in long intervals. It’s very easy to calculate difference between two timestamps in seconds, but it’s much more complicated print difference in human readable format. The Internet can be found in a wide range of ways to do this thing, but as a rule they use a fixed amount of seconds for the year and the month.

This is a quick method to check with using cURL that Nginx/Apache (or any other web server) compression with Nginx ngx_http_gzip_module (gzip), Nginx google/ngx_brotli (br), Apache mod_brotli (br), Apache mod_gzip (gzip) and Apache mod_deflate (deflate) is working. Only the remote server headers are needed. Check that the Nginx/Apache Compression is Working Get headers curl -s -I -H 'Accept-Encoding: br,gzip,deflate' https://www.if-not-true-then-false.com -s option silent, disable progress bar. -I option which will make just HEAD request to server and get headers.

PHP Command Line Interface (CLI) has not built-in coloring for script output, like example Perl language has (perldoc.perl.org/Term/ANSIColor.html). So I decided to make own class for adding colors on PHP CLI output. This class works only Bash shells. This class is easy to use. Just create new instance of class and call getColoredString function with string and foreground color and/or background color. PHP Class for Coloring PHP Command Line (CLI) Scripts Output <?

In many cases, it is really useful to know the exact time for how long a PHP script is running or how long will take PHP web page load. On the other hand it is also useful to know that how long a particular script operation or part of page load will take. Following PHP Timing class is very simple to use, only create class and start timing and stop timing.

I think every PHP coders have come accross Arrays and stdClass Objects (belongs to PHP Predefined Classes). Sometimes it’s very useful convert Objects to Arrays and Arrays to Objects. This is easy if arrays and objects are one-dimensional, but might be little tricky if using multidimensional arrays and objects. This post defines two ultra simple recursive function to convert multidimensional Objects to Arrays and multidimensional Arrays to Objects. Function to Convert stdClass Objects to Multidimensional Arrays <?

This is guide howto install nginx, PHP 5.3 and FastCGI webserver with MySQL and/or PostgreSQL and Memcache support on Fedora 12 and Fedora 13, CentOS 5.5, Red Hat (RHEL) 5.5/6. nginx (engine x) is a robust, small and high performance http server, reverse proxy server and also mail proxy server.

BitLy (bit.ly) is a service which allows users to shorten, expand, share and track URLs (links). bit.ly can be accessed through bit.ly website and a robust and open API. Example: Shorten http://www.if-not-true-then-false.com/ url -> http://bit.ly/8cZ1fb Expand http://bit.ly/8cZ1fb url -> http://www.if-not-true-then-false.com/ This post deals with bit.ly API usage with a simple PHP Class. This PHP class allows to shorten normal urls, expand bit.ly urls and expand bit.ly hashes. BitLy PHP Class <?

Simple PHP function that formats the bytes to the desired form. Possible unit options are: Byte (B) Kilobyte (KB) Megabyte (MB) Gigabyte (GB) Terabyte (TB) Petabyte (PB) Exabyte (EB) Zettabyte (ZB) Yottabyte (YB) PHP byteFormat function for formatting bytes Function takes three parameter: (bytes mandatory, unit optional, decimals optional) <?php function byteFormat($bytes, $unit = "", $decimals = 2) { $units = array('B' => 0, 'KB' => 1, 'MB' => 2, 'GB' => 3, 'TB' => 4, 'PB' => 5, 'EB' => 6, 'ZB' => 7, 'YB' => 8); $value = 0; if ($bytes > 0) { // Generate automatic prefix by bytes // If wrong prefix given if (!

This is very easy way loop through dates (from date to date) with PHP strtotime() function. This example only echo dates, but of course this model can be used more complicated situations. <?php // Set timezone date_default_timezone_set('UTC'); // Start date $date = '2009-12-06'; // End date $end_date = '2020-12-31'; while (strtotime($date) <= strtotime($end_date)) { echo "$date\n"; $date = date ("Y-m-d", strtotime("+1 day", strtotime($date))); } Note: All different PHP strtotime() function syntaxes can be used.

As Part 1 (Howto create PostgreSQL table partitioning) shows, making of PostgreSQL partitioning needs a lot of SQL commands. So this Part 2 explains how SQL commands for PostgreSQL partitioning can be made with a simple PHP script. This example script make SQL for child tables, indexes, trigger function and parent table trigger. This example script can make PostgreSQL table partitioning with using Date ranges. Script can be configured with following configuration section:

It makes sense to optimize the site’s cascading style sheets (CSS), as it pages load faster, and it reduce the amount of data transferred, and just combining css files could significantly reduce requests to server. So users benefit from faster page loads and webmaster of the sites benefits from the cheaper price of the transferred data. I have used CSSTidy on many projects. And CSSTidy is very good tool for packing CSS and it can even fix CSS errors.

Browser cache is very useful when users download the same CSS and JS files multiple times. Some browsers, however, use the old CSS and JS files from the cache, even though they have been updated. This may lead to unpleasant situations, when the pages are displayed to the user with the wrong styles or pages will work incorrectly. Fortunately, these unpleasant situations is easy to avoid and let the browsers cache files as long as they are changed.
