We had a requirement, where we were asked to format the content from a big database table. And the format includes making sentences to sentence case, format simple numbers to comma separated numbers within those sentences and remove the extra spaces. Here is the solution. Hope this helps you. function formatString($string){ //number formatting $string1 = preg_replace_callback('/\d+/', function($match){return number_format($match[0]);}, $string); //removing extra spaces $string2 = preg_replace('/\s+/', ' ', $string1); //sentence case $sentences = preg_split('/([.?!]+)/', $string2, -1, PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE); $new_string = ''; foreach ($sentences as $key => $sentence) { $new_string .= ($key & 1) == 0? ucfirst(strtolower(trim($sentence))) : $sentence.' '; } return trim($new_string); } $str = "it was an awesome day. i bought shares f...

It will irritate the user to scroll to the bottom of page to read. So, the pagination. Divide the list of items in number of pages and navigate to each by clicking on each page number displayed. At the beginning, the pagination was simple was limited to 10-15 pages, but after some time in real time the requirement has grown to 10 multiple pages. Solution was to show first few page numbers, last few page numbers and in middle show the ellipsis(...). As you navigate to any page it would show definite page numbers to both the sides. /** * Pagination file * * This file provides the google like pagination solution * * @category Saral * @packag...
