  - by Jigs

  What is the easiest way to duplicate an image variable in PHP. Normally you can simply do $varnew = $varold. But with a GD library variable if I did the above and then edited $varnew then $varold would be effected too. Obviously one way would be to reopen the file or to make a new image and copy it into it. Is there an easier way?

  - by Tristan

  Hello, I'm a little afraid of using Wordpress because of his connotation "all made", plus my website is 100% hand coded, actually, i use the phpBB but it's not what I want cause visitors have to go out of the website to go to the forum to see the news.

• Classes. Whats the point?

  - by Ben Shelock

  I'm fairly new to OOP in PHP, I've made a couple of basic scripts but nothing impressive. All I've really taken from it is that it would probably be easier just make a collection of functions and include them. The structure of classes seems to just confuse what was otherwise a simple process. And in collating everything into a class it doesn't really add any functionality. So I'm clearly missing something. Could someone explain what functionality is added by creating classes

• How does this script work for the ImageShack.us API?

  - by vette982

  I'm looking into using the ImageShack.us API for uploading images from my website. I found this tutorial for using it with the XML return http://elliottback.com/wp/using-the-imageshack-xml-api/, but I'm not sure about what to do with it. Where do I enter my API key for this script? Furthermore, he shows the use of two PHP files - should these be combined into one file? Any help with this would be appreciated (examples would be even better).

• Why do exceptions usually have the suffix 'Exception' in the class name?

  - by Pheter

  It seems to me that it is rendundant information as the usage of the class will make it apparent that it is an exception. Furthermore, in PHP, the class must extend the Exception class so it will be apparent that it is an exception when looking at the class on its own. Despite this, developers usually apply the suffix 'Exception'. Why is this?

• Can str_replace mangle a UTF-8 encoded string if it's only given valid UTF-8 encoded strings as argu

  - by Manos Dilaverakis

  PHP's str_replace() was intended only for ANSI strings and as such can mangle UTF-8 strings. However, given that it's binary-safe would it have a problem if it was only given valid UTF-8 strings as arguments? Edit: I'm not looking for a replacement function, I would just like to know if this hypothesis is correct.

• How to emulate PHPs preg_split in ruby to capture offsets and delimiters?

  - by dimus

  I wonder if there is a way to get offsets and delimiters while I am splitting a string in ruby analagous to PHP preg_split: preg_split("/( |&nbsp;|<|>|\t|\n|\r|;|\.)/i", $html_string, -1, PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_OFFSET_CAPTURE); I imagine I can achieve it by traversing string by characters or using something heavy as treetop, but I would like to use something more convenient.
