php-5.2

So I've got a script that needs to run on several sites. I've got one version of the script that is optimised with some new PHP 5.3 functions, however some sites are 5.2 etc. This code: if (version_compare(PHP_VERSION, '5.3.0') >= 0) { Do the optimised 5.3 code (Although 5.2 throws syntax errors for it) } else { do the slower version of code } However, on the 5.2 servers, it will detect the "syntax errors" in the first if condition, even though it technically should skip that content, I'm aware that PHP still scans the whole file. How can I get 5.2 to ignore the first if completely (I know I

I know it's possible to do the following with PHP 5.3 (anonymous functions), but is there a similar alternative in older PHP version (pre-5.3)? $exampleArray = array( 'func' => function() { echo 'this is an example'; } Is it possible to do this with __call or typecasting the function as an (object) first? Also, I tried making the function un-anonymous by giving it a name, but this didn't seem to work. If you want to create anonymous in PHP < 5.3, you can use create_function function. Also Here is interesting information about callbacks (may be usefull). Example using create_function # This

I have a string value that I'm trying to extract list items for. I'd like to extract the text and any subnodes, however, DOMDocument is converting the entities to the character, instead of leaving in the original state. I've tried setting DOMDocument::resolveExternals and DOMDocument::substituteEntities for false, but this has no effect. It should be noted I'm running on Win7 with PHP 5.2.17. Example code is: $example = '<ul><li>text</li>'. '<li>½ of this is <strong>strong</strong></li></ul>'; echo 'To be converted:'.PHP_EOL.$example.PHP_EOL; $doc = new DOMDocument(); $doc->resolveExternals =

I am using PHP 5.2. If I new an object at one page, when will this object be destructed? Is the object destructed automatic at the time that user go to another .php page or I need to call __destructor explicitly? It will be destructed (unloaded from memory) at the end of the page load, or if you unset all references to it earlier. You will not have to destroy it manually since PHP always cleans up all memory at the end of the script. In fact, you should never call __destruct yourself. Use unset to unset the reference to an object when you want to destroy it. __destruct will in fact not destroy

for some reasons, our hosting company used PHP 5.2 and doesn't even have mysqli and PDO pre-installed. I have no choice but to rewrite some part of my code to make it 5.2 compatible. so, here is my question: In PHP 5.2 Anonymous function is not supported, so i did the following test to make sure I'm changing the code correctly: class foo{ public function toString(){ $arr = array("a", "b"); $arr2 = array("c", "d"); print_r(array_map('mapKeyValue', $arr, $arr2)); } private function mapKeyValue($v, $k){ return $k."='".$v."'"; } } $foo = new foo(); echo $foo->toString(); but the above would give
