find out PHP version

[Anon]

how can I get the version of PHP?

because some functions aren't available in PHP3 I would like to do something like this in my scripts:

if ($php_version > 4) {
php4function();
}
else
{
php3function();
}

any ideas?

try this:

<?php

phpinfo();

?>

You should get all Information you need :-)

i am sorry, i think i gt your question wrong.
Why do you want to do

if ($php_version > 4) {
php4function();
}
else
{
php3function();
}

You can once look for the PHP-Version installed (see my last post). And then you know which functions are availible for use.
This would save time ...

you could use the phpversion() function to get the version of the currently running php parser and check the first character of that string to geht 3 or 4.

Rather than asking for the current version of PHP to see whether a given function is implemented, and in the process writing code that could easily break as soon as PHP5 comes out :-), you should test for the exsitence of the functions directly:

if(function_exists('function_name'))
{ code that uses function_name();
}
else
{ fallback code
}
