In 5.0.4, phpversion() seeminly cannot be manipulated by trim(), despite returning a string.
If you *do* want to compare PHP versions numerically, then here's the easiest/quickest way I
could think of to make an integer value out of the returned phpversion() string value:
<?php
$phpVersion=explode(".",phpversion());
$phpVersion=substr($phpVersion[0],0,1);
$phpVersion.=substr($phpVersion[1],0,1);
$phpVersion.=substr($phpVersion[2],0,1);
if ($phpVersion>="420") {
//... Do stuff here ...
}
?>
(My real example would have had all three substr() calls on one line, but it makes the string too
long for the PHP comment thing)
The above removes the need for any regexp calls, which I feel is neater.
