Determine php major from php version

Question

I have an array $cfg=Array('5.3', '5.4') which contains major Php versions. I want to determine major from version. For example if input is 5.4.10-1ubuntu3 the response should be 5.4. My code is this:

 foreach ($cfg as $key => $phpMajor) {
    if (version_compare($phpVersion, $phpMajor, '>=') and version_compare($phpVersion, $cfg[$key+1], '<')) {
        var_dump($phpMajor);
    }

}

But this is not cover my all possibilities. Can you help me please?

Where do you get that version string from? Maybe you're just looking for the PHP_VERSION, PHP_MAJOR_VERSION, PHP_MINOR_VERSION constants? — deceze

<?php
$subject = '5.4.10-1ubuntu3'; 
$matches = array();
$pattern = '#[0-9]{1,1}.[0-9]{1,2}#';
if (preg_match ($pattern , $subject, $matches) == 1) {
    print "Major version : " . $matches[0] ;
}else {
    print "Can not found version";
}
