PHP: Get language codes

Posted on 2010-08-31

My code does what I need it to however it seems awkward to be using explode twice to get the language codes from my string.

Is there a better performing way to do this?
<?php

$LanguageHader = 'en-us,en;q=0.9,af;q=0.8,zu;q=0.7,ru;q=0.6,fr-ch;q=0.5,de-at;q=0.4,es-ec;q=0.3,sv;q=0.2,cy;q=0.1';
$langs=explode(',',$LanguageHader);
foreach ($langs as $lang){
 $l=explode(';',$lang);
 echo $l[0] . '<br />';
}

?>

No, it is not worth optimizing.  Make sure your data bases are indexed correctly.  I/O operations are several orders of magnitude slower than in-memory instructions.

<?php

$LanguageHader = 'en;q=0.9,af;q=0.8,zu;q=0.7,ru;q=0.6,fr-ch;q=0.5,de-at;q=0.4,es-ec;q=0.3,sv;q=0.2,cy;q=0.1';


$LanguageHader = 'en;q=0.9,af;q=0.8,zu;q=0.7,ru;q=0.6,fr-ch;q=0.5,de-at;q=0.4,es-ec;q=0.3,sv;q=0.2,cy;q=0.1';

$pattern="/[a-z]{2}\;[a-z]\=[0-9.]{3}/i";
preg_match_all($pattern,$LanguageHader,$cont);
echo "<pre>";
print_r($cont);
echo "</pre>";

}


Hope this helps

If the only language code you want is the first one, some kind of strpos() and substr() might work.  But whatever solution you're trying to optimize probably already completes in 0.00001 second or less.  So the optimization process is a little like milking a mouse - a lot of work for very little result!
