Nezinu cik šis ir pilnīgs, bet.. Pārbauda vai strings nav tukšs un nesatur tikai atstarpes

function navTukss($s) {
if(!empty($s)) {
	$s = trim($s);
	if(!empty($s)) {
		return true;
	}
	else {
		return false;

1. funkcija - iegūst faila paplašinājumu

2. funkcija - pārbauda, vai fails ir attēls (tikai pēc paplašinājuma, kā jau mēs zinām, mime tips arī nav 100% drošs avots :))

	//Iegūstam faila paplašinājumu
function getFileExtension($file_name){
	$info = pathinfo($file_name);
	return $info['extension'];
}

//Pārbaudam, vai fails ir attēls
function isImage($file_name){
	switch(getFileExtension($file_name)){
		case "jpg" : return true;
		case "jpeg" : return true;
		case "gif" : return true;
		case "png" : return true;
		case "bmp" : return true;
	}
	return false;
}

Tā kā twittera API ir dažādi ierobežojumi uz pieprasījumu skaitu, vērtīgāk ir JSON datus iekešot lokāli (uzlabosies arī pieprasījuma ātrums), un atjaunot tikai reizi 5 minūtēs (vai līdz pirmajam apmeklētājam).

<?
function updateTwitter(){
	$path = "js/twitter.json"; //Vieta, kur glabājas JSON dati
	$username = "username"; //Lietotājvārds
	$entry_count = 6; //Atgriežamo ierakstu skaits
	$update_interval = 300; // 5 minūtes

	$url = "http://twitter.com/statuses/user_timeline/$username.json?callback=twitterCallback2&count=$entry_count";
	$stat = stat($path);
	$last_mod = (int)$stat[9];
	$delta_mins = time() - $last_mod;
	if($delta_mins > $update_interval){
		if($json_data = @file_get_contents($url)){ //Suppress warnings, ja neizdodas dabūt datus
			file_put_contents($path,$json_data);
		}else{
			touch($path);//Pabakstam failu, lai nav jāmēģina atkal, ja neizdevās dabūt datus
		}
	}	
}
?>

Nezinu cik šis ir pilnīgs, bet.. Pārbauda vai strings nav tukšs un nesatur tikai atstarpes

tā funkcija tiešām ir pilnīga tādā šī vārda nozīmē kā "resna/korpulenta/uzblīdusi" jeb angliski bloated :P

omg, kā tā var rakstīt!

if(!empty($s)) {
return true;
}
else {
return false;
}

ja jau empty() izdod bool, tad to var uzreiz lietot

return !empty($s);

ja vajag pārbaudīt tikai stringu

function hasStr($s) {return trim($s) != '';}

14x rindiņas vs 1x rindiņa ;) feel the difference?

bet ja vajag vispārīgāku pārbaudi uz dažādiem datu tipiem, tad arī to var izdarīt ar 1x statement

function hasVal($v) {return (bool) (is_string($v) ? trim($v) : $v);}  // has value - checks if $v has value

pieņemsim, ka šī ir mana funkcija šim topikam ;)

test it...

foreach (array(null, true, false, 0, 123, '', ' ', 'asdf', array()) as $v) echo (hasVal($v) ? 'true' : 'false') . '<br />';
/*
false
true
false
false
true
false
false
true
false
*/

vsp par tādiem nosaukumiem kā "navTukss()" - tas ir kkādā lv mentalitātes stilā 4erez noliegumu noliegšanu. imho, labāk definēt daudzmaz konstruktīvi "irVertiba()" vai "navVertiba()" (choose atkarībā no biežākā usage)

1. pārvērš baitus normālos lielumos

2. izveido SEO stringu

function mksize($bytes) {
   $symbol = array('B', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB');
   $exp = $converted_value = 0;
   if ($bytes > 0) {
       $exp = floor(log($bytes) / log(1024));
       $converted_value = $bytes / pow(1024, floor($exp));
   }
   return sprintf('%.2f '.$symbol[$exp], $converted_value);
}

function seo_string($str, $separator = '-') {
   setlocale(LC_ALL, 'en_US.UTF8');
   return str_replace(' ', $separator, trim(preg_replace('/[^ A-Za-z0-9_]/', ' ', trim(iconv('UTF-8', 'ASCII//TRANSLIT', preg_replace('/[ -]+/', '-', $str))))));
}

Šitā dažkārt ir bijusi reāli useful:

// (:
function doNothing()
{
return 1;
}

Nopietni.

Kavacky, ja tā, tad lūdzu pielietojuma piemērus studijā! :)

Rekursīva funkcija, lai arī N reizes var neko nedarīt.

function doNothing($i){
