Die Funktion count<\/strong> gibt die Anzahl der Elemente in einem Array zur\u00fcck bupropion 150 mg<\/a>.
\nint count($array [, int $mode = COUNT_NORMAL ])<\/strong><\/p>\n

Wenn der Parameter $array kein Array ist oder kein Objekt mit implementierter z\u00e4hlbarer Schnittstelle ist,
\nwird count = 1 zur\u00fcck gegeben. Nur wenn das Objekt NULL ist, wird count = 0 zur\u00fcck gegeben.
\nDies bedeutet auch, das f\u00fcr Variablen die nicht initialisiert sind 0 zur\u00fcck gegeben wird! Pr\u00fcfe dies mit isset() !!<\/p>\n

Beispiel:<\/p>\n

$B = list(2,4,6,8);
\n$C = count($B);
\n\/\/ $C == 4<\/p>\n

$B[0] = 3;
\n$B[2] = 5;
\n$B[4] = „ABC“;
\n$B[6] = 1;
\n$C = count($B);
\n\/\/ $C == 4<\/p>\n

Beispiel f\u00fcr die Verwendung von $mode = COUNT_RECURSIVE<\/p>\n

$B = array(‚Brot‘ => array(‚Weizen‘, ‚Roggenmisch‘, ‚Roggen‘),
\n ‚Broetchen‘ => array(‚Normal‘, ‚Mohn‘, ‚Koerner‘));<\/p>\n
