<2 ist gleich wie =<3

Nein, das ist eine Differenz von 2.

[querschlaeger]

<2 ist gleich wie =<3

<4 ist das selbe wie <=3

oder

<2 ist das selbe wie <=1

So wird wird ein Schuh drauß (natürlich alles bezogen auf ganze Zahlen ℤ).

ups, habe was vertauscht es müsste dieses zeichen sein >
UPPPPSSSS

PHP-Code:

for($i=0; $i>2; $i++)
{
//Code
}

Nein Marti,

es muss so lauten:

PHP-Code:

for($i=0; $i<=2; $i++)
{
//Code
}


Oder für Menschen lesbarer so:

PHP-Code:

for($i=1; $i<=3; $i++)
{
//Code
}


Bitte, teste es selbst.

Mh, klappt leider nicht. Es werden bei Einbau keine Threads mehr erstellt, wenn ich die Schleife rausnehme, geht es wieder.

Hier sucht er ja alle News im Feed herraus. Ich habe es an verschiedenen Stellen versucht, leider ohne Erfolg, es wird dann kein Thread erstellt.

Hier die originale Datei:
