Incrementing / Decrementing Operators

artırma operatörü

-- eksiltme operatörü

Example    Name              Effect
---------------------------------------------------------------------
  $a       Pre-increment     Increments $a by one, then returns $a.
$a         Post-increment    Returns $a, then increments $a by one.
--$a       Pre-decrement     Decrements $a by one, then returns $a.
$a--       Post-decrement    Returns $a, then decrements $a by one.

Bu değişkenin önüne veya arkasına gidebilir.

Eğer değişkenin önüne koyarsanız, arttırma / azaltma işlemi değişken için yapılırilko zaman sonuç verir. Eğer değişken sonra koyarsanız, değişkendirilkdöndü, sonra arttırma / azaltma işlemi yapılır.

Örneğin:

$apples = 10;
for ($i = 0; $i < 10;   $i){
    echo 'I have ' . $apples-- . " apples. I just ate one.\n";
}

Live example

Yukarıdaki durumda $i daha hızlı olduğu için kullanılır. $i aynı sonuçlar olurdu.

Ancak, elma sayısı görüntülemek için . $apples-- beri ilk kullanmalısınız ^strong>sonrabu kadar kaldı.

Ayrıca PHP mektuplar artış:

$i = "a";
while ($i < "c"){
    echo $i  ;
}

z ulaşıldığında aa gelecek ve bu böyle devam eder.

Karakter değişkenleri artan ama indirildiği ve bu yüzden sadece düz hatta ASCII karakter olabilir not (a-z ve A-Z) desteklenmektedir.
