陣列Array的常用功能

建立陣列(Array):

方法1:

$newArray = array("值","值","值")

方法2:

$newArray = array(1=>"值",2=>"值",3=>"值")

方法3:

$newArray = array("標籤1"=>"值","標籤2"=>"值","標籤3"=>"值")

方法4:

$newArray = array("標籤1"=>"值","標籤2"=>array("標籤2_1"=>"值","標籤2_2"=>"值","標籤2_3"=>"值"),"標籤3"=>"值")

方法5:

$newArray = array()

$newArray[1] = 值

$newArray[2] = 值

$newArray[3] = 值

方法6:

$newArray = array()

$newArray["標籤1"] = "值"

$newArray["標籤2"] = "值"

$newArray["標籤3"] = "值"

排序陣列

從值來排序 

asort($newArray); //由小到大

arsort($newArray); //由大到小

從標籤排序

ksort($newArray); //由小到大

krsort($newArray); //由大到小
