$arrayName1 = array(1 => 0.1);
$arrayName2 = array(1 => 0.1, 2 => 0.1);
$arrayName3 = array(1 => 0.2, 2 => 0.1, 3 => 0.1);
$arrayName4 = array(1 => 0.2, 2 => 0.1, 3 => 0.1, 4 => 0.1);
for ($i=1; $i <=4 ; $i++) {
$rate = ${'arrayName'.$i};
//循环
print_r($rate);
}
结果：
Array
(
=> 0.1
)
Array
(
=> 0.1
=> 0.1
)
Array
(
=> 0.2
=> 0.1
=> 0.1
)
Array
(
=> 0.2
=> 0.1
=> 0.1
=> 0.1
)
