php：对象的数组（2）
一、代码一
1、“代码一”的源码
<?php
class NUM
{
public $number="";
public $number_class="";
}
class obj
{
public $v1 = "";
public $v2 = "";
}
for($i=0; $i<10; $i++)
{
$cat[$i] = new obj;
$nm[$i] = new NUM;
$nu[$i] = new NUM;
$nm[$i] -> number=$i;
$nm[$i] -> number_class = "red";
$nu[$i] -> number=$i*2;
$nu[$i] -> number_class = "green";
// 将“对象”赋予“成员变量”
$cat[$i]->v1 = $nm[$i];
$cat[$i]->v2 = $nu[$i];
}
foreach($cat as $ct)
{
echo "v1-number=" . $ct->v1->number ." v1-class=". $ct->v1->number_class . "\t";
echo "v2-number=" . $ct->v2->number ." v2-class=". $ct->v2->number_class . PHP_EOL;
}
?>
