php基础语法参考[总结]

1. 数组的常用操作可参考

$arr_type1 = array("a",12,1.1);
foreach($arr_type1 as $value) {
    print $value . "\n";
}
for($i = 0;$i < count($arr_type1);$i++){
    print $arr_type1[$i] . "\n";
}
//数组赋值
$empty_array = array();
$empty_array[] = 1;
$empty_array[] = "a";
$empty_array[] = array("hello"=>"a","b"=>"g");

//遍历K-V类型的数组
foreach($empty_array[2] as $k=>$v) {
    print $k . "\t" . $v . "\n" ;
}

//销毁数组
unset($empty_array);

//多维数组
$all = array("fruit"=>array("a"=>"orange","b"=>"banana"),"age"=>array(1,2));
print $all["age"][0];
