第十三天数组和数组循环

创建数组

$arr =array ();

$arr= [];

创建索引数组

$arr = [

'欧阳大仙',

'法力无边',

'武功盖世',

]

访问输出

echo $arr[0];

echo $arr[1];

echo $arr[2];

创建关联数组

$arr = [

'oy' =>'欧阳大仙',

'fl' =>'法力无边',

'wg' =>'武功盖世',

]

访问输出

echo $arr['oy'];

echo $arr['oy'];

echo $arr['oy'];

二维数组

$arr = array (

$arr = array (

'oy' =>'欧阳大仙',

'fl' =>'法力无边',

'wg' =>'武功盖世',

)

//变三维

'js; =>[

'举世无双',

'一统江湖',

]

)

多维数组循环

foreach （$arr as $key => $v）{

foreach ( $v as $key => $value) {

echo $value

echo '<hr>'

}

}

foreach ($arr as $key => $v ){

foreach ($v['js'] as $vv ){

echo $vv ;

}

}
