Foreach重复两次迭代

Question

我有这个数组：

x

这是我循环的代码：

$fruits = array('apple', 'strawberry', 'orange', 'peach');

结果如下：

foreach( $fruits as $key => $fruit ) {
    if( $key == 1 ) {
        echo "ADV";
    }
    else {
        echo $fruit;
    }
}

如何更改我的代码才能获得此结果？

apple
ADV
orange
peach

Answer 1

删除else块并回显所有水果

Answer 2

foreach( $fruits as $key => $fruit ) {
    if( $key == 1 ) {
        echo "ADV";
    }
    echo $fruit;

}

Answer 3

请尝试：

$fruits = array('apple', 'strawberry', 'orange', 'peach'); 
$inserted = array( 'ADV' ); // Not necessarily an array
array_splice( $fruits, 1, 0, $inserted ); 

foreach( $fruits as $key => $fruit ) {
        echo $fruit;

}
