Php Foreach在一次迭代中重复两次

我有这个阵列：

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

这是我循环它的代码：

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

结果是：

apple
ADV
orange
peach

如何更改代码以获得此结果

apple
ADV
strawberry
orange
peach

移除else块并回显所有水果

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

}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;

}
