PHP foreach获取迭代索引

Question

I'm trying to display results in a foreach loop.

I have an array like so:

$slides = array(
    1 => $params->get('param_1'), 
    2 => $params->get('param_2'),
    3 => $params->get('param_3')
);

If a parameter in the backend is set to yes , the value equals 1 , and thus a result is displayed.

So what I'm trying to write is, foreach array value that is equal to 1

I'm aware that I can't use something like this:

foreach (slides == 1) { 
    // echo stuff here
}

How would I write this foreach loop? Any help or guidelines would be highly appreciated

Answer 1

foreach ( $slides as $slide ) { 
    if ( $slide != 1 ) continue;
    // echo stuff here
}
