如何将数组中的文本与字符串匹配,如果为true则返回其值?

I'm trying to understand how I can match an array against a line of text, if the text inside the array is found, then I'd like to return that value.

I've tried the following but nothing seems to get returned.

$catArray = array(
    '0' => 'breakfast',
    '1' => 'lunch',
    '2' => 'dinner',
);

$text = 'It is your breakfast';

foreach($catArray as $cat){
    if(strpos($cat, $text) !== false){
        return $cat;
    }
}

By this logic, breakfast should return.

        '1' => 'lunch',
        '2' => 'dinner',
    );
    $text = 'It is your breakfast';
    
    foreach($catArray as $cat){
        if(strpos($text, $cat) !== false){
            echo $cat;
        }
    }
    

    returns breakfast

    so basically turn around the haystack and the needle
