Question

我无法弄清楚为什么$ promobill（$ count_i）不会打印任何内容。我已经和他一起工作了好几个小时，把头靠在墙上。有什么想法吗？

$ promobill是不是一个数组？它应该是，但我不确定它是否正确形成。这行是否会从原始数组中产生一个随机元素数组，或者只产生一个随机元素并将其赋值给变量$ promobill？

$promo_bill = array_rand($site_promotions, $app_count);

这是我的完整代码：

    <?php

$site_promotions = array(
    'Free appetiser - orders over $3,000',
    '$100 off first time orders!',
    'testing...'
);

$appetisers = array(
    array('Pomegranate Shrimp','Jumbo shrimp sauteed with shitake mushrooms, herbs and pomegranate molasses.','#'),
    array('Hummus','Chick peas blended with tahini, garlic and lemon juice; topped with olive oil.','#'),
    array('Baba Ghannouj','Roasted eggplant blended with tahini, fresh garlic, parsley and lemon juice; topped with olive oil.','#'),
    array('Persian SaladPersian Salad','Freshly diced cucumbers, tomatoes and red onions tossed with lemon juice and a pinch of mint.','#'),
    array('Kash-Ke-Bademjan','Roasted eggplant purees with onion, garlic, mint and Kashk (aged, dried yogurt); topped with caramelized onions and kask.','#'),
    array('Must O Khiar','Homemade yogurt, freshly diced cucumbers and mint. Smooth and refreshing!','#'),
    array('Moosir','Persian Shallot finely sliced mixed with thich homemade yogurt. Try it, you\'ll like it.','#'),
    array('Olovieh','Persian potato salad with chopped chicken breast, pickles, peas, shredded carrots & mayonnaise.','#'),
    array('Caspian Eggplant','Mix of sweet charbroiled eggplant, tomato, onion & garlic topped with moosir.','#'),
    array('Pomegranate Mushrooms','Your choice of mushrooms flavored with exotic herbs, garlic, olive oil & pomegranate molasses.','#'),
    array('Dolmeh Felfel','Two bell peppers stuffed with basmati rice, cracked wheat, herbs & vegtables, baked in tomato saffron sauce.','#'),
    array('Dolmeh','Grape leaves stuffed with rice, tomato, onion, herbs & spices in tomato saffron sauce.','#'),
    array('Borani','Fresh spinach sautéed with onions and garlic in extra virgin olive oil and mixed with homemade yogurt.','#'),
    array('Spicy Pomegranate Wings','Charbroiled chicken wings with pomegranate glaze (7). Yummy, yummy, yummy!','#'),
    array('Falafel','Chickpeas seasoned and lightly fried served with tahini sauce.','#'),
    array('Persian Garden Salad','Crispy romaine, spring mix, red onions, cucumbers, cherry tomato, olives & Bulgarian cheese.','#')
);

$app_count = count($appetisers);
$promo_bill = array_rand($site_promotions, $app_count);

foreach($appetisers as $dish)
    {
        $count_i=key($dish);

        echo'
            <div class="sponsor" title="Click to flip">

foreach (explode("\n", file_get_contents('http://donyacatering.com/st/wp-content/themes/DonyaCatering/data/promotions.txt')) as $promotions1) {

Answer 2

不是试图为每道菜建立一系列促销活动，为什么不简单地为每个项目获得一个促销活动？

foreach ($appetisers as $dish) {
    $promotion = $site_promotions[array_rand($site_promotions, 1)];
    // use $promotion
}

你似乎在计算数组开胃菜，然后尝试将这个计数用于site_promotions，而不是它应该是dbe：

$app_count = count($site_promotions);
$promo_bill = array_rand($site_promotions, $app_count);

我的代码被数组打破了，但我无法理解
