我有以下代码:
<?php
mysql_connect("localhost","root","");
mysql_select_db("bravo");
$res=mysql_query("select * from coisas");
?>
<div>
<?php
while ($row=mysql_fetch_array($res)) {
echo "<img src=\"{$row['imagem']}\">";
}
?>
</div>
我需要在图像之间的随机位置显示一个adsense代码,任何人都可以帮助我吗?

在while中添加一些代码:
while ($row=mysql_fetch_array($res)) {
echo "<img src=\"{$row['imagem']}\">";
echo "--- adsense code here---";
}
将在每张图片后注入。
或者,如果你真的想把它放在完全随机的位置:
$chanceOfAdsense = 35; // 35% chance of adsense appearing between any given images
while ($row=mysql_fetch_array($res)) {
echo "<img src=\"{$row['imagem']}\">";
if (mt_rand(0,99) < $chanceOfAdsense) {
echo "--- adsense code here---";
}
}

从while循环构建输出数组,然后计算其中的值数。使用count(array)使用rand()计算随机数,然后迭代输出数组,并在索引与随机数匹配时使用if语句。
<?php
mysql_connect("localhost","root","");
mysql_select_db("bravo");
$res=mysql_query("select * from coisas");
?>
<div>
<?php
$output_array = array();
while ($row=mysql_fetch_array($res)) {
$output_array[] = "<img src=\"{$row['imagem']}\">";
}
//If you want the image to appear closer to middle, use fractions of $output_array
//EG: rand(count($output_array)/3, count($output_array)*2/3));
$rand_key = rand(0, count($output_array)-1);
foreach ($output_array as $key => $img) {
if ($key == $rand_key) {
//echo your adsense code
}
echo $img;
}
?>
</div>
