我刚刚完成了这个脚本的工作,我需要在同一页面中多次使用它。但是,当我第二次使用它时,我收到错误 Fatal error: Cannot redeclare get_names() (previously declared. 我环顾四周寻找答案,但我能找到的只是使用 once 命令,但它似乎不起作用用 get. 这是脚本:
<?php
$db = mysql_connect('localhost', 'username', 'pass') or die("Database error");
mysql_select_db('dbname', $db);
$query = "SELECT pool FROM winners";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result))
if ($row['pool'] % 2) {
echo "<h4>Result 1</h4>";
$names = get_names(1);
foreach($names as $name) {
echo $name . "<br/>";
}
} else {
echo "<h4>Result 2</h4>";
$names = get_names(0);
foreach($names as $name) {
echo $name . "<br/>";
}
}
function get_names($pool_result)
{
$name_array = array();
$query = "SELECT * FROM comments WHERE commentid % 2 = $pool_result";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result)) {
array_push($name_array, $row['name']);
}
return $name_array;
} ?>
