PHP代碼如下：（PHP不僅可以考慮直接使用數(shù)組，也可以考慮直接查詢數(shù)據(jù)庫，獲取數(shù)據(jù)庫內(nèi)容，本代碼使用的是數(shù)組。）
?php
$provinces=array("beijing","tianjin","shanghai","chongqing","hebei","henan","heilongjiang","jilin","changchun",
"shandong","anhui","shanxi","guangzhou","yunnan","hainan","xizang","qinghai","fujian","guizhou","jiangsu",
"zhejiang","guangzhou","yunan","hainan","xizang","neimenggu","sichuan","gansu","ningxia","xianggang","aomen");
$tmp=$_GET['q'];
$val=array();
$k=0;
if (strlen($tmp)>0)
{
for($i=0;$i31;$i++){
if(strpos($provinces[$i],$tmp)!==false){
//傳遞值給val
$val[$k]=$provinces[$i];
//下標增加
$k=$k+1;
}
}
//遍歷val數(shù)組
for($j=0;$jcount($val);$j++)
{
echo $val[$j];
echo "br>";
}
}
?>
