后台
<?php
$query=$_REQUEST['query'];
$str="";
if(!empty($query))
if (false !== strpos($query, 'or')) {
$str="{\"options\": [\"ori 1\",\"ori 2\",\"ori 3\",\"ori 4\",\"ori 5\"]} ";
if(false !== strpos($query,'oric')){
$str="{\"options\": [\"oricon 1\",\"oricon 2\",\"oricon 3\",\"oricon 4\"]} ";
} }else if(false !== strpos($query, 'de')){
$str="{\"options\": [\"Dell 1\",\"Dell 2\",\"Dell 3\",\"Dell 4\"]} ";
}else if(false !== strpos($query, 'ro')){
$str="{\"options\": [\"royal ships\",\"Royal Caribbean\",\"Royal Cruises\",\"royal 4\"]} ";
} echo $str; ?>
strpos函数就用来检测是否含有子串
