问题:

php判断变量是否含有(包括)特定字符串

假如有变量
$liehuo_net="123456789.exe"

如何让程序做如下判断:

若$liehuo_net中有“exe”,则输出“EXE”

若无“exe”则判断是否有“123”
若有“123”则输出“一二三”

若无,则输出“全无”

回答:


$liehuo_net="123456789.exe";

if(strstr($liehuo_net,"exe"))
{
echo "exe\n";
}
elseif(strstr($a,"123"))
{
echo "一二三\n";
}
else
{
echo "全无";
}

?>
