[英]Select count(column) from table of mysql in php
I have a database and I am trying to make a website and connect it to my database.我有一个数据库,我正在尝试创建一个网站并将其连接到我的数据库。 I am trying to count the number of instances in a column but I am having trouble.
我正在尝试计算列中的实例数,但我遇到了麻烦。 I have this so far:
到目前为止我有这个:
$result =("SELECT COUNT(mediaID) FROM media WHERE 1;");
echo "The number of media posted on the system is ".$result."<br>";
I hope you have the connection done.我希望你已经完成了连接。 Here something is column which you are using to filter the output as desired.
这是您用来根据需要过滤 output 的列。
$result="select count(mediaID) from media where something="1"";
echo" the sentence".$result"."
