MySQL-计算php中的总行数 [英] MySQL - count total number of rows in php

问题描述

在没有应用任何条件的情况下，对表中的行总数进行计数的最佳MySQL命令是什么?我正在通过php执行此操作，所以也许有一个php函数可以为我执行此操作?我不知道.这是我的php的示例:

What is the best MySQL command to count the total number of rows in a table without any conditions applied to it? I'm doing this through php, so maybe there is a php function which does this for me? I don't know. Here is an example of my php:

<?php
$con = mysql_connect("server.com","user","pswd");
if (!$con) {
  die('Could not connect: ' . mysql_error());
}

mysql_select_db("db", $con);

$result = mysql_query("some command");
$row = mysql_fetch_array($result);

mysql_close($con);
?>

推荐答案

<?php
$con = mysql_connect("server.com","user","pswd");
if (!$con) {
  die('Could not connect: ' . mysql_error());
}

mysql_select_db("db", $con);

$result = mysql_query("select count(1) FROM table");
$row = mysql_fetch_array($result);

$total = $row[0];
echo "Total rows: " . $total;

mysql_close($con);
?>
