How to Retrieve the Total Row Count in a MySQL Table Using PHP

Counting the total number of rows in a database table is a common task in web development. This information can be useful for various purposes, such as displaying summary statistics, pagination, and data analysis.

In PHP, MySQL provides a straightforward way to retrieve the total row count using the count(1) FROM expression. This expression counts the number of rows in a table without applying any specific conditions or filters.

Here is an example PHP code that demonstrates how to use this expression to count the total number of rows in a table:

<code class="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("select count(1) FROM table");
$row = mysql_fetch_array($result);

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

mysql_close($con);
?></code>

In this code, we establish a connection to the MySQL database, select the desired database, and execute the query. The count(1) expression returns a single row containing the total count of rows in the table. We then fetch this row and extract the count value into the $total variable. Finally, the total row count is displayed on the screen.

This method provides a simple and efficient way to retrieve the total row count in a MySQL table using PHP.
