  • mysql_num_rows

    Get number of rows in result

Warning

This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

mysqli_num_rows
mysqli_stmt_num_rows
PDOStatement::rowCount

Description

int mysql_num_rows(resource result);

Retrieves the number of rows from a result set. This command is only valid for statements like SELECT or SHOW that return an actual result set. To retrieve the number of rows affected by a INSERT, UPDATE, REPLACE or DELETE query, use mysql_affected_rows.

Parameters

result

The result resource that is being evaluated. This result comes from a call to mysql_query.

Return Values

The number of rows in a result set on success or FALSE on failure.

Examples

Example 6.44 mysql_num_rows example

<?php

$link = mysql_connect("localhost", "mysql_user", "mysql_password");
mysql_select_db("database", $link);

$result = mysql_query("SELECT * FROM table1", $link);
$num_rows = mysql_num_rows($result);

echo "$num_rows Rows\n";

?>


Notes

Note

If you use mysql_unbuffered_query, mysql_num_rows will not return the correct value until all the rows in the result set have been retrieved.

Note

For backward compatibility, the following deprecated alias may be used: mysql_numrows
