MYSQL_NUM_ROWS(3) 1 MYSQL_NUM_ROWS(3)
mysql_num_rows - Get number of rows in result
SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. 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:
omysqli_stmt_num_rows(3)
o PDOStatement::rowCount
int mysql_num_rows (resource $result)
DESCRIPTION
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(3).
o $
result -The result resource that is being evaluated. This result comes from a call to mysql_query(3).
The number of rows in a result set on success or FALSE on failure.
Example #1
mysql_num_rows(3) 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
";
?>
Note
If you use mysql_unbuffered_query(3), mysql_num_rows(3) 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(3)
mysql_affected_rows(3), mysql_connect(3), mysql_data_seek(3), mysql_select_db(3), mysql_query(3).
