You might be better to catch the output into a file and then decide if you need to send it. Your code may well return a
No rows found type message and email it every run whether there is anything interesting or not. It might even cause you problems if you try to send nothing.
- What output do you get from the mysql command?
- What is the condition to send or not?

Robin

mysqlnd_uh_set_connection_proxy
MYSQLND_UH_SET_CONNECTION_PROXY(3) 1 MYSQLND_UH_SET_CONNECTION_PROXY(3)
mysqlnd_uh_set_connection_proxy - Installs a proxy for mysqlnd connections
SYNOPSIS
bool mysqlnd_uh_set_connection_proxy (MysqlndUhConnection &$connection_proxy, [mysqli &$mysqli_connection])
DESCRIPTION
Installs a proxy object to hook mysqlnd's connection objects methods. Once installed, the proxy will be used for all MySQL connections
opened with mysqli, mysql or PDO_MYSQL, assuming that the listed extensions are compiled to use the mysqlnd library.
The function can be disabled with mysqlnd_uh.enable. If mysqlnd_uh.enable is set to FALSE the function will not install the proxy and
always return TRUE. Additionally, an error of the type E_WARNING may be emitted. The error message may read like PHP Warning:
mysqlnd_uh_set_connection_proxy(): (Mysqlnd User Handler) The plugin has been disabled by setting the configuration parameter
mysqlnd_uh.enable = false. The proxy has not been installed [...].
PARAMETERS
o $connection_proxy
- A proxy object of type MysqlndUhConnection.
o $mysqli_connection
- Object of type mysqli. If given, the proxy will be set for this particular connection only.
RETURN VALUES
Returns TRUE on success. Otherwise, returns FALSE
EXAMPLES
Example #1
mysqlnd_uh_set_connection_proxy(3) example
<?php
$mysqli = new mysqli("localhost", "root", "", "test");
$mysqli->query("SELECT 'No proxy installed, yet'");
class proxy extends MysqlndUhConnection {
public function query($res, $query) {
printf("%s(%s)
", __METHOD__, var_export(func_get_args(), true));
$ret = parent::query($res, $query);
printf("%s returns %s
", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli->query("SELECT 'mysqlnd rocks!'");
$mysql = mysql_connect("localhost", "root", "", "test");
mysql_query("SELECT 'Ahoy Andrey!'", $mysql);
$pdo = new PDO("mysql:host=localhost;dbname=test", "root", "");
$pdo->query("SELECT 'Moin Johannes!'");
?>
The above example will output:
proxy::query(array (
0 => NULL,
1 => 'SELECT 'mysqlnd rocks!'',
))
proxy::query returns true
proxy::query(array (
0 => NULL,
1 => 'SELECT 'Ahoy Andrey!'',
))
proxy::query returns true
proxy::query(array (
0 => NULL,
1 => 'SELECT 'Moin Johannes!'',
))
proxy::query returns true
