ping with php phar

Question

i want to use this script to do ping without using the exec(); or the commands that similar to it.

the problem is i get these errors:

Strict Standards: Non-static method Net_Ping::factory() should not be called statically in C:\\xampp\\htdocs\\test.php on line 3

Strict Standards: Non-static method Net_Ping::_setSystemName() should not be called statically in C:\\xampp\\php\\PEAR\\Net\\Ping.php on line 141

Strict Standards: Non-static method Net_Ping::_setPingPath() should not be called statically in C:\\xampp\\php\\PEAR\\Net\\Ping.php on line 143

Strict Standards: Non-static method PEAR::isError() should not be called statically in C:\\xampp\\htdocs\\test.php on line 4

the code on test.php

<?php
require_once "Net/Ping.php";
$ping = Net_Ping::factory();
if (PEAR::isError($ping)) {
    echo $ping->getMessage();
} else {
    $ping->setArgs(array('count' => 2));
    var_dump($ping->ping('example.com'));
}
?>

Nothing wrong, the PEAR component is just not fit for E_STRICT. The code you have is okay, but the PEAR code doesn't say the method is static, so PHP will emit an E_STRICT warning. That's not something you can really change, but you can opt to ignore it, by adjusting your error_reporting settings.

<?php
// before PEAR stuff.
$errLevel = error_reporting( E_ALL );

// PEAR stuff.
require_once "Net/Ping.php";
$ping = Net_Ping::factory();
if (PEAR::isError($ping)) {
    echo $ping->getMessage();
} else {
    $ping->setArgs(array('count' => 2));
    $result = $ping->ping('example.com');
}

// restore the original error level.
error_reporting( $errLevel );
var_dump( $result );

Here is a ping class I wrote last year when I needed to do this on a system that didn't have PEAR.

Example usage:

$ping = new ping();
if (!$ping->setHost('google.com')) exit('Could not set host: '.$this->getLastErrorStr());
var_dump($ping->send());
