Changing images with php

[MetalAxeToby]

So i have this code wich checks if my server is online:

 

<?php
$ip = "example.com"; //IP or web addy
$port = "80"; //Port

$sock = @fsockopen( $ip, $port, $num, $error, 2 ); //2 is the ping time, you can sub what you need

//Since fsockopen function returns TRUE or FALSE we can just plug it into the IF/THEN statement. An IF/ELSE would have worked to

if( !$sock ){

//Do this if it is closed
    echo( "offline" );
    
}

if( $sock ){

//Do this if it is open
    echo( "online" );
    fclose($sock);

}
        ?>

 

and i've got:

 

<img class="img-circle" src="ico/online.png" alt="Server status">

 

I want to use the php script to change the image source in the html.I have an online.png and an offline.png image.I need to somehow change it and I don't know how. I am fairly new to php.

<?php


if( !$sock ){


//Do this if it is closed

    echo( "offline" );

    $image = 'offline.png';


}


if( $sock ){


//Do this if it is open

    echo( "online" );

    fclose($sock);

    $image = 'online.png';


}


?>


<img class="img-circle" src="ico/<?php echo $image; ?>" alt="Server status">
