Give border to image created in PHP

Question

How do I give a border to an image created using PHP?

Answer 1

function drawBorder(&$img, &$color, $thickness = 1) 
{
    $x1 = 0; 
    $y1 = 0; 
    $x2 = ImageSX($img) - 1; 
    $y2 = ImageSY($img) - 1; 

    for($i = 0; $i < $thickness; $i++) 
    { 
        ImageRectangle($img, $x1++, $y1++, $x2--, $y2--, $color); 
    } 
}

Then the usage would just to do.

$color = imagecolorallocate($img, 255, 0, 0);
drawBorder($img,$color, 255);
