Parâmetros

image: Um objeto GdImage, retornado por uma das funções de criação de imagem, como imagecreatetruecolor().
x1: Coordenada x do ponto 1.
y1: Coordenada y do ponto 1.
x2: Coordenada x do ponto 2.
y2: Coordenada y do ponto 2.
color: A cor de preenchimento. Um identificador de cor criado com imagecolorallocate().

Valor Retornado

Retorna true em caso de sucesso ou false em caso de falha.

Registro de Alterações

Versão	Descrição
8.0.0	O parâmetro `image` agora espera uma instância de GdImage; anteriormente, um resource `gd` válido era esperado.

Exemplos

Exemplo #1 Uso de imagefilledrectangle()

<?php
// Cria uma imagem 55x30
$im = imagecreatetruecolor(55, 30);
$white = imagecolorallocate($im, 255, 255, 255);

// Desenha um retângulo branco
imagefilledrectangle($im, 4, 4, 50, 25, $white);

// Grava a imagem
imagepng($im, './imagefilledrectangle.png');

If you want to draw a rectangle with rounded corners, you can use this simple function... 
Rectangle starts at x1y1 and ends at x2y2. $radius defines radius of circled corner. 

<?

function ImageRectangleWithRoundedCorners(&$im, $x1, $y1, $x2, $y2, $radius, $color) {
// draw rectangle without corners
imagefilledrectangle($im, $x1+$radius, $y1, $x2-$radius, $y2, $color);
imagefilledrectangle($im, $x1, $y1+$radius, $x2, $y2-$radius, $color);
// draw circled corners
imagefilledellipse($im, $x1+$radius, $y1+$radius, $radius*2, $radius*2, $color);
imagefilledellipse($im, $x2-$radius, $y1+$radius, $radius*2, $radius*2, $color);
imagefilledellipse($im, $x1+$radius, $y2-$radius, $radius*2, $radius*2, $color);
imagefilledellipse($im, $x2-$radius, $y2-$radius, $radius*2, $radius*2, $color);
}

?>

I wanted to clear an image, and set it to full transparent.

imagefilledrectangle() seems to ignore alpha channel and alpha blending.

Use imagefill() instead:



<?php

$w = imagesx($final);

$h = imagesy($final);

$grande = imagecreatetruecolor($w, $h);



// Alpha blending on to use channel alpha

imagealphablending($grande, true);

// Allocate a transparent color and fill the new image with it.

// Without this the image will have a black background instead

// of being transparent.

$transparent = imagecolorallocatealpha($grande, 0, 0, 0, 127);

// transparent alpha will be _ignored_:

imagefilledrectangle($grande, 0, 0, $w, $h, $transparent);

// ok, transparent will be used and set whole alpha channel to transparent:

imagefill($grande, 0, 0, $transparent);

?>

I've made a function to make full color gradients:

<?php

// The image must be in truecolor mode!!
    function gradient_region($img, $x, $y, $width, $height,$src_color, $dest_color=0){
        $src_alpha = ($src_color) >> 24;
        $src_red = ($src_color & 0xFF0000) >> 16;
        $src_green = ($src_color & 0x00FF00) >> 8;
        $src_blue = ($src_color & 0x0000FF);
        
        $dest_alpha = ($dest_color) >> 24;
        $dest_red = ($dest_color & 0xFF0000) >> 16;
        $dest_green = ($dest_color & 0x00FF00) >> 8;
        $dest_blue = ($dest_color & 0x0000FF);
            
            
        $inc_alpha = ($dest_alpha - $src_alpha) / $width;
        $inc_red = ($dest_red - $src_red)/$width;
        $inc_green = ($dest_green - $src_green)/$width;
        $inc_blue = ($dest_blue - $src_blue)/$width;
        
        // If you need more performance, the step can be increased
        for ($i=0;$i<$width;$i++){
            $src_alpha += $inc_alpha;
            $src_blue += $inc_blue;
            $src_green += $inc_green;
            $src_red += $inc_red;
            imagefilledrectangle($img,
                $x+$i,$y,         
                $x+$i,$y+$height,
                imagecolorallocatealpha($img,
                $src_red,$src_green,$src_blue,$src_alpha));
        }
    }
?>

Important quirk to note:



While imagerectangle will allow you to use a different order of your coordinates (such as bottom-left to upper-right), imagefilledrectangle will only work correctly if you use top-left to bottom-right as indicated in the docs.

Thanks terereese. it took me over two hours to figure that one out.
it worked locally: imagefilledrectangle(imagresource, int x1, int x2, int y1, inty2, color)

BUT remote on my provider only this worked: imagefilledrectangle(imagresource, int x1, int y2, int x1, inty1, color)

Any ideas why and where?
