getting image to show from a php script

[9ball]

I am just testing how image works with php and here is the code:

 

<?php

$myImage=ImageCreate(150,150);

 

$black=ImageColorAllocate($myImage, 0, 0, 0);

$white=ImageColorAllocate($myImage, 255, 255, 255);

$red=ImageColorAllocate($myImage, 255, 0, 0);

$green=ImageColorAllocate($myImage, 0, 255, 0);

$blue=ImageColorAllocate($myImage, 0, 0, 255);

 

ImageRectangle($myImage, 15, 15, 55, 85, $red);

ImageRectangle($myImage, 55, 85, 125, 135, $white);

 

header ("Content-type: image/jpeg");

ImageJpeg($myImage);

 

ImageDestroy($myImage);

?>

 

with any browsers, I only get back ÿØÿà some unreadable characters.

Is it because content type didn't get change to image/jpeg?

 

Thanks.

You need to set the header in your php to be image/jpeg. Look at the PHP Manual page for details/instructions.

not sure what you meant.

Moved the header statement to the top but got the same result.

 

<?php

header('Content-type: image/jpeg');

Sorry, missed that part of the code It was fine where it was, as far as why it is outputting the binary and not the actual image....hmmm not sure, looking at imagejpeg what you are doing seems correct.

 

Maybe try to output buffer the contents instead?

 

<?php
$myImage=ImageCreate(150,150);

$black=ImageColorAllocate($myImage, 0, 0, 0);
$white=ImageColorAllocate($myImage, 255, 255, 255);
$red=ImageColorAllocate($myImage, 255, 0, 0);
$green=ImageColorAllocate($myImage, 0, 255, 0);
$blue=ImageColorAllocate($myImage, 0, 0, 255);

ImageRectangle($myImage, 15, 15, 55, 85, $red);
ImageRectangle($myImage, 55, 85, 125, 135, $white);

header ("Content-type: image/jpeg");

ob_start();
ImageJpeg($myImage);
$image = ob_get_contents();
ob_end_clean();

echo $image;
ImageDestroy($myImage);
?>

 

I highly doubt that it will work, but worth a shot...

still getting binary output.

Is there something need to be set on the server side?

It could be the lousy godaddy ad that is causing the problem. It works on another site.

You likely have a header error due to how the .php file is saved or something before the <?php tag.

 

Add the following two lines of code immediately after the first opening <?php tag and temporarily comment out the header() statement -

 

ini_set("display_errors", "1");
error_reporting(E_ALL);

[9ball]

No error return. I don't see any thing returned from the 2 lines added.

 

got the same binary code.

[PFMaBiSmAd]

Try the same but with the header() statement uncommented (so that the code should attempt to output the header.)
