strange problem

[kusal]

Hi,

This is a really strange problem

<?php
// Set the content-type
header("Content-type: image/png");

// Create the image
$im = imagecreatetruecolor(400, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);

$text = utf8_encode(" ’ ");
// Replace path by your own font path
$font = 'arial.ttf';

// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

’

- right single qoute , server could not recognized it, so it displays a BOX character in the image.

Can anyone help me.

Thank you

Have you tried it without the utf8_encode()?

Yes, it's not working 🙁

Hi,

I think you can solve the problem by replacing the character with its numeric entity. The gd library supports numeric entities instead of encoding dependent characters.

Something like this should work (if the mbstring extension is enabled):

<?php
// Set the content-type
header("Content-type: image/png");

// Create the image
$im = imagecreatetruecolor(400, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);

$text = mb_encode_numericentity(" &#8217; ", array(0x80, 0xff, 0, 0xff), 'utf-8');
// or without mbsting: $text = " & #180; ";

// Replace path by your own font path
$font = 'arial.ttf';

// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

You may need to adjust the third mb_encode_numericentity argument (encoding) to the encoding of the php file (or the text).

The numeric entity of the right quote is & #180;

(remove the space between the ampersand and the #)

Thomas

Hello,

Did it work for you?, because it don't work for me 🙁

Yes,

it did work for me. As a first step, forget about the mb_encode_numericentity and enable the next line that uses the entity directly (without the whitespace between the ampersand and the #)
