将中断放入写在图像上的文本中

问题描述：

If i write a text on a picture with code below, code tries to type all the text in one line. So text overflows out of the image like in picture1. I want to write it like in picture2.

If there is a function in php which enables writting like in picture2 what is it?
If there is no function to do that, how can i do it by writting my code? Can you give me a clue?

$text = $_POST['text']; // Text comes from a form.

$im = @imagecreate(700, 350)
    or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagettftext($im, 22, 0, 5, 25,  $text_color, 'fonts/COOLVETICA RG.TTF', properText($text));
imagepng($im, 'image.png');

Picture1:

Picture one

Picture2:

enter image description here

如果我在下面带代码的图片上写文字，代码会尝试在一行中输入所有文字。所以文字溢出图像，如图1所示。我想在picture2中编写它。 p>

如果在php中有一个函数可以像在picture2中那样写入它是什么？
如果没有这样做的功能，我怎么能写我的代码呢？你能给我一个线索吗？ p>

  $ text = $ _POST ['text'];  //文本来自一个表单。
 
 $ im = @imagecreate（700,350）
或者死（“无法初始化新的GD图像流”）; 
 $ background_color = imagecolorallocate（$ im，0,0  ，0）; 
 $ text_color = imagecolorallocate（$ im，233,14,91）; 
imagettftext（$ im，22,0,5,25，$ text_color，'fonts / COOLVETICA RG.TTF'，properText（$  text））; 
imagepng（$ im，'image.png'）; 
  code>  pre> 
 
  
  Picture1： p> 
  blockquote  > 
 
 
  p> 
 
 
 
 \  n  
 图片2： p> 
  blockquote> 
 
 
  p> 
  div>

答

Put it in a bounding box using imagettfbbox() then the text will wrap. There's a full example on php.net:
