在这里，我正在尝试为图像添加边框，该图像使用 imagettftext() 函数从用户输入文本转换为图像。任何人都知道我将如何实现这一点。

Bellow 是我用来将文本转换为图像的示例 php 代码。

<?php session_start();
  header("Content-type: image/png");
$myArray = explode(',', $_GET['img']);  
$fontarray = explode(',' , $_GET['fontsize']);   
$align =$_GET['align'];


####################### BEGIN USER EDITS #######################   
$imagewidth = 1000;
$imageheight = 1000;
$fontangle = "0";
$font = "Outlinesten_6.ttf";
$backgroundcolor = "FFFFFF";
$textcolor = "#000000";

### Convert HTML backgound color to RGB
if( @eregi( "([0-9a-f]{2})([0-9a-f]{2})([0-9a-f]{2})", $backgroundcolor, $bgrgb ) )
{$bgred = hexdec( $bgrgb[1] );   $bggreen = hexdec( $bgrgb[2] );   $bgblue = hexdec( $bgrgb[3] );}

### Convert HTML text color to RGB
if( @eregi( "([0-9a-f]{2})([0-9a-f]{2})([0-9a-f]{2})", $textcolor, $textrgb ) )
{$textred = hexdec( $textrgb[1] );   $textgreen = hexdec( $textrgb[2] );   $textblue = hexdec( $textrgb[3] );}

### Create image
$im = imagecreate( $imagewidth, $imageheight );

### Declare image's background color
$bgcolor = imagecolorallocate($im, $bgred,$bggreen,$bgblue);

### Declare image's text color
$fontcolor = imagecolorallocate($im, $textred,$textgreen,$textblue);

       $box = imageTTFBbox($fontarray[$j],$fontangle,$font,$myArray[$i]);    

### Get width of text from dimensions
$textwidth = abs($box[4] - $box[0]);      

### Get height of text from dimensions
$textheight = abs($box[5] - $box[1]);

### Get x-coordinate of centered text horizontally using length of the image and length of the text
//$xcord = ($imagewidth/2)-($textwidth/2)-2;


        $price= GetPrice($fontarray[$j],$myArray[$i]);
