好的，我有一个制作签名的网站。但是因为一些头文件问题我不得不把它放在另一个文件中并使用echo。这是代码：
<h1>Create your European Trucking signatures</h1>
<?php
echo '<img src="SigGen.php?player=$Playername&score=$Score&money=$Money" />';
?>
</div>
但它显示了一个破碎的图像。但是当我转到 SigGen.php 本身时，它确实显示如下：
http
://european-trucking.com/SigGen.php?player_name=Thimo 这是 SigGen 的代码：
<?
/*
***Made by: Nodroz***
*** Enjoy your signatures! ***
*/
$username="10528_Thimo"; //Your MySQL Username.
$password="*********"; // Your MySQL Pass.
$database="10528_Thimo"; // Your MySQL database.
$host="95.211.***.***"; // Your MySQL host. This is "localhost" or the IP specified by your hosting company.
$player_name=$_GET['player_name']; // This gets the player his name from the previous page.
/* Next, we will make a connection to the mysql.
If it can't connect, it'll print on the screen: Unable to select database. Be sure the databasename exists and online is. */
mysql_connect($host,$username,$password); // Connection to the database.
@mysql_select_db($database) or die( "Unable to select database. Be sure the databasename exists and online is."); //Selection of the database. If it can't read the database, it'll give an error.
/* To protect MySQL injection. */
$player_name = stripslashes($player_name);
$player_name = mysql_real_escape_string($player_name);
$query="SELECT * FROM Users WHERE Name='$player_name'"; // Gets all the information about the player.
$result=mysql_query($query);
$i=mysql_num_rows($result); // Here we are counting how many rows this result gives us.
/* We will now put the player's information into variables so we can use them more easily. */
/* DON'T FORGET: The names should be exact the same as in your mysql db.*/
if ($i == 1) // If the user has been correct, then it'll give us 1 row. If its 1 row, then it'll proceed with the code.

$text_username = "$Playername"; // This gets the information: player name to be showed in the picture.
$text_score = "$Score"; // Same as above but with score.

imagettftext($im, 16, 0, 5, 20, $text_color, $font, $text_username); // Prints the username in the picture.
imagettftext($im, 16, 0, 5, 40, $text_color, $font, "Score:");

imagepng($im);
imagedestroy($im);
} else echo('Username is not in our database. Please try again.'); // If the username doesn't exist (so the row is 0) then it'll give en error.
mysql_close();
?>
任何人都知道为什么它不使用回声显示为图像？
