使用來自mysql數據庫的圖像生成PDF文件

Question

我是PHP新手，我一直在嘗試使用數據庫中的圖像創建一個PDF文件。我看過的所有教程只將圖像放在標題中（而不是從數據庫），並且只從數據庫中提取文本以放入PDF中。我正在使用FPDF創建我的PDF文件。任何指導或幫助實現此目的將不勝感激。

比方說，您有一個名爲images的表格，其中圖像URL存儲在列url的列下。您可以使用FPDF和MySQL適配器構建一個PDF的所有這樣的圖像的：

require 'fpdf/fpdf.php'; 

// DB parameters 
$host = "localhost"; 
$user = "username"; 
$pass = "password"; 
$db = "db"; 

// Create fpdf object 
$pdf = new FPDF('P', 'pt', 'Letter'); 

// Add a new page to the document 
$pdf->addPage(); 

// Try to connect to DB 
$r = mysql_connect($host, $user, $pass); 
if (!$r) { 
    echo "Could not connect to server\n"; 
    trigger_error(mysql_error(), E_USER_ERROR); 
} else { 
    echo "Connection established\n"; 
} 

// Try to select the database 
$r2 = mysql_select_db($db); 
if (!$r2) { 
    echo "Cannot select database\n"; 
    trigger_error(mysql_error(), E_USER_ERROR); 
} else { 
    echo "Database selected\n"; 
} 

// Try to execute the query 
$query = "SELECT * FROM images"; 
$rs = mysql_query($query); 
if (!$rs) { 
    echo "Could not execute query: $query"; 
    trigger_error(mysql_error(), E_USER_ERROR); 
} else { 
    echo "Query: $query executed\n"; 
} 

while ($row = mysql_fetch_assoc($rs)) { 
    // Get the image from each row 
    $url = $row['url']; 

    // Place the image in the pdf document 
    $pdf->Image($url); 
} 

// Close the db connection 
mysql_close(); 

// Close the document and save to the filesystem with the name images.pdf 
$pdf->Output('images.pdf','F');
