Create image PHP

Question

如何讓php創建一個這樣的圖像？

（顯然，如果沒有文字，邊框，線條，箭頭）。

你可以使用GD庫。

// Load the three image files: 
$images[1]=imagecreatefromjpeg("file1.jpg"); 
$images[2]=imagecreatefromjpeg("file2.jpg"); 
$images[3]=imagecreatefromjpeg("file3.jpg"); 
// Determine their dimensions. 
$totalx=$totaly=0; 
for ($ix in $images) { 
    $img=$images[$ix]; 
    $totalx+=imagesx($img); // get total width 
    $totaly=max($totaly,imagesy($img)); // get maximum height 
} 
$xm=20; // side and in-between margin 
$ym=20; // top and bottom margin 
$totalx+=$xmargin*4; // 2 for the outsides and 2 for the in-betweens 
$totaly+=$ymargin*2; // for top and bottom 
$i=imagecreatetruecolor($totalx,$totaly); 
$xstart=0; // where to place the next image 
for ($ix in $images) { 
    $img=$images[$ix]; 
    $xstart+=$imagesx($img)+$xm; // increase by this image's width plus buffer 
    imagecopy($i,$img,$xstart,$ym,0,0,imagesx($img),imagesy($img)); 
} 
imagepng($i); // this outputs the image data. if you want to write it to a file you can do that with imagepng($i,$filename).
