파일 크기가 50kb 이상인 경우 이미지 크기 조정

Question

이미지 크기가 50kb 이상인 경우 어떻게 이미지 크기를 조정합니까?

이것은 현재 코드입니다.

$sess=66666; 
$images = $_FILES["photoimg"]["tmp_name"]; 
$new_images = "$sess.gif"; 
$width=200; 
//*** Fix Width & Heigh (Autu caculate) ***// 
$size=GetimageSize($images); 
$height=round($width*$size[1]/$size[0]); 
if($size[2] == 1) { 
    $images_orig = imagecreatefromgif($images); 
} else if($size[2] == 2) { 
    $images_orig = imagecreatefromjpeg($images); 
}else if($size[2] == 3) { 
    $images_orig = imagecreatefrompng($images); 
} 
$photoX = ImagesX($images_orig); 
$photoY = ImagesY($images_orig); 
$images_fin = ImageCreateTrueColor($width, $height); 
ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY); 
Imagejpeg($images_fin,"images/".$new_images); 
ImageDestroy($images_orig); 
ImageDestroy($images_fin);

filesize()을 사용하십시오. 이 같은

$sess=66666; 
$images = $_FILES["photoimg"]["tmp_name"]; 
$new_images = "$sess.gif"; 
$maxsize = 50 * 1024; // 50Kb 

if(filesize($images) > $maxsize) { 
    $width=200; 
    //*** Fix Width & Heigh (Autu caculate) ***// 
    $size=getimagesize($images); 
    $height=round($width*$size[1]/$size[0]); 
    if($size[2] == 1) { 
     $images_orig = imagecreatefromgif($images); 
    } else if($size[2] == 2) { 
     $images_orig = imagecreatefromjpeg($images); 
    }else if($size[2] == 3) { 
     $images_orig = imagecreatefrompng($images); 
    } 
    $photoX = imagesx($images_orig); 
    $photoY = imagesy($images_orig); 
    $images_fin = imagecreatetruecolor($width, $height); 
    imagecopyresampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1,   $photoX, $photoY); 
    imagejpeg($images_fin,"images/".$new_images); 
    imagedestroy($images_orig); 
    imagedestroy($images_fin); 
} else { 
    imagejpeg($images,"images/".$new_images); 
}

테스트 파일 크기 :

$maxSize = 50 * 1024; 

$sess=66666; 
$images = $_FILES["photoimg"]["tmp_name"]; 

if(filesize($images) > $maxSize){ 

    $sess=66666; 
    $images = $_FILES["photoimg"]["tmp_name"]; 
    $new_images = "$sess.gif"; 
    $width=200; 
    //*** Fix Width & Heigh (Autu caculate) ***// 
    $size=GetimageSize($images); 
    $height=round($width*$size[1]/$size[0]); 
    if($size[2] == 1) { 
     $images_orig = imagecreatefromgif($images); 
    } else if($size[2] == 2) { 
     $images_orig = imagecreatefromjpeg($images); 
    }else if($size[2] == 3) { 
     $images_orig = imagecreatefrompng($images); 
    } 
    $photoX = ImagesX($images_orig); 
    $photoY = ImagesY($images_orig); 
    $images_fin = ImageCreateTrueColor($width, $height); 
    ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY); 
    Imagejpeg($images_fin,"images/".$new_images); 
    ImageDestroy($images_orig); 
    ImageDestroy($images_fin); 

}
