I am trying to convert my base64 image string to an image file. This is my Base64 string:
Using following code to convert it into an image file:
function base64_to_jpeg( $base64_string, $output_file ) {
$ifp = fopen( $output_file, "wb" );
fwrite( $ifp, base64_decode( $base64_string) );
fclose( $ifp );
return( $output_file );
}
$image = base64_to_jpeg( $my_base64_string, 'tmp.jpg' );
But I am getting an error of invalid image
, whats wrong here?
An easy way I'm using:
file_put_contents($output_file, file_get_contents($base64_string));
This works well because file_get_contents
can read data from a URI, including a data:// URI.
That's an old thread, but in case you want to upload the image having same extension-
$image = $request->image;
$imageInfo = explode(";base64,", $image);
$imgExt = str_replace('data:image/', '', $imageInfo[0]);
$image = str_replace(' ', '+', $imageInfo[1]);
$imageName = "post-".time().".".$imgExt;
Storage::disk('public_feeds')->put($imageName, base64_decode($image));
You can create 'public_feeds' in laravel's filesystem.php-
'public_feeds' => [
'driver' => 'local',
'root' => public_path() . '/uploads/feeds',
],
This code worked for me.

if($_SERVER['REQUEST_METHOD']=='POST'){
$image_no="5";//or Anything You Need
$image = $_POST['image'];
$path = "uploads/".$image_no.".png";
$status = file_put_contents($path,base64_decode($image));
if($status){
echo "Successfully Uploaded";
}else{
echo "Upload failed";
}
}
$datetime = date("Y-m-d h:i:s");
$timestamp = strtotime($datetime);
$image = $_POST['image'];
$imgdata = base64_decode($image);
$f = finfo_open();
$mime_type = finfo_buffer($f, $imgdata, FILEINFO_MIME_TYPE);
$temp=explode('/',$mime_type);
$path = "uploads/$timestamp.$temp[1]";
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded->>> $timestamp.$temp[1]";
This will be enough for image processing. Special thanks to Mr. Dev Karan Sharma
maybe like this
function save_base64_image($base64_image_string, $output_file_without_extension, $path_with_end_slash="" ) {
//usage: if( substr( $img_src, 0, 5 ) === "data:" ) { $filename=save_base64_image($base64_image_string, $output_file_without_extentnion, getcwd() . "/application/assets/pins/$user_id/"); }
//
//data is like: data:image/png;base64,asdfasdfasdf
$splited = explode(',', substr( $base64_image_string , 5 ) , 2);
$mime=$splited[0];
$data=$splited[1];
$mime_split_without_base64=explode(';', $mime,2);
$mime_split=explode('/', $mime_split_without_base64[0],2);
if(count($mime_split)==2)
{
$extension=$mime_split[1];
if($extension=='jpeg')$extension='jpg';
//if($extension=='javascript')$extension='js';
//if($extension=='text')$extension='txt';
$output_file_with_extension=$output_file_without_extension.'.'.$extension;
}
file_put_contents( $path_with_end_slash . $output_file_with_extension, base64_decode($data) );
return $output_file_with_extension;
}
You need to remove the part that says data:image/png;base64,
at the beginning of the image data. The actual base64 data comes after that.
Just strip everything up to and including base64,
(before calling base64_decode()
on the data) and you'll be fine.
