 The Decoded data is an Array of Objects of PHPZxing\ZxingImage if the bar code is found. If not found then it is an array of Objects PHPZxing\ZxingBarNotFound.
 
+Checking for existence of Barcode

+The Existance of bar code can be found using the functoin isFound()

+```php
+use PHPZxing\PHPZxingDecoder;

+You can also check using the instanceof object,
+```php
+use PHPZxing\PHPZxingDecoder;

 Set Java Path
 ----------
 If your java PATH is not set properly, the decoder will not work. You need to set path of java variable.
