How to iterate in google ocr textannotation object with php? - php

Question

I'm trying to get pages, paragraphs, blocks, etc
similar to the code below but in PHP.
https://cloud.google.com/vision/docs/fulltext-annotations
"""Returns document bounds given an image."""
client = vision.ImageAnnotatorClient()
bounds = []
with io.open(image_file, 'rb') as image_file:
content = image_file.read()
image = types.Image(content=content)
response = client.document_text_detection(image=image)
document = response.full_text_annotation
# Collect specified feature bounds by enumerating all document features
for page in document.pages:
for block in page.blocks:
for paragraph in block.paragraphs:
for word in paragraph.words:
for symbol in word.symbols:
if (feature == FeatureType.SYMBOL):
bounds.append(symbol.bounding_box)
if (feature == FeatureType.WORD):
bounds.append(word.bounding_box)
if (feature == FeatureType.PARA):
bounds.append(paragraph.bounding_box)
if (feature == FeatureType.BLOCK):
bounds.append(block.bounding_box)
# The list `bounds` contains the coordinates of the bounding boxes.
I was able to create this
require AUTOLOAD;
use Google\Cloud\Vision\VisionClient;
use Google\Cloud\Vision\V1\ImageAnnotatorClient;
use Google\Cloud\Vision\V1\TextAnnotation;
$path = 'img scr';
$imageAnnotator = new ImageAnnotatorClient();
$image = file_get_contents($path);
$response = $imageAnnotator->documentTextDetection($image);
$texts = $response->getFullTextAnnotation();
But I'm facing a hard time trying to iterate with the TextAnnotation object.
Either I got the message Cannot use object of type Google\Cloud\Vision\V1\TextAnnotation as array .Even if I try to force the object as array.
Here is the documentation from google for the object

Answer 1

To get the result from $response->getFullTextAnnotation(); try the following:
$response->getFullTextAnnotation()->getText();
