Laravel google images search - php

Question

In my application users creating articles and adding images to it if user wont add a image, that application must search for it in google images. I'm googling it quite long but still can't find which tools do I need to achieve this.
EDIT
I tried Mimos approach but now something going wrong and now I get:
NotReadableException in AbstractDecoder.php line 302:
Image source not readable
When i tried to save the image from url
ArticlesController store method:
public function store(ArticleRequest $request)
{
if ($request->hasFile('file')) {
$file = Input::file('file');
$imgTitle = $request->title;
$imagePath = 'uploads/' . $imgTitle . '.jpg';
$request->image_path = $imagePath;
Article::create(array('title' => $request->title,
'body' => $request->body,
'image_path' => $imagePath));
Image::make($file)->resize(300, 200)->save($imagePath);
} else {
// $file = Input::file('file');
$imgTitle = $request->title;
$query = $imgTitle;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=" . urlencode($query));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = json_decode(curl_exec($ch));
// $file = file_get_contents($output);
curl_close($ch);
$imagePath = 'uploads/' . $imgTitle . '.jpg';
$request->image_path = $imagePath;
Article::create(array('title' => $request->title,
'body' => $request->body,
'image_path' => $imagePath));
Image::make($output)->resize(300, 200)->save($imagePath);
}
}

Answer 1

<?php
$query = 'Foobar';
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=".urlencode($query));
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string as json
$output = json_deocde(curl_exec($ch));
// close curl resource to free up system resources
curl_close($ch);
But I don't recommend to let a program decide what image it should take. You will maybe get a problem with copyright. Better set a default pic.
