In order to get image content , use the following 要获取图像内容，请使用以下内容
$data = '<meta itemprop="name" content="Saurabh Sharma"><meta itemprop="description" content="Works at Google as Product Manager. Lives in San Francisco. Lived in New Delhi - Mumbai - Canonsburg - Pittsburgh - Austin - San Francisco."><meta itemprop="image" content="//lh5.googleusercontent.com/-0qGW989h9DM/AAAAAAAAAAI/AAAAAAAAG3g/aXkL8mbboKY/photo.jpg"><meta itemprop="url" content="https://plus.google.com/+SaurabhSharma"></head><body class="Td lj"><input type="text" name="hist_state" id="hist_state" style="display:none;">'; $ data = '<meta itemprop="name" content="Saurabh Sharma"><meta itemprop="description" content="Works at Google as Product Manager. Lives in San Francisco. Lived in New Delhi - Mumbai - Canonsburg - Pittsburgh - Austin - San Francisco."><meta itemprop="image" content="//lh5.googleusercontent.com/-0qGW989h9DM/AAAAAAAAAAI/AAAAAAAAG3g/aXkL8mbboKY/photo.jpg"><meta itemprop="url" content="https://plus.google.com/+SaurabhSharma"></head><body class="Td lj"><input type="text" name="hist_state" id="hist_state" style="display:none;">';
preg_match('/<meta itemprop=\"image\" content=\"(.*?)\">/i', $data, $matches);
$matches will return an array $ matches将返回一个数组
Array
(
