我想获取产品的SKU，
请帮我为此编写正则表达式。
这是我的代码 -
$url = "http://api.findify.io/v1.0/store/search?callback=jQuery111206735094679573879_1458022087824&q=154701001&key=5b31ee91-78fa-48e1-9338-1748ca55028e&analytics%5Bkey%5D=5b31ee91-78fa-48e1-9338-1748ca55028e&analytics%5Bvisit%5D=true&analytics%5Buniq%5D=true&analytics%5Burl%5D=http%253A%252F%252Fwww.pandorasoem.com%252Fsearch%2523q%253D154637401&analytics%5Bbaseurl%5D=http%253A%252F%252Fwww.pandorasoem.com%252Fsearch%2523q%253D154637401&analytics%5Bhost%5D=www.pandorasoem.com&analytics%5Bwidth%5D=1920&analytics%5Bheight%5D=1200&analytics%5Binner_width%5D=1438&analytics%5Binner_height%5D=667&analytics%5Bdoc_width%5D=1438&analytics%5Bdoc_height%5D=915&analytics%5Bscroll_x%5D=0&analytics%5Bscroll_y%5D=0&analytics%5Bvisit_id%5D=Ts22zuHHGJRZc3U1&analytics%5Buniq_id%5D=BoeCUKSzgdML6C50&byPage=24&page=0&_=1458022087825";
$ch1= curl_init();
curl_setopt ($ch1, CURLOPT_URL, $url );
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch1,CURLOPT_VERBOSE,1);
curl_setopt($ch1, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0)');
curl_setopt ($ch1, CURLOPT_REFERER,'http://www.google.com'); //just a fake referer
curl_setopt($ch1, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch1,CURLOPT_POST,0);
//curl_setopt($ch1, CURLOPT_FOLLOWLOCATION, 20);
$htmlContent= curl_exec($ch1);
curl_close($ch1);
preg_match_all('/["'']?totalHits["'']?'s*:'s*('d+)/i', $htmlContent, $count);
print_r($count);
preg_match_all('/"sku".*:.*"(.*)".*/i', $htmlContent, $sku);
print_r($sku);
它在获取 SKU 时显示空白数组。它适用于Totalhits。
更新网址
只需从 URL 中删除回调参数，它就会返回正确的 JSON，然后您可以将 JSON 转换为数组或对象并执行任何您想要的操作
从网址中移除callback=jQuery111206735094679573879_1458022087824&
要将 JSON 转换为数组，请使用 json_decode （ http://php.net/manual/en/function.json-decode.php ）
所以在你得到$htmlContent之后，你可以用$jsonData = json_decode($htmlContent,true);转换它
您可以print_r JSON 来检查其键/值，
或者如果你想得到sku列表 -s
$skus = Array();
foreach($jsonData['data']['hits'] as $hit) {
$skus[] = $hit['sku'];
}
