获取Google字体列表

Question

I want to get list of google web fonts in select box to select a font. I am trying following function, but it gives the error.

Code:

function get_google_fonts() {
    $url = "https://www.googleapis.com/webfonts/v1/webfonts?sort=alpha";
    $result = json_response( $url );
        $font_list = array();
        foreach ( $result->items as $font ) {
            $font_list[] .= $font->family;          
        }
        return $font_list;  
}

function json_response( $url )  {
    $raw = file_get_contents( $url, 0, null, null );
    $decoded = json_decode( $raw );
    return $decoded;
}

Error:

Warning: file_get_contents(): Unable to find the wrapper "https" - did you forget to enable it when you configured PHP.

If I change the https to http, I get this error:

file_get_contents(http://www.googleapis.com/webfonts/v1/webfonts?sort=alpha): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden in

I guess this is because of PHP settings on my server, which I am unable to change. So, is there any alternative way to get the font list from Google? Thanks.

To allow https wraper you must have the php_openssl extension and enable allow_url_include

You can edit you php.ini to set these values :

extension=php_openssl.dll

allow_url_include = On

If these values doesn't exist add these lines .

If you can't edit your php.ini file, then you can set in on the PHP file :

ini_set('allow_url_fopen', 'on');
ini_set('allow_url_include', 'on');

You could also try using CURL instead of file_get_contents. CURL is much faster than file_get_contents

$url = "https://www.googleapis.com/webfonts/v1/webfonts?sort=alpha";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
curl_close($ch);

echo $result;

Hope this helps. :)
