将每个元素的链接添加到包含png文件的数组（php）

Question

我有一个包含不同图像文件的数组，它们只包含图像文件名。我想在该数组中的每个文件名之前添加一个url。 例如：

主阵列

    $imgUrls = array(
       'ptSignature' => '5668695879dc84.35037895.png',
       'pSignature' => '5668694f80aa55.79055562.png',
       'witness1Signature' => '5668695875c6e5.03917128.png',
       'witness2Signature' => '5668695879dc84.35037895.png',
    );

我希望他们这样：

$imgUrls = array(
       'ptSignature' => 'http://website-link.com/?page=gf_signature&signature=5668695879dc84.35037895.png',
       'pSignature' => 'http://website-link.com/?page=gf_signature&signature=5668694f80aa55.79055562.png',
       'witness1Signature' => 'http://website-link.com/?page=gf_signature&signature=5668695875c6e5.03917128.png',
       'witness2Signature' => 'http://website-link.com/?page=gf_signature&signature=5668695879dc84.35037895.png',
    );

我如何管理？

Answer 1

$imgUrls = array(
       'ptSignature' => '5668695879dc84.35037895.png',
       'pSignature' => '5668694f80aa55.79055562.png',
       'witness1Signature' => '5668695875c6e5.03917128.png',
       'witness2Signature' => '5668695879dc84.35037895.png',
    );

$imgUrls = array_map(function($el) {
    return 'http://website-link.com/?page=gf_signature&signature=' . $el;
}, $imgUrls);

var_dump($imgUrls);

您可以使用：

  foreach($imgUrls as $key=>$value) 
     { $imgUrls[$key] = 'http://website-link.com/?page=gf_signature&signature=' . $value; }
