我相信这对你有好处.任何帮助将不胜感激.
我想将一个数组传递给包含参数的PHP函数,所有参数都是可选的.我正在使用代码点火器,绝不是专家.以下是我到目前为止使用的内容：
function addLinkPost($postDetailArray) {
if (isset($postDetailArray['title'])) {
$title = $postDetailArray['title']; }
else {
$title = "Error: No Title";
}
if (isset($postDetailArray['url'])) {
$url = $postDetailArray['url'];
} else {
$url = "no url";
}
if (isset($postDetailArray['caption'])) {
$caption = $postDetailArray['caption'];
} else {
$caption = "";
}
if (isset($postDetailArray['publish'])) {
$publish = $postDetailArray['publish'];
} else {
$publish = TRUE;
}
if (isset($postDetailArray['postdate'])) {
$postdate = $postDetailArray['postdate'];
} else {
$postdate = "Now()";
}
if (isset($postDetailArray['tagString'])) {
$tagString = $postDetailArray['tagString'];
} else {
$tagString = "";
}
你可以这样做：
function addLinkPost(array $postDetailArray)
{
$fields = array(
'key' => 'default value','title' => 'Error: No Title',);
foreach ($fields as $key => $default) {
$$key = isset($postDetailArray[$key]) ? $postDetailArray[$key] : $default;
}
}
只需使用您的密钥及其默认值编辑$fields数组.
