在 php 中编写一个函数
I'm using the following code
我正在使用以下代码
echo 'Curl: ', function_exists('curl_version') ? 'Enabled' : 'Disabled';
this can get it enabled or disabled
这可以启用或禁用它
but I would like to make as function say function name is _iscurl
但我想作为函数说函数名称是 _iscurl
then I can call it as following any where in my website code
然后我可以在我的网站代码中的任何位置调用它
if (_iscurl()){
echo "this is enabled"; // will do an action
}else{
echo "this is disabled"; // will do another action
}
almost same as my previous question check if allow_url_fopen is enabled or not
与我之前的问题几乎相同，检查是否启用了allow_url_fopen

return false;

// Ouput text to user based on test
if (_is_curl_installed()) {
echo "cURL is <span style=\"color:blue\">installed</span> on this server";

You can always create a new page and use phpinfo(). Scroll down to the curl section and see if it is enabled.
您始终可以创建一个新页面并使用phpinfo(). 向下滚动到 curl 部分，看看它是否已启用。

Its always better to go for a generic reusable function in your project which returns whether the extension loaded. You can use the following function to check -
在您的项目中使用通用的可重用函数总是更好，该函数返回是否加载了扩展。您可以使用以下功能来检查 -
function isExtensionLoaded($extension_name){
return extension_loaded($extension_name);
}
Usage
用法
echo isExtensionLoaded('curl');
echo isExtensionLoaded('gd');
