How to check if allow_url_fopen is enabled or not

Question

I'm using the following code

echo 'file_get_contents : ', ini_get('allow_url_fopen') ? 'Enabled' : 'Disabled';

this can get it enabled or disabled

but I would like to make as function say function name is _isgetcontents

then I can call it as following any where in my website code

if (_isgetcontents()){
  echo "this is enabled"; // will do an action
}else{
  echo "this is disabled"; // will do another action
}

Use ini_get() (docs) to get the value of certain configuration parameters:

if( \filter_var( \ini_get('allow_url_fopen'), \FILTER_VALIDATE_BOOLEAN ) ) {
   // lucky me...
}

That `if()` is not reliable, as `ini_get()` returns a string of the configuration option, i.e., it could return the string `'Off'` and the conditional would consider it `true`. This should be the right check: `if ( filter_var( ini_get( 'allow_url_fopen' ), FILTER_VALIDATE_BOOLEAN ) )` – Pablo S G Pacheco Nov 17 '22 at 16:38

That's valid point. I edited my answer to include your filter for those who do not read but do copy&paste coding. Thanks. – Marcin Orlowski Nov 17 '22 at 18:06
Sure, thanks for changing it. Sometimes I do that myself :) – Pablo S G Pacheco Nov 17 '22 at 21:13

you can also use this method

phpinfo()

to check various configurations.

This does not answer the question as you can't use `phpinfo()` in an `if` statement. – Cœur Jul 14 '18 at 17:43
@Cœur Thanks for correcting me.:) – Faiyaz Alam Jul 16 '18 at 08:41
In my phpinfo() there isn't this setting! – Life after Guest Nov 16 '21 at 07:56
