Guys I think it has something related to SSL!
On the test code I provided you if you change https://www.sitepor500.com.br to any domain that DOES NOT
have SSL it will work. Try changing https://www.sitepor500.com.br to any domain that does not
force https redirection and the bug goes away.
So it clearly only happen when the destination domain uses SSL.
note: this bug does not happen when using
file_get_contents.

Description:
------------
Hi,
I have found a very serious and easy to reproduce bug happening with CURL on latest PHP 7.2.X (which
is 7.2.24).
Just run the code below on your server running PHP+APACHE+MARIADB:
<?php
$curl = curl_init();
$opts = array();
$opts[CURLOPT_URL] = "https://www.sitepor500.com.br";
curl_setopt_array($curl,$opts);
echo curl_exec($curl);
?>
It will work just fine, I mean, you will see the contents of the page on CURLOPT_URL. Now JUST ADD
one single line of code to it and the bug will happen:
<?php
$conn = mysqli_connect("localhost","root","your_password");
$curl = curl_init();
$opts = array();
$opts[CURLOPT_URL] = "https://www.sitepor500.com.br";
curl_setopt_array($curl,$opts);
echo curl_exec($curl);
?>
Incredibly, just adding a connection to a local database will make CURL fetch the content of the URL
specified at CURLOPT_URL as "" (empty string). This happens with any URL.
Test script:
---------------
<?php
$conn = mysqli_connect("localhost","root","your_password");
$curl = curl_init();
$opts = array();
$opts[CURLOPT_URL] = "https://www.sitepor500.com.br";
curl_setopt_array($curl,$opts);
echo curl_exec($curl);
?>
Expected result:
----------------
You should see the URL content
Actual result:
--------------
Nothing is shown
