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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78845&edit=1
