Edit report at https://bugs.php.net/bug.php?id=78891&edit=1 ID: 78891 User updated by: gilperon at gmail dot com Reported by: gilperon at gmail dot com Summary: Bug with CURL completely stopped working Status: Duplicate Type: Bug Package: Unknown/Other Function Operating System: all PHP Version: 7.2.25 Block user comment: N Private report: N New Comment: requinix@php.net you are right. This bug now only happens when opening a mysqli connection previously to using CURL with HTTPS. I have no idea how this bug "fixed" itself cause I could easily reproduce it on a fresh install of centos + lamp on Linode (cloud server company) and I didnt any "yum update" after the install. Have no idea how it got fixed HOWEVER the bug still happens when opening a mysqli connection previsouly to using CURL with HTTPS. Previous Comments: ------------------------------------------------------------------------ [2019-12-02 02:43:26] requinix@php.net If your original code, the one where you do *not* do anything over an SSL connection before using cURL, is no longer causing any problems then we're back to this being a duplicate of the other report. ------------------------------------------------------------------------ [2019-12-02 02:30:13] gilperon at gmail dot com One more thing, I tried using the CART file from https://curl.haxx.se/ca/cacert.pem and it also does show the same exactly error, so I am pretty cure there is no problem with cacert or certificate bundle. ------------------------------------------------------------------------ [2019-12-01 14:17:20] gilperon at gmail dot com nikic@php.net I just woke up right now and went to try your code and suddenly this bug went away. I didnt make ANY update yesterday. I didnt do "yum update" and for some reason CURL came back to work! Then I tried adding the line of code - mysqli_connect("localhost","root","password") - above the CURL and then it crashed again. Which means that the bug that I reported a few days back came back to happen again. So now, CURL only does not work when opening the mysqli connection. Nikik I tried that 2 line of codes you asked me and the output follows below: CODE: <?php $conn = mysqli_connect("localhost","root","password"); $curl = curl_init(); $opts = array(); $opts[CURLOPT_URL] = "https://www.sitepor500.com.br"; $opts[CURLOPT_RETURNTRANSFER] = true; curl_setopt_array($curl,$opts); var_dump(curl_exec($curl)); var_dump(curl_errno($curl)) ?> OUTPUT bool(false) int(77) I investigated, and 77 means -> CURLE_SSL_CACERT_BADFILE. ALSO one even strange thing, if I replace $conn = mysqli_connect("localhost","root","password"); with just mysqli_connect("localhost","root","password"); The bug goes away and everything works! Hope this helps and if you want me to execute any other code, I am here to help! ------------------------------------------------------------------------ [2019-12-01 12:25:32] nikic@php.net It's pretty weird that curl_error() doesn't report anything here. Just to double check, if you replace the "echo curl_exec($curl)" with "var_dump(curl_exec($curl))", do you get "bool(false)" or "string(0)"? And afterwards, does "var_dump(curl_errno($curl))" give "int(0)" as well? ------------------------------------------------------------------------ [2019-11-30 17:14:40] gilperon at gmail dot com One more note: using "echo curl_error($curl); " shows a blank string! So curl is not showing any error. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
