php imap functions with cronjob

I have a php script with imap functions. All is fine when I call the php file from browser, but when it run with cronjob the following error:

    X-Powered-By: PHP/5.3.27
    Set-Cookie: bgm=31dc5ff02b6a3d1614a9dd1c39321fd0; path=/

    <br />
    <b>Warning</b>:  imap_open() [<a href='function.imap-open'>function.imap-open</a>]: Couldn't open stream {"hostname":993/imap/notls/ssl} in <b>/"path"/cron.php</b> on line <b>173</b><br /> 
    <br/><br/><span style='color:red'></span><pre>Certificate failure for "hostname": unable to get local issuer certificate: /C=US/O=GeoTrust Inc./CN=GeoTrust Global CA</pre><br/><br/><br />

OS: CentOS 5.9 The cronjob was created with Cpanel: /usr/bin/php file.php. The imap_last_error() give the following error: Certificate failure for "hostname": unable to get local issuer certificate: But when i call the cron.php from any browser that certificate failure doesn't come and all works fine.

OpenSSL takes the CA bundle file location / CA directory location either as a parameter (command line or library method call) or from the environment variables SSL_CERT_FILE / SSL_CERT_DIR.

My guess is in this case the Apache environment had one of these set correctly and the cron environment did not. Two solutions:

  1. set one of these env variables at the top of the crontab:

SSL_CERT_FILE="/path/to/ca-bundle.crt"

  1. set the env variable in the php script before opening imap connection:

putenv('SSL_CERT_FILE=/usr/share/ssl/certs/ca-bundle.crt');

Thank you to @Daniel-Roethlisberger for inspiring me to find this second solution based on his solution in Ruby: https://stackoverflow.com/a/14797635/2294879

I think also it must be possible to specify a default bundle location in the build of the imap program/library that PHP uses (because my imap connection used to work fine before applying the above), but this is surely more hassle.

It seems as if PHP is unable to verify the certificate. Can you check whether it works when adding /novalidate-cert to the resource URL?
