PHP exec return openssl error

[DMG]

I want somehow from web access svn repository end get some data from it. I use XAMPP for Linux v5.6.28 (PHP 5.6.28) and tried to make svn.so, but I could not create it, because of openssl error. Now I' trying to call svn command with php exec, but still same error:

svn: relocation error: /usr/lib/x86_64-linux-gnu/libserf-1.so.1: symbol GENERAL_NAME_free, version OPENSSL_1.0.0 not defined in file libcrypto.so.1.0.0 with link time reference

PHP script I use:

Code: Select all

<?php
$output = shell_exec('svn info 2>&1');
print_r($output);
?>

If I change it to this:

Code: Select all

<?php
$output = shell_exec('openssl version 2>&1');
print_r($output);
?>

I get this error:

openssl: /opt/lampp/lib/libssl.so.1.0.0: version OPENSSL_1.0.1' not
found (required by openssl) openssl:
/opt/lampp/lib/libcrypto.so.1.0.0: versionOPENSSL_1.0.1' not found (required by openssl) openssl: /opt/lampp/lib/libcrypto.so.1.0.0: version `OPENSSL_1.0.2g' not found (required by openssl)

Everything works fine from console, but somehow not working from web. Any ideas, how to fix this in Ubuntu 16.04?
I have latest XAMPP version (5.6.28). Tested this in two Linux laptops with fresh XAMPP and Ubuntu and both has same error message.

From console, svn and everything else runs in your personal environment from your UserId (i.e. environment variables etc.). "From web" means, Apache executes the scripts (via PHP) and Apache runs in a different environment with a different UserID. You have to establish the same environment for Apache as for your UserID. You may run Apache with your own UserID (see "User = " and "Group = " in httpd.conf), but this also requires some rights/owners changes for some folders under /opt/lampp (htdocs etc.).

Even if I execute it like this:

Code: Select all

/opt/lampp/bin/php svn.php

?

And it works even if I do this:

Code: Select all

sudo -s -u www-data
/opt/lampp/bin/php svn.php

From web it does not work even if I change user and group in httpd.conf. I created new linux user, changed user and group in httpd.conf and again same old ssl error.

Finally it is working! I downloaded 5.6.20 version and everything just works. Ubuntu latest openssl version is OpenSSL 1.0.2g, so I guess ssl version must match with XAMPP ssl version or else it's not working.
