On one server I've got php-5.6.7-1 and I installed ioncube there without a hitch. I put ioncube_loader_lin_5.6.so into /usr/lib/php5/20131226, and added zend_extension = ioncube_loader_lin_5.6.so to php.ini.

But that doesn't work for the other server. I've got php-5.4.4-14+deb7u4 there. I put ioncube_loader_lin_5.4.so into /usr/lib/php5/20100525, and added zend_extension = ioncube_loader_lin_5.4.so to php.ini.

$ php -i | grep extension_dir
extension_dir => /usr/lib/php5/20100525 => /usr/lib/php5/20100525
$ php --version

On the first server php apparently loads the library without any problem:

$ strace php --version
...
futex(0x7fbf391860c8, FUTEX_WAKE_PRIVATE, 2147483647) = 0
open("/usr/lib/php5/20131226/ioncube_loader_lin_5.6.so", O_RDONLY|O_CLOEXEC) = 3
read(3, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\220o\2\0\0\0\0\0"..., 832) = 832
...

Has it something to do with some configure options, that are preventing it from searching for zend extensions inside /usr/lib/php5/20100525? Is there a way to find them out? What am I to do?

Try to specify the full path:

zend_extension = /full/path/to/ioncube_loader_lin_5.4.so

I don't know from when is this change, but one was used to always specify full path for zend_extension until a build of PHP 5.5 (on Fedora, but I think it's the same on Debian). I think it's a maintainer choice.

  • It seems as of php-5.5.0 one can specify path to zend extensions relative to extension_dir directory. – x-yuri May 6 '15 at 23:17
  • @x-yuri thank you for the information. I've read the changelogs but was unable to find such a feature. So thank you for your follow-up, I understand now. – apaul May 7 '15 at 6:19
