php 找不到 zend 扩展 (ioncube)

在我拥有的一台服务器上php-5.6.7-1，我ioncube顺利地安装在那里。我放入ioncube_loader_lin_5.6.so，/usr/lib/php5/20131226并添加zend_extension = ioncube_loader_lin_5.6.so到php.ini。

但这对其他服务器不起作用。我已经到php-5.4.4-14+deb7u4了。我放入ioncube_loader_lin_5.4.so，/usr/lib/php5/20100525并添加zend_extension = ioncube_loader_lin_5.4.so到php.ini。

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

现在到有趣的部分：

在第一台服务器上php显然加载库没有任何问题：

$ 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
...

configure这与某些阻止它在内部搜索 zend 扩展的选项有关吗/usr/lib/php5/20100525？有办法找到他们吗？我是什么做的？

答案1

尝试指定完整路径：

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

我不知道这个变化是从什么时候开始的，但是在 PHP 5.5 版本之前，一直使用一个变化来指定完整路径zend_extension（在 Fedora 上，但我认为在 Debian 上也是一样）。我认为这是维护者的选择。
