Question

linux下php调用C动态库，程序运行出错，求解答！！！急！！

错误提示如下：
[root@localhost hello]# php hello.php

Warning: dl(): Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20090626/hello.so' - /usr/lib/php/extensions/no-debug-non-zts-20090626/hello.so: cannot open shared object file: No such file or directory in /root/pccp/php-5.3.14/ext/hello/hello.php on line 5
Functions available in the test extension:

Warning: Invalid argument supplied for foreach() in /root/pccp/php-5.3.14/ext/hello/hello.php on line 10

Module hello is not compiled into PHP

为什么不能连接到动态库呢？　都配置了，但是不起作用
hello.php文件内容

<?php
$br = (php_sapi_name() == "cli")? "":"<br>";

if(!extension_loaded('hello')) {
dl('hello.' . PHP_SHLIB_SUFFIX);
}
$module = 'hello';
$functions = get_extension_funcs($module);
echo "Functions available in the test extension:$br\n";
foreach($functions as $func) {
echo $func."$br\n";
}
echo "$br\n";
$function = 'confirm_' . $module . '_compiled';
if (extension_loaded($module)) {
$str = $function($module);
} else {
$str = "Module $module is not compiled into PHP";
}
echo "$str\n";
?>

看起来是没找到动态链接库的文件哦,看看你的路径对不对?看看i的php.ini里面扩展的目录
