restore_include_path

Function name: restore_include_path()

Function Description: This function is used to restore the value of include_path that was modified using the set_include_path() function.

Function usage: The restore_include_path() function does not accept any parameters.

Sample code:

 // 设置新的include_path set_include_path('/path/to/directory'); // 备份当前的include_path $backup = get_include_path(); // 修改include_path set_include_path('/another/path'); // 恢复之前的include_path restore_include_path(); // 输出恢复后的include_path echo get_include_path(); // 输出/path/to/directory

In the example above, we first set a new include_path using the set_include_path() function. Then, we backed up the current include_path value using the get_include_path() function. Next, we use the set_include_path() function to modify include_path. Finally, we use the restore_include_path() function to restore include_path to the previous backup value. The last line of code uses the get_include_path() function to output the restored include_path value to verify whether the recovery is successful.

Note that the restore_include_path() function only restores the include_path value modified by the set_include_path() function, and does not restore the other way of modifying the include_path.
