Php - 检查包含或代码块是否有错误

How would I go about checking if and include or a require has an error in it. For example, and include would try to be included, if that page has an error the page isn't included and a message is throw?

Cheers.

You can't catch a parse error in PHP in the same language environment (for obvious reasons).

One approach might be to run php -l your_included_file.php using exec and then check the exit code. The -l (lint) argument checks that your code can be parsed correctly.

You can't trap parser errors.

However, if the code executes something that causes an exception to be thrown, you could catch it with a try/catch block.

You can try using file_exist function, it check whether the file exist or not.

$filename = "/path/to/file.php";
if(file_exists($filename)){
   include $filename;
}else{
   include "errorpage.php";
}
