Include, Require a syntax error file

Question

I would like to ask can I require/include a file that has syntax errors and if I cant, the require/include returns a value so that I know that the required/included file has syntax errors and cannot be required/included ?

file.php has syntax error

include('file.php')
if (not file.php included because of syntax)
   this
else
   that

Answer 1

If you really wanted this type of functionality.

You could try using nikics php parser to see if you can successfully parse the file or not.

$code = file_get_contents('yourFile.php');

$parser = new PhpParser\Parser(new PhpParser\Lexer\Emulative);

try {
    $stmts = $parser->parse($code);
    // $stmts is an array of statement nodes
    // file can be successfully included!
} catch (PhpParser\Error $e) {
    // cannot parse file!
    echo 'Parse Error: ', $e->getMessage();
}

Answer 2

you can use something ike this:

if((@include $filename) === false)
{
    // handle error
} else { //....}

the @ is used to hide the error message

Answer 3

In PHP 7, Parsing errors can be caught, which makes this probably the most robust, elegant, built-in solution:

<?php

function safe_require_once(string $fname) {
    try {
        require_once($fname);
    } catch( Throwable $e ) {
        //will throw a warning, continuing execution...
        trigger_error("safe_require_once() error '$e'", E_USER_WARNING);
    }
}

safe_require_once("./test1.php"); //file with parse or runtime errors
echo "COMPLETED SUCCESSFULLY THO";
