Question

Is there a way in PHP to try to include a file, but if the file contains errors that stop it from compiling to just skip that file from inclusion?

Answer 1

You can call php -l on the file in question. This will shell out and slow though.
it doesn’t handle runtime errors like die() though.

test.php:

<?php
function check_code_file($filename)
{
    $filename = escapeshellcmd($filename);
    system("php -l $filename 2>/dev/null 1>/dev/null", $status);
    if ($status) return false;
    return true;
}
if (check_code_file('test-good.php'))
{
    include('test-good.php');
}
if (check_code_file('test-bad.php'))
{
    include('test-bad.php');
}
print "finished\n";

test-good.php:

<?php
print "here\n";

test-bad.php:

<?php
die(

$ php test.php

here
finished
