diff() and date_diff() in PHP not working for some reason

I’m having a problem using PHP’s ‘diff()’ or ‘date_diff()’ between two dates of mine. Basically when I run anything that attempts to compare dates or try to define something as a date the page will stop loading at that point.

<?php

    // My starting point is the $dirty_date variable.
    // It is collected from a string, parsed, 
    // and ends up being an integer-based date / seconds past Unix Epoch

    //I am also including some echos along the way for debugging purposes.

    echo "Check 1: ".$dirty_date."<br>";

    $systemdate = date("U");
    echo "Check 2: ".$systemdate."<br>";

    //$interval =  $dirty_date->diff($systemdate);
    echo "check 3: ".$interval;

Here are the results:

Check 1: 1490781836

Check 2: 1490806703

check 3:

Check 3 returned nothing because I have the line which diffs it commented out. I have it commented out because if it is enabled, the page doesn't load anything else past that point.

First, $newdate is not defined. Second, $dirty_date must be a DateTime object currently it is just an integer. I will assume you want to compare $dirty_date and $systemdate

Try this:

$dirty_date_obj = new DateTime();
$dirty_date_obj->setTimestamp((int) $dirty_date);

$system_date_obj = new DateTime();
$system_date_obj->setTimestamp((int) $systemdate);


echo "interval between dirty and system: ".$dirty_date_obj->diff($system_date_obj)->format('%a Days and %h hours');

Also please type this in the beginning of your code to see the error messages so it isn't just a blank page if some error happens:

error_reporting(E_ALL); ini_set('display_errors', '1');

Here's an example

    $dirty_date = new \DateTime();
    $dirty_date->setTimestamp("your integer date");
    echo "Check 1: ".$dirty_date->format(\DateTime::ISO8601)."<br>";


    $systemdate = new \DateTime();
    echo "Check 2: ".$systemdate->format(\DateTime::ISO8601)."<br>";

    $interval =  $dirty_date->diff($systemdate);
    echo "check 3: ".$interval->format("%R%a days");
