php echo adding on "0');" to the end of the output

Question

I run a local server I am working on and php echo appears to be freaking out. This is the error:

echo "<script>console.log('test');</script>";

yields

<script>console.log('test');</script>;0')</script>

when I "view page source" of the webpage. In the page itself, this shows up as just 0'); and the console.log() appears to be working just fine. If I change one of these to remove all javascript and just do something like

echo "testing";

what shows up is:

testing0');</script>

when I write a new echo it works fine, when I have tried making new pages, they also work fine, when I view it in safari (I regularly use chrome) this problem persists. This problem occurs each time I echo a script, but when echoing something else it behaves normally. Only if I change an existing echo to plain text does it still append the ;0')</script>, when I write a new echo that writes a script it works just fine.

If I add die(); after any echo statements, that one (and that one only) lacks the ;0')</script> all those above it still have it at the end.

What the heck did I do to cause this?

info: I am using the default apache install on mac and php version 5.5.36. Feel free to ask me clarifying questions and if need be I can post the full php file on github.

Thanks in advance,

Lewis

Edited for clarity.

What if you type `echo "testing"; die();`? It seems like you have an extra `echo` farther down. — WOUNDEDStevenJones, Jul 24 '17 at 22:19
You are either `echo`ing `0')` father down, or you have `0')` outside of PHP tags father down the page. Show more code please. — StackSlave, Jul 24 '17 at 22:30
I guess I should have been more clear, this happens on multiple lines wherever I have `echo "";` — Lewis Smith, Jul 24 '17 at 22:40

Well I feel pretty dumb, I was indeed spitting out ;0')</script> after each and every echo, because all of my console.log()s came in pairs and the second one always looked something like this:

echo "\n<script type=\"text/javascript\">\n    console.debug('".'  '+gettype($sql_peices)."');\n</script>";

and the plus in there was causing the issue, I should have:

echo "\n<script type=\"text/javascript\">\n    console.debug('".'  '.gettype($sql_peices)."');\n</script>";

with a period. I have no idea when or how I put that in there, but now everything is working perfectly.

sure, no problem. should I just include it in the question? – Lewis Smith Jul 25 '17 at 22:43
Maybe just update the first code block to include it. – Shadow Jul 26 '17 at 01:08
