Will PHP code come out after echo for ajax?

Question

I am launching a typical ajax webpage with php-engined. I use echo to return an html string from php code. My question is, if I have another code after the echo, will this code be executed? Or does echo behave similarly to exit, which immediately returns and stops php code execution? Thanks.

Answer 1

No, echo does not exit in any way, you usually have more than one echo in a script. exit takes a string argument that will be output before exiting, so you can do:

 exit("your string here"); 

and it will output a line and exit

Answer 2

No, there will be no echo. To get out of the echo, you could say

echo "Dear, goodbye!"; Exit();

Answer 3

echo will just return the text to the javascript part of ajax; however, the code after or before echo / echos executes

Answer 4

Not. PHP scripts are fully displayed unless you explicitly exit them. Any output to the script will be passed back to the ajax function if it was called via ajax.

 echo 'This gets outputted<br />'; echo 'As does this'; 

Answer 5

If you have to use one file and you want your script to exit after executing an ajax request without having to add additional vars to the ajax url or evaluate the vars to exit, I would suggest creating a function that executes your ajax, the function returns true if success, then do:

 if(ajaxFunction($paramOne, $paramTwo)){exit();}
