在保持客户端在同一页面上的同时运行第二个PHP脚本

Question

I'm creating a app that requires me to run a second php script while the first script is still running.

I'm new to php programing so I'm sure there's a simple function I can use that I'm just not aware of.

Looking forward to any help...

Answer 1

Since you are new to PHP I'm guessing you're looking for the include / require (and include_once / require_once ) language constructs which will execute another PHP script as if it is part of the current script.

Otherwise if you want it to run as a separate process look into exec , shell_exec , or backticks . If you need the other PHP script to run as a background process make sure to redirect stdout somewhere (a file or maybe /dev/null if you don't need it) so that your currently executing script doesn't have to wait for it to finish to continue executing.

This will actually require us to use some Javascript for an ajax call to execute our PHP and return it's data.

I prefer Jquery, which will look similar to this:

function callPHP(){           
     $.post('./filetocall.php', {variableid: 'id'}, function (response) {
                        $("#div_for_return_data").val(response);
                });
}

filetocall.php can look like anything. It's output will populate the #div_for_return_data

eg:

<?php echo $_GET['variableid']; ?>

Then just call the Jquery function from anywhere.
