Calling java script in PHP

[Dormilich]

that depends on what’s inside myfile.php

[Dheeraj Joshi]

Ok.. Markus... Then what does this return?

`php myfile.php`

A string or ............... ..?

Actually, back-ticks, like in other languages, do run the contents as a shell command.

interesting, need to make a (mental) note of that.

[Markus]

actually… no. if you want to ‘execute’ a file you need to load/include it. and that doesn’t return a value…

// 4 different ways to include a file
include "file.php";
include_once "file.php";
require "file.php";
require_once "file.php";

and backticks are not valid string delimiters.

the only constructs able to return a value are variables, constants, functions, properties and methods (the latter 2 being special cases from to objects)

Actually, back-ticks, like in other languages, do run the contents as a shell command.

printf("PHP is located at %s", `which php`);
// equivalent of doing
printf("PHP is located at %s", shell_exec('which php'));

[Dormilich]

take it out of the switch(), currently that’s preventing the print.

[Markus]

yeah Mark..

I a gave that echo still it do not give anything.

I have either missed something obvious, or the javascript tag is completly wrong.

"<scriptlanguage=javascript> 
        alert('Blah Blah')
</script>";

Should be:

echo "<script type=\"text/javascript\">
        alert('Blah Blah')
</script>";

[Markus]

Ok.. Thanks..

Back to my java script problem?

How i have embedded the java script, is it correct?

You're missing the echo/print call in the case.

[Dormilich]

if you don’t need a condition, just echo it out.

So this basically must hold the return value of function myfun() in myfile.

let’s say that myfun() must return a value.

so the code now looks sensible.

[Dheeraj Joshi]

You mean,

include("myfile.php");

$res=myfile::myfun();

So this basically must hold the return value of function myfun() in myfile.

$res=`php myfile.php`

it executes file named myfile.php and gives the result back.

[Dheeraj Joshi]

Yeah they are backticks

$res=`php myfile.php`

it executes file named myfile.php and gives the result back.
