how to solve this real problem

mster

As you know my PHP application is made of several modules(codes). I need a global variable (array) to be set up at the first module and then be visible and accessible from all the others. I am getting confused on where to put the variable, and where to declare it global to clarifying:
1. I have an array of variables in the first code 1.php
2. the first code 1.php is recall the 2.php
1.php
Include (“2.php”)
3.the array it works fine up to this stage.
4. the second code 2.php is recall the 3.php by sending data.
5. the third code 3.php is recall the 2.php by including 2.php..the array work so far.
6. steps number 4, 5 will repeating for many times.
.so because the array has works at first time but it would not works again for repeating time. I know the problem is: in repeating time the array will be empty. Could you please help me to solve this problem.

If I'm understanding your issue, then the $_SESSION array exists to solve this problem.

<?php
//1.php

session_start();

$_SESSION['foo']="some text here";

echo "<a href=\"2.php\">Click me!</a>";

?>

<?php
//2.php

session_start();
echo $_SESSION['foo'];
   // prints "some text here"

?>
