PHP - Not to execute specific code on specific page

I have one common page: default.php

<?php 

  ________Some Codes________

?>

And my project has 100+ .php files. (Yes all files have require_once 'default.php'; on the first line of all pages)

Now, I am deciding to display alert in all the files except 2. (say 1.php & 2.php).

Of course, I'll add that alert in my default.php.

So now my default.php will look like:

<?php

________Some Codes_______


echo $comn_alert = "<script>alert('Hi');</script>";

?>

Question:

How can I stop $comn_alert from executing on 1.php & 2.php?

Define a constant before including the file and then check if that constant is defined in default.php.It would be something like below:

1.php:

<?php

define('AVOID_ALERT_1',1);

require_once('default.php');

2.php:

<?php

define('AVOID_ALERT_2',1);

require_once('default.php');

default.php:

<?php 

// __some__codes

if(!(defined('AVOID_ALERT_1') || defined('AVOID_ALERT_2'))){
   echo $comn_alert = "<script>alert('Hi');</script>";
}

Several approaches:

  • You could use $_SERVER['PHP_SELF'] in default.php to check if it's included from either 1.php or 2.php
  • You could restructure your inclusion structure a little bit: Extract the common logic of default.php (i.e. the logic used in all files) into another file (e.g default_minimal.php) and make default.php require that file and contain the code in question (e.g. the alert()). Make then 1.php and 2.php only require default_minimal.php
  • Set a variable in 1.php and 2.php before requiring and then check in default.php for the existence / absence of this variable.
