Replace comma with OR conditional (PHP) - php

Question

I have an option for the users to write which pages they don't want to see.
Simplifying, is a text input where they will write the pages names, such "contact", "bio" etc.
While they tip "contact, bio" I have to create a conditional to hide these pages, so the content would be displayed like this on the code:
if (('contact') || ('bio')) {
hide content
}
Typing just one page would be easy but with more pages, I don't know how to replace the comma to the OR conditional. How can I do it?

Answer 1

Try to use below code:
$skip_pages = explode(",","contact, bio");
$current_page = "contact";
if(in_array($current_page,$skip_pages)){
//redirect page to ....
}
//continue with page

Answer 2

You should first take user's input in one variable
Lets say you got it in $string
$string = "contact,bio,home";
$token = strtok($string, ",");
$i=0; // To know how manny keywords are there.
while ($token != false)
{
echo "$token<br>";
$user_ip[i++] = strtok(",");
}
and then you need to parse all pages name by , and store it in array.
lets say you stored it in $user_ip
Then you need to compare it like
if ( ($user_ip[0] === "contact") || ($user_ip[0] === "bio") {
}
and check above if for all members of $user_ip.
