Wordpress - Display text if checkbox output matches the page title - php

Question

I want to show the projects that has had it's checkbox ticked as Branding, if it's on the Branding page (i.e the page title is Branding).
To explain the code a bit:
This line show's all the checkboxes that have been ticked for each project so it will output "Branding", "Web", "Print" if they have been ticked.
implode(', ',get_field('categories')
This next line is just checking the page title is "Branding":
implode(', ',get_field('categories')
I'm trying to put these both in an if statement where it would just output the checked boxes and if they match the title then output them.
<?php if(implode(', ',get_field('categories')) && $grid_title == "Branding"); {
echo "testing";
}
?>
The code above shows what I want to do but it doesn't quite work.
IMPORTANT: I'm using this plugin to create the custom checkboxes so please bear that in mind.
=============================
UPDATE:
Thanks very much to Adam Kiss for solving what I asked, small update to question:
How could I code this neatly - using your answer, Branding was just one example of the check boxes, there's also several other one's like Web, Print, Social so how could I match those to the page title as well?
So it will be along the lines of if checked field equals the page title "branding" do OR checked field equals page title "web" OR checked field equals page title "print".

Answer 1

the function you're looking for is in_array:
<?php
if(
in_array("Branding", get_field('categories'))
&& $grid_title == "Branding"
){
echo "testing";
}
Note: this assumes that result of that implode is array with strings like "Branding", "Web", etc.
Edit: Since we're using implode(), I assume get_field returns type array, so we put the implode away (I got confused for a while)
Edit: Sorry, was away :]
you could use array_intersect
Usage:
$categories = get_field('categories');
$cats_iwant = array("Branding", "Print", "Design");
$inarray = array_intersect($categories, $cats_iwant);
//this '$inarray' now has values like 'Branding', 'Design' which are in both arrays
if (count($inarray) > 0) {
//we have at least one common word ('Branding', ...)
}
//short version
if (count(array_intersect(get_field('categories'),array(
'Branding', 'Design', 'Print'
))) > 0)
{
//do stuff
}
