Explode data in PHP using custom condition

Question

Can anyone please help me? I have a data in a column called column_hide the data is 0,1

I want to explode and put a condition if attribute data-column same with value in column_hide I added down class and here is my error screenshot

<div class="pull-right">
<button style="font-size:7pt" class="toggle-vis <?= ($value==0 ? "" : "") ?>" data-column="0">PARTS NO</button>
<button style="font-size:7pt" class="toggle-vis" data-column="1">REVISED NO</button>
<button style="font-size:7pt" class="toggle-vis" data-column="2">LATEST NO</button>
<button style="font-size:7pt" class="toggle-vis" data-column="3">DESCRIPTION</button>
<button style="font-size:7pt" class="toggle-vis" data-column="4">IN FIFO</button>
<button style="font-size:7pt" class="toggle-vis" data-column="8">TOTAL QTY</button>
<button style="font-size:7pt" class="toggle-vis" data-column="9">STOCK J</button>
<button style="font-size:7pt" class="toggle-vis" data-column="10">STOCK B</button>
<button style="font-size:7pt" class="toggle-vis" data-column="11">STOCK S</button>
<button style="font-size:7pt" class="toggle-vis" data-column="12">STOCK X</button>
<button style="font-size:7pt" class="toggle-vis" data-column="13">STORAGE</button>
<button style="font-size:7pt" class="toggle-vis" data-column="14">LAST OPNAME</button>
<button style="font-size:7pt" class="toggle-vis" data-column="15">DISCONTINUED</button>
<button style="font-size:7pt" class="toggle-vis" data-column="16">MESIN</button>
<button style="font-size:7pt" class="toggle-vis" data-column="17">SRP PRICE</button>
<button style="font-size:7pt" class="toggle-vis" data-column="18">SRP COD</button>
<button style="font-size:7pt" class="toggle-vis" data-column="20">MANAGER</button>
<button style="font-size:7pt" class="toggle-vis" data-column="21">DIRECTOR</button>
<button style="font-size:7pt" class="toggle-vis" data-column="22">NOTE</button>

right but each has its own value, so 0 OR 1 right? what does the table structure look like? does it contain the name e.g. STOCK X and the column id e.g. 12 and the column hide as well? — Alex

@Alex no, it can be filled 0,1,2,3 till 22 and if the value same with data-column attribut i want add class downs — Not a Pwntester

strange schema. you should have made this all 1 table with columns column_name (varchar 50), column_id (int), and hidden (bool). then you could generate this all with a simple foreach. that is what i suggest doing. storing multi purpose string data/serialized data is never a good idea — Alex

Two ways of doing it. Example:

<?php

$string = '0,1,3';

$array = explode(',', $string);

// METHOD 1
// better performance

$flip = array_flip($array); // only have to do this once

if (isset($flip[3])) {
    echo 'true';
}

// OR

// METHOD 2
// probably less efficient

if (in_array(3, $array)) {
    echo 'true';
}

Of course the if logic has to be repeated per "column". The number, in this example 3, will have to be hard coded per each button.

Still suggest making a table like I said in the comments.
