How to insert my MySQL Case When Statement into PHP using PDO so I can add the output to my column chart - pdo

Question

I am working on a Column Chart and want to add the values of my MySQL Case When Statement into the chart. However, I need help to write the statement in PHP using PDO so I can integrate it into my application's column chart.How can I write the Case When Statement into PHP using PDO?
SELECT
COUNT(CASE WHEN tbl_projects.projsector = 'Agriculture' THEN 1 END) AS `AG`,
COUNT(CASE WHEN tbl_projects.projsector = 'Building Construction' THEN 1 END) AS `BC`,
COUNT(CASE WHEN tbl_projects.projsector = 'Health' THEN 1 END) AS `HT`,
COUNT(CASE WHEN tbl_projects.projsector = 'Education' THEN 1 END) AS `ED`,
COUNT(CASE WHEN tbl_projects.projsector = 'Water Supply' THEN 1 END) AS `WS`,
COUNT(CASE WHEN tbl_projects.projsector = 'Income Generation' THEN 1 END) AS `IG`,
COUNT(tbl_projects.projsector) AS 'Total SEctors',
concat(round(COUNT(CASE WHEN tbl_projects.projsector = 'Agriculture' THEN 1 END)/COUNT(tbl_projects.projsector) * 100 )) AS '% AG',
concat(round(COUNT(CASE WHEN tbl_projects.projsector = 'Building Construction' THEN 1 END)/COUNT(tbl_projects.projsector) * 100)) AS '% BC',
concat(round(COUNT(CASE WHEN tbl_projects.projsector = 'Health' THEN 1 END)/COUNT(tbl_projects.projsector) * 100)) AS '% HT', concat(round(COUNT(CASE WHEN tbl_projects.projsector = 'Education' THEN 1 END)/COUNT(tbl_projects.projsector) * 100 )) AS '% ED',
concat(round(COUNT(CASE WHEN tbl_projects.projsector = 'Water Supply' THEN 1 END)/COUNT(tbl_projects.projsector) * 100)) AS '% WS',
concat(round(COUNT(CASE WHEN tbl_projects.projsector = 'Income Generation' THEN 1 END)/COUNT(tbl_projects.projsector) * 100)) AS '% IG'
FROM tbl_projects
My expected result is supposed to look like this
AG BC HT ED WS IG TotalSEctors %AG %BC %HT %ED %WS %IG
2 1 0 2 3 0 8 25 13 0 25 38 0
Thank you in advance

Thanks to everyone who attempted to provide help to my question. I finally got solution to my question. I am going to post the code I used below.
Now there are 2 aspect of values that I needed for my chart. The first are Normal COUNT values as seen below from AG to IG and the second are Percentage values as seen from %AG to %IG.
AG BC HT ED WS IG TotalSEctors %AG %BC %HT %ED %WS %IG
2 1 0 2 3 0 8 25 13 0 25 38 0
To generate this values from the table, I digged online and found some codes on how to COUNT values in MySQL using PDO Prepared Statement. After studying the codes, I was able to write mine as seen below
<?php
//database connection
include('Connections/db.php');
//create a function for count
function rowCount($connect,$query){
$stmt = $connect->prepare($query);
$stmt->execute();
return $stmt->rowCount();
}
?>
With this line of codes, I was able to count records and then generate the percentage.
<h1> Agriculture = `<?php echo (rowCount($connect,"SELECT projsector AS '% AG' FROM
tbl_projects WHERE projsector = 'Agriculture' ") / rowCount($connect,"SELECT
projsector FROM tbl_projects ")) * 100; ?>` </h1>
<h1> Building Construction = `<?php echo (rowCount($connect,"SELECT projsector AS '%
AG' FROM tbl_projects WHERE projsector = 'Building Construction' ") /
rowCount($connect,"SELECT projsector FROM tbl_projects ")) * 100; ?> </h1>
<h1> Health = `<?php echo (rowCount($connect,"SELECT projsector AS '% AG' FROM
tbl_projects WHERE projsector = 'Health' ") / rowCount($connect,"SELECT projsector
FROM tbl_projects ")) * 100; ?>` </h1>
<h1> Education = `<?php echo (rowCount($connect,"SELECT projsector AS '% AG' FROM
tbl_projects WHERE projsector = 'Education' ") / rowCount($connect,"SELECT
projsector FROM tbl_projects ")) * 100; ?>` </h1>
<h1> Water Supply = `<?php echo (rowCount($connect,"SELECT projsector AS '% AG' FROM
tbl_projects WHERE projsector = 'Water Supply' ") / rowCount($connect,"SELECT
projsector FROM tbl_projects ")) * 100; ?>` </h1>
<h1> Income Generation = `<?php echo (rowCount($connect,"SELECT projsector AS '% AG'
FROM tbl_projects WHERE projsector = 'Income Generation' ") /
rowCount($connect,"SELECT projsector FROM tbl_projects ")) * 100; ?>` </h1>
OUTPUT
Agriculture = 25%
Building Construction = 12.5%
Health = 0%
Education = 25%
Water Supply = 37.5%
Income Generation = 0%
For Normal COUNT Values with no percentage, I use these codes
Agriculture = <?php echo rowCount($connect,"SELECT projsector AS '% AG' FROM
tbl_projects WHERE projsector = 'Agriculture' "); ?>
Building Construction = <?php echo rowCount($connect,"SELECT projsector AS '% BC'
FROM tbl_projects WHERE projsector = 'Building Construction' "); ?>
Health = <?php echo rowCount($connect,"SELECT projsector AS '% HT' FROM tbl_projects
WHERE projsector = 'Health' "); ?>
Education = <?php echo rowCount($connect,"SELECT projsector AS '% ED' FROM
tbl_projects WHERE projsector = 'Education' "); ?>
Water Supply = <?php echo rowCount($connect,"SELECT projsector AS '% WS' FROM
tbl_projects WHERE projsector = 'Water Supply' "); ?>
Income Generation = <?php echo rowCount($connect,"SELECT projsector AS '% IG' FROM
tbl_projects WHERE projsector = 'Income Generation' "); ?>
I trust someone will find these useful
