Using the Sql ALTER TABLE statement, it is possible to delete the column in the MySQL table using PHP.

syntax:
ALTER TABLE `table_name` DROP `column_name`;

Example:


<?php
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "basename";
$conn = mysqli_connect($dbhost, $dbuser, $dbpass , $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "ALTER TABLE membership
DROP `lastname`, DROP `date`";
if (mysqli_query($conn, $sql)) {
echo "Column deleted successfully";
} else {
echo "Deleting a column failed" . mysqli_error($conn);
}
mysqli_close($conn);
 ?>


It is also possible to delete multiple columns in the MySQL table.

syntax:
ALTER TABLE "table_name" DROP "column_name1", DROP "column_name2";

Example:


<?php
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "basename";
$conn = mysqli_connect($dbhost, $dbuser, $dbpass , $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "ALTER TABLE membership
DROP `date`";
if (mysqli_query($conn, $sql)) {
echo "Column deleted successfully";
} else {
echo "Deleting a column failed" . mysqli_error($conn);
}
mysqli_close($conn);
 ?>
