In this post, we will discuss How to Passing An Array To A Query Using A WHERE Clause using a ‘where’ clause along with the ‘in’ operator for the same we have given an example here.
Passing An Array
The Syntax for the same is given below here.
SELECT * FROM table _name WHERE column_ name IN ('value1', 'value2', 'value3');
Here in the above-given example, the table name is the name of the table you want to query, the column name is the name of the column you want to filter by, and ‘value1’, ‘value2’, and ‘value3’ are the values in the array that you want to filter for.
for using this query in an array for PHP, we can create the string that contains the comma separated list of values in the array, and then concatenate the string into the query. So for the same, we have given an example for the same we were already given the syntax before.
$values = array('value1', 'value2', 'value3');
$value_list = "'" . implode("', '", $values). "'";
$query = "SELECT * FROM table_ name WHERE column_name IN ($value_list)";
In this example, $value is the array of values you want to filter for,$value list is a string that contains the values in the array separated by commas and enclosed in single quotes, and $Query is the MySQL query that includes the $value list string in the in clause.
And there is another way to do the same is by using it we can use “where” clause to use prepared statements. As the prepared statement is nothing but a way to execute a SQL statement repeatedly which has high efficiency.
The example of the same here we have given here to execute.
// Create a prepared statement
$stmt = $mysqli->prepare("SELECT * FROM table_name WHERE column_name IN (?".str_repeat(",?", count($values)-1).")");
// Bind the values in the array to the prepared statement
$stmt->bind_param(str_repeat("s", count($values)), ...$values);
// Execute the prepared statement
$stmt->execute();
// Get the result set
$result = $stmt->get_result();
// Loop through the result set and do something with the data
while ($row = $result->fetch_assoc()) {
// do something with $row
}
// Close the prepared statement and the database connection
$stmt->close();
$mysqli->close();
In this example, $mySQL is a MySQLi object representing the database connection, $value is the array of values you want to filter for, and the Column name is the name of the column we want to filter by.
