What are the potential issues with removing spaces from extracted data before inserting it into a MySQL database?

Removing spaces from extracted data before inserting it into a MySQL database can lead to data integrity issues, as spaces may be meaningful in certain fields (such as names or addresses). To solve this issue, it is recommended to trim the data to remove leading and trailing spaces without altering the content of the data.

// Assuming $extractedData contains the extracted data
$cleanedData = array_map('trim', $extractedData);

// Insert cleaned data into MySQL database
// Example query: INSERT INTO table_name (column1, column2) VALUES ('$cleanedData[0]', '$cleanedData[1]');
