AddSlashes to a String Online

Form to mimic PHP's addslashes()

AddSlashes is a PHP function named after the addslashes() function. It adds backslashes before special characters in a string. This online tool provides the same functionality as PHP's addslashes() function, making it perfect for preparing strings for database storage or other contexts where special characters need to be escaped. The function escapes:

• Single quotes (')
• Double quotes (")
• Backslashes (\)
• NULL bytes (\0)

Note: The NULL bytes (\0) don't work in this tool, as it's not a valid character to input.

Common use cases for escaping

String escaping is essential in many scenarios:

• Preparing strings for MySQL queries
• Creating safe database entries
• Handling user input in PHP applications
• Preventing SQL injection attacks
• Creating safe string literals

This tool is particularly useful when you need to quickly escape strings for database operations or when working with legacy code that requires addslashes() functionality.

It's also helpful for learning and understanding how string escaping works in PHP.

Some best practices

When working with string escaping:

• Always escape user input before database storage
• Use appropriate escaping for your database type
• Consider using prepared statements for SQL
• Test with various special characters
• Validate input before escaping

While addslashes() is a fundamental PHP function, modern applications often use more sophisticated methods like prepared statements or ORM systems. However, understanding addslashes() is still important for maintaining legacy code and understanding PHP's string handling capabilities.
