Class Checksum.
The Checksum class provides utility methods for calculating
MD5 checksums for both strings and files. This class is
designed to facilitate the verification of data integrity by
allowing users to generate checksums that can be used to
identify changes or ensure the consistency of file contents.
It encapsulates the functionality to compute checksums in a
straightforward manner, making it easy to use in various
applications dealing with file storage and data management.
fromContent(string $content) : string
Calculates the MD5 checksum of the provided content.
This method takes a string as input and computes its MD5 checksum. The resulting checksum can be used to verify data integrity or detect changes in the content.
| string | $content | The content for which to calculate the checksum. |
The MD5 checksum of the given content.
fromFile(string $filename) : string
Calculates the MD5 checksum of the specified file.
This method reads the specified file and computes its MD5 checksum. The checksum can be used for file integrity checks to ensure that the content has not been altered since the checksum was generated.
| string | $filename | The path to the file for which to calculate the checksum. |
If the file cannot be read.
The MD5 checksum of the specified file.
