Deprecation of mysql_* Functions in PHP 5.5.0 and Beyond
In the transition from PHP 5.2.0 and earlier to PHP 5.5.0, you may encounter difficulties with deprecated mysql_* functions. The mysql_real_escape_string() function, deprecated in PHP 5.5.0, has been replaced by mysqli_real_escape_string() in the mysqli extension.
Error and Resolution:
You are receiving the error "Deprecated: mysql_real_escape_string(). To resolve this, replace the function call with mysqli_real_escape_string($connection, $escapestring)." The mysqli_real_escape_string() function requires two arguments: $connection and $escapestring.
Modified Code Snippet:
<code class="php"><?php $username = mysqli_real_escape_string($connection, stripslashes($_POST['username'])); $password = mysqli_real_escape_string($connection, stripslashes($_POST['password'])); ?></code>
Here, $connection represents the established connection to the MySQL database.
Additional Notes:
- Consider using a database object to simplify connection handling.
- Refresh your PHP knowledge to stay up-to-date with deprecated and updated functions.
- For further information, refer to the official PHP documentation on mysqli_real_escape_string().
The above is the detailed content of What is the replacement for the deprecated mysql_real_escape_string() function in PHP 5.5.0 and beyond?. For more information, please follow other related articles on the PHP Chinese website!

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
