Parse error: syntax error, unexpected 'const' (T_CONST), expecting variable (T_VARIABLE) in Laravel project

Title: Understanding and Resolving "Parse error: syntax error, unexpected 'const'..." Errors in Laravel Projects Introduction The Parse error: syntax error, unexpected 'const' (T_CONST), expecting variable (T_VARIABLE) you encounter might be due to a variety of reasons. This blog post aims to explore these reasons and shed light on how to fix them effectively in your Laravel project. Keep reading to gain insights into the root causes and possible solutions for this error. Reason 1: PHP Version Compatibility As illustrated in the given example, the local server's PHP version is 7.2.0 while Bluehost uses PHP 7.0.0.

The conflict with the syntax (const) could be a result of this version disparity. To resolve this issue, use the latest PHP version on both your local machine and Bluehost. By keeping up-to-date, you can avoid such errors in future updates.
