What are some common errors that may occur when trying to implement a new code snippet in PHP?

One common error that may occur when implementing a new code snippet in PHP is syntax errors, such as missing semicolons or parentheses. Another issue could be using undefined variables or functions within the snippet. To solve these errors, carefully review the code for any syntax mistakes and ensure all variables and functions are properly defined.

// Incorrect code snippet with syntax errors and undefined variables
$variable = 10
echo "The value of the variable is: $variable";

// Corrected code snippet with proper syntax and defined variables
$variable = 10;
echo "The value of the variable is: $variable";
