What are common errors that can lead to a "Parse error: parse error, unexpected T_ECHO" message in PHP code?

A common error that can lead to a "Parse error: parse error, unexpected T_ECHO" message in PHP code is when there is a syntax error such as missing a semicolon at the end of a line, mismatched parentheses, or using reserved keywords incorrectly. To solve this issue, carefully review the code for any syntax errors and ensure that all parentheses, brackets, and semicolons are correctly placed.

// Incorrect code that may lead to a parse error
echo "Hello, World"
```

```php
// Corrected code with a semicolon added at the end of the line
echo "Hello, World";
