How can the "Parse error: parse error, unexpected T_STRING" error be resolved in PHP?

The "Parse error: parse error, unexpected T_STRING" error in PHP typically occurs when there is a syntax error in the code, such as a missing semicolon or quotation mark. To resolve this error, carefully review the code for any syntax mistakes and correct them accordingly.

// Incorrect code causing parse error
echo "Hello, world"
```

```php
// Corrected code without syntax error
echo "Hello, world";
