In what scenarios would examining the source code be helpful in identifying issues related to string length discrepancies in PHP?

When dealing with string length discrepancies in PHP, examining the source code can be helpful in identifying issues such as incorrect string manipulation functions, inconsistent encoding, or unexpected character truncation. By reviewing the code, you can pinpoint where the discrepancy is occurring and make necessary adjustments to ensure consistent string length handling.

if(strlen($string) > $maxLength){
    $string = substr($string, 0, $maxLength);
}

echo $string; // Output: Hello, Wor
