What potential issue might arise from using a long echo statement in PHP code?

Using a long echo statement in PHP code can make the code less readable and harder to maintain. To solve this issue, it's recommended to break the long echo statement into multiple lines using concatenation (.) or using heredoc syntax for multi-line output. 

// Long echo statement
echo "This is a long sentence that spans multiple lines and can make the code harder to read.";

// Fix using concatenation
echo "This is a long sentence that spans" . 
    "multiple lines and can make the code" . 
    "harder to read.";

// Fix using heredoc syntax
echo <<<EOT
This is a long sentence that spans
multiple lines and can make the code
harder to read.
EOT;
