Double Quotes within PHP Script Echo

When echoing HTML code within a PHP script, it's essential to handle double quotes correctly. Consider the following example:

$('#edit_errors').html('
Please Correct Errors Before Proceeding
')";
?>

This code aims to display an error message in red. However, adding the following line:

echo "";

Results in "red" being displayed in black and a compiler error. Using single quotes around "red" makes the text disappear.

To resolve this issue, you must escape the double quotes within the string using . Here's the corrected code:

$('#edit_errors').html('
Please Correct Errors Before Proceeding
')";
?>

By escaping the double quotes, PHP will interpret them as part of the string rather than end of string characters. Additionally, you can escape other characters, such as single quotes (').
