How can using double quotation marks in PHP echo statements affect the output in different browsers?

Using double quotation marks in PHP echo statements can cause issues in output if the string being echoed contains HTML attributes or special characters that need to be enclosed in double quotation marks. This can lead to syntax errors or unexpected behavior in different browsers. To solve this issue, you can escape the double quotation marks inside the string using a backslash (\) before each double quotation mark.

<?php
// Using escape character to handle double quotation marks
echo "<a href=\"#\">Click here</a>";
?>
