How can PHP developers avoid syntax errors when using single quotes and double quotes in echo statements?

PHP developers can avoid syntax errors when using single quotes and double quotes in echo statements by properly escaping the quotes that are used within the string. This can be done by using the backslash (\) character before the quote that needs to be escaped. Alternatively, developers can also use a combination of single and double quotes to avoid conflicts.

// Using backslash to escape quotes
echo 'I\'m using single quotes with an escaped single quote inside.';
echo "He said, \"I'm using double quotes with escaped double quotes inside.\"";

// Using a combination of single and double quotes
echo 'He said, "I\'m using a mix of single and double quotes."';
echo "She said, 'I\'m doing the same with double and single quotes.'";
