What are the best practices for handling quotation marks within strings in PHP?

When handling quotation marks within strings in PHP, it is important to properly escape them to prevent syntax errors. One common way to do this is by using the backslash (\) character before the quotation mark to escape it. Another approach is to use single quotes ('') to enclose the string if it contains double quotes, or vice versa. This ensures that the quotation marks are treated as literal characters within the string.

// Example of handling quotation marks within strings in PHP

// Using backslash to escape double quotes
$doubleQuotedString = "This is a \"quoted\" string";
echo $doubleQuotedString;

// Using single quotes to enclose string with double quotes
$singleQuotedString = 'This is a "quoted" string';
echo $singleQuotedString;
