Why is it recommended to escape ' in strings using \' in PHP?

When using single quotes in a string in PHP, it is recommended to escape the single quote with a backslash (\') to prevent syntax errors. This is necessary because PHP interprets the single quote as the end of the string, causing issues if the single quote is part of the string content. By escaping the single quote, PHP will recognize it as a literal character within the string. 

// Example of escaping single quote in a string

echo $string;
