How can mysql_real_escape_string() be used to escape only specific instances of single quotes in a MySQL query in PHP?

To escape only specific instances of single quotes in a MySQL query in PHP, you can use a combination of string manipulation functions and `mysql_real_escape_string()`. First, identify the specific instances of single quotes that need to be escaped, then use `mysql_real_escape_string()` to escape those instances before constructing the query. 

// Sample query with specific instances of single quotes that need to be escaped
$query = "INSERT INTO table_name (column1, column2) VALUES ('John', 'O''Connor')";

// Escape only the specific single quote in the value 'O'Connor'
$escaped_value = str_replace("O'Connor", mysql_real_escape_string("O'Connor"), $query);

// Execute the modified query
$result = mysql_query($escaped_value);
