How can PHP automatically add a backslash before quotation marks in an array?

When working with arrays in PHP that contain strings with quotation marks, it is important to escape the quotation marks with a backslash to prevent syntax errors. One way to automatically add a backslash before quotation marks in an array is to use the array_map() function along with a custom function that escapes the quotation marks. 

// Define a custom function to escape quotation marks
function escapeQuotes($str) {
    return str_replace('"', '\"', $str);
}

// Define an array with strings containing quotation marks
$array = ['Hello, "World"', 'PHP is "awesome"'];

// Use array_map() to apply the escapeQuotes function to each element in the array
$escapedArray = array_map('escapeQuotes', $array);

// Output the escaped array
print_r($escapedArray);
