How can the presence of backslashes in serialized data affect the unserialize() function in PHP?

When serialized data contains backslashes, it can cause issues when using the unserialize() function in PHP because backslashes are used as escape characters. To solve this issue, you can use the stripslashes() function to remove the backslashes before passing the serialized data to unserialize(). 

$serializedData = 'a:2:{s:4:"name";s:6:"John";s:3:"age";s:2:"25";}';
$unserializedData = unserialize(stripslashes($serializedData));

print_r($unserializedData);
