Unserialize() takes a single serialized variable and converts it back into a PHP value. Warning Do not pass untrusted user input to unserialize() regardless of the options value of allowed_classes. Serialize a object including it's function into a JSON. Serialize a object including it's function into a JSON. ![]() I've been working on some very large forms lately and I've come to the conclusion that creating a database scheme around them wouldn't be the best option because: • My customers don't need to analyze all form submissions as a whole -- form information is simply used on a per-submission basis (like a job application, for example). • Making updates to these forms would be very costly since it would take quite a bit of time to add and remove DB fields as well as update the HTML form. • I'd like to revert the information into an array format just like it came in easily. For that reason, I've been using the serialize() and unserialize() functions often. Serializing an array keeps the information in an array format, so to speak, but in one long string. Anyways, I ran into the following error when testing unserialize on some information that I had serialized: Notice: unserialize(): Error at offset 2 of 52 bytes in file.php on line 130 It turns out that if there's a ', ',:, or; in any of the array values the serialization gets corrupted. I've found the following fix for this issue on: //to safely serialize $safe_string_to_store = base64_encode(serialize($multidimensional_array)); //to unserialize. $array_restored_from_db = unserialize(base64_decode($encoded_serialized_string)); It's a great fix to simple problem! You need to escape a serialized string in a manner appropriate for your DB, just as you do for any string. For example, mysql_real_escape_string() or prepared statements in the case of MySQL. If you base64_encode() the serialized string then you will probably obviate escaping regardless of database it since the base64 code table uses only ASCII’s alpha, numeric, + and / characters. But that doesn’t mean it’s a good solution. I think base64_encode() not a good replacement for using your DB’s correct escape procedures for efficiency reasons. Design experts gain from a full option in which printer, connectivity components, inks, and media have been created with each other to create the best outcomes. It has actually been produced for layout specialists who need a budget-friendly solution in regards to high image quality and also the simplicity of use to create remarkable large-format shade result. The HP Designjet 455ca printer has the brand-new HP Designjet 455ca SPLIT (Raster Picture Processing) software, consisting of a degree 2 PostScript (R) interpreter which equates PostScript data for the outcome to HP RTL. Hp designjet 500 plotter driver. The HP Designjet 455ca large-format printer is based on the HP Designjet 400 series platform. Sometimes code fragments found on the web will work as drop-in but are a poor substitute for understanding. I agree with Shimon in this, there is no reason why adding that layer of base64 encoding AFTER the serialization occurs, should resolve a problem with the unserialization, unless, and that’s not been specified in here, the serialized data was messed up by some escaping function, encoding conversion, etc, before or after being stored in a database or similar. I understand that in that case, preventing the data from containing characters suscettible to escaping such as quotes, would be of help, but it’s not a general case. Excellent solution. This is definitely a good way to go. I was thinking of using the preg_replace function to replace any single quotes, double quotes, semi_colons, or colons with a set of characters that is unlikely to be used in the string. For instance: $variable = preg_replace(‘| ’|’, “_SINGLEQUOTE_”, $variable); $variable = preg_replace(‘| ’|’, “_DOUBLEQUOTE_”, $variable); $variable = preg_replace(‘| ’|’, “_SEMICOLON_”, $variable); $variable = preg_replace(‘| ’|’, “_COLON_”, $variable); $variable = serialize($variable); The downside to this solution is that it is a lot of work for a similar result and the unserialize function must utilize the same code but in reverse. I haven’t yet tested the two but speed can definitely be a factor in which direction you would want to go. Also, with the preg_replace solution, you must use a string that will NOT be used in the variable at all or strange results will occur. Again, thanks for sharing your solution. Supported OS: Windows 10, Windows 8/8.1, Windows 7, Windows Vista. Epson fx 2175 driver for windows 8.1 32 bit. Node Js Php Serialize And UnserializersI believe it may be a way that I will go with my code and its certainly a clever use of the base64_encode()/decode() functions. Thank you for you help! Although your solution wasn’t quite enough to get it to work for me it was definitely part of the solution. Node Js Php Serialize And UnserializerI was trying to store the serialized string to my sql server db in a text field. After I realized that the ” were causing problems with unserialize and used the base64_encode I then realized that the string was being truncated when retrieving it from the db.
