Unsigned int to signed in php. Ask Question Asked 10 years, 6 months ago. ... PHP does not support unsigned integers as a type, but what you can do is simply turn the result of ip2long into an unsigned int string by having sprintf interpret the value as unsigned with %u:
https://www.php.net/manual/en/language.types.integer.php
The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). 64-bit platforms usually have a maximum value of about 9E18, except on Windows prior to PHP 7, where it was always 32 bit. PHP does not support unsigned integer s. Integer size can be determined using the constant PHP_INT_SIZE, maximum value using the constant ...

Note that PHP on Windows does not support 64-bit integers at all, even if both the hardware and PHP are 64-bit. See this link for details: On windows x86_64, PHP_INT_MAX is 2147483647. This is because in the underlying c-code, a long is 32 bit. However, linux on x86_64 uses a 64bit long so PHP_INT_MAX is going to be 9223372036854775807.

Freely switching between int and float is good for most cases, but problems happen when your value is near the word size of your machine. Which is to say, 32-bit machines will encounter problems with values that hover around 0x80000000 - primarily because PHP does not support unsigned integers.

PHP does not support unsigned integers. Integer size can be determined from PHP_INT_SIZE, maximum value from PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5." This is particularly important if you are doing validation of large keys or any number larger than 2,000,000,000 (e.g. telephone numbers)

Nov 13, 2008 · Schema API supports unsigned integers, but Database API does not allow inserting/updating unsigned integers. I think it's because there's %u placeholder. Any chance to get this fixed for D6? Please note that one could workaround this building the SQL statement by hand, but this is not an option when using a CCK field that implements an unsigned integer because CCK uses …

PHP does not support unsigned integers. Warning If an invalid digit is passed to octal integer (i.e. 8 or 9), the rest of the number is ignored. Example 11-2. Octal weirdness <?php var_dump(01090); // 010 octal = 8 decimal ?> Integer overflow If you specify a ...

However, PHP just brought me a new definition of “portable” – and that was when working with… integers. PHP is not able to handle unsigned integers, and converts values over 2^31 to signed. So if your IDs go slightly over 2 billion, and PHP decides to treat them as integers, you’re in trouble.
