php-7.1

This isn't a question as it is more of a be aware. I updated an application that uses json_encode() to PHP7.1.1 and I was seeing an issue with floats being changed to sometimes extend out 17 digits. According to documentation, PHP 7.1.x started to use serialize_precision instead of precision when encoding double values. I'm guessing this caused an example value of 472.185 to become 472.18500000000006 after that value went through json_encode() . Since my discovery, I have reverted back to PHP 7.0.16 and I no longer have the issue with json_encode() . I also tried to update to PHP 7.1.2 before

Mcrypt function has been deprecated as of PHP 7.1.0. My deprecated string encode / decode functions: $key: secret key $str: string $encoded = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $str, MCRYPT_MODE_CBC, md5(md5($key)))); $decoded = rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, md5($key), base64_decode($str), MCRYPT_MODE_CBC, md5(md5($key))), "\0"); Can you suggest some alternatives? You should use openssl_encrypt instead. Regards! Consider using defuse or RNCryptor , they provide a complete solution, are being maintained and is correct. For MCRYPT_RIJNDAEL_256 I posted a
