Parameters: This function accepts two parameter as mantioned above and described below: $data: It is mandatory parameter which contains the encoded string.

The base64_decode() is an inbuilt function in PHP which is used to Decodes data which is encoded in MIME base64. Base64 encoding will divide the binary data up to six-bit chunks and map them to a base64 character according to the table above. Which makes up a total of three bytes (24 bits). How does base64 work? Base64 encoding converts every three bytes of data (three bytes is 3*8=24 bits) into four base64 characters. The Base64 term originates from a specific MIME-content transfer encoding. What is Base64 in Morse code?Д«ase64 is a generic term for a number of similar encoding schemes that encode binary data by treating it numerically and translating it into a base-64 representation. This is because hex bytes are not aligned with base64 'digits'. BUT, multiple base64 encoded strings may represent a single binary/hex value. The short answer is yes, unique binary/hex values will always encode to a unique base64 encoded string. I used the php function ctype_print to check for non printable characters. if the result is same as previous string, then check if the decoded string contains printable characters. if the result is not same as the original string, then original string is not base64 encoded. Is base64 encoded PHP?Д«ase64 encode the result of previous step. Load the URL data to decode from a file, then press the ' Decode' button: Browse: Alternatively, type or paste in the text you want to URLвЂ“ decode, then press the ' Decode' button. Wikipedia has a good expalanation of how some characters should be represented in URLs and URIs. Only these characters are used by the encryption: вЂњAвЂќ to вЂњZвЂќ, вЂњaвЂќ to вЂњzвЂќ, вЂњ0вЂќ to вЂњ9вЂќ, вЂњ+вЂќ and вЂњ/вЂќ The end of a string can be padded up to two times using the вЂњ=вЂќ-character (this character is allowed in the end only) How do I decode a URL? The length of a Base64- encoded string is always a multiple of 4. Base64 is also called as Privacy enhanced Electronic mail (PEM) and is primarily used in email encryption process. What is Base64 encrypted?Д«ase64 encoding converts the binary data into text format, which is passed through communication channel where a user can handle text safely. Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML. Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation.

How can i find what my text encoding is
