MD5 was proposed by Ronald Rivest in 1991 Ask a new question Source codeĭCode retains ownership of the "MD5" source code. Indeed, in this case, the PHP engine will convert the string into a floating number having the value 0.īonus strings that can also be evaluated at 0: 0e215962017, 0e730083352, 0e807097110, 0e840922711
However this functionality can become a flaw when handling MD5 string whose value has the form 0e followed by digits between 0 and 9. The PHP language has a default functionality: the type juggling which allows to not define the type of variable used, the PHP engine tries to automatically detect if the variable is a string, an integer, etc.
