I'm doing form comparison using sha1 as follows
sha1($_POST['txtEmpresa'] + $_POST['txtFornecedor'] + $_POST['txtDocumento'] + $_POST['txtValor'] + $_POST['txtVencimento']);
Is there any way to reduce this code to look like this?
sha1($_POST);
or another form of encryption that meets this need? I already used md5 and it did not work either.
You can use the implode() function , but be careful about the variable $_POST can contain parameters that you do not want and that would lead to an error.
Example:
sha1(implode('', $_POST));
One possibility is you will serialize the contents of $ _POST:
sha1(serialize($_POST));
And since you are comparing the value of two forms, it may be worthwhile to use a ksort ($ _ POST) before generating sha1 to ensure that the order of fields is the same as this you can change the value of the hash.
