openssl_error_stringReturn openSSL error message


string openssl_error_string ( void )

openssl_error_string() returns the last error from the openSSL library. Error messages are queued, so this function should be called multiple times to collect all of the information. The last error will be the most recent one.

Пример #1 openssl_error_string() example

// lets assume you just called an openssl function that failed
while ($msg openssl_error_string())
$msg "<br />\n";


Note that there may be two (or more) lines for one error.

Best to clear it out and read it for each openssl call.

There are no "threads" and if the other library doesn't have enough sense to read (and therefore clear) the queue (errr, dequeue) of messages before and after their openssl calls...
A) That's their problem
B) Look for a new library, because NOT doing that means they aren't writing their code properly.

You need to do something like this to clear it:

while(openssl_error_string() !== false);

Some openssl functions will add errors to the list even if they succeed.
