bug or just my own incompetence?

[areisinger]

Hi all,
consider this content of test.php (PHP 5.2.1 installation on a
powweb.com server)

<?php
function logit (string $message)
{
echo "i´m here ";
}
mysql_query("foobar"); // ignore error message
logit(mysql_error());
?>

Ignoring the forced failure of mysql_query the following call to logit
brings this error message:

Catchable fatal error: Argument 1 passed to logit() must be an
instance of string, string given, called in ....... test.php

mysql_error should return string, logit requires string, where is the
real problem hidden?

best regards
a

There is no string class in PHP, so mysql_error() returns a string ( a
chain of characters ), and the logit function requires an object which
is an instance of a "string" class. And it's absolutely not exists
there.

Try this.

<?php
function logit ($message)

Thank you very much, i found the "hint" in the docs after your answer:
