> php doesn't call functions based on the parameters given
Ah hah! OK, that changes everything - I was thinking like C++ classes, which, if my
memory serves me correctly, know which member function to use.
Modified code that deals with this OK:
========================================================
#!/usr/bin/php -q
<?php
error_reporting (E_ALL);
class test {
var $currentField;
function setCurrentField($field_name) {
$this->currentField = $field_name;
}
function getValue($field_name = false) {
if ($field_name === false) $field_name = $this->currentField;
return "getValue with arg - $field_name\n";
}
}
$frm = new test;
$frm->setCurrentField("blah");
print $frm->getValue("real arg");
print $frm->getValue();
?>
========================================================
> That's an ZE problem (ie.
> method with same name should give parse error or at least some
> warning).
Agreed.
Testing this with straight functions shows that the engine does do this for straight
functions:
========================================================
#!/usr/bin/php -q
<?php
error_reporting (E_ALL);
function blah() {
print "no arg\n";
}
function blah($field) {
print "with arg, $field\n";
}
blah();
blah("test");
?>
========================================================
Output gives:
[root tmp]# ./test.php
<br>
<b>Fatal error</b>: Cannot redeclare blah() in <b>./test.php</b> on line <b>9</b><br>
[root tmp]#
An equivalent "Cannot redeclare test class member function blah() in test.php on line
9" would be extremely helpful and is probably called for - I've always found the PHP
syntax checking to extremely clear and spot-on previously.
Many thanks for all your help,
Kind Regards,
Nick.

Your code is obviously bogus.
You're definig two methods with the same name. But I admit this shouldn't be possible,
derick?
Anyway, because of this the second getValue() overwrites the former and therefore you
have an infinite look; getValue calls getValue calls getValue calls ...
That's an ZE problem (ie. method with same name should give parse error or at least
some warning).
(Correct if otherwise)
ps: php doesn't call funtions based on the parameters given

Can you try the latest RC from : www.php.net/~zeev/php-4.1.0RC3.tar.gz ?

The problem: Segmentation fault when using class that accesses member functions &
variables.
A short script that reproduces the problem:
[note, this is a command line script, but an equivalent web script doesn't work
either]
========================================================
#!/usr/bin/php -q
<?php
error_reporting (E_ALL);
class test {
var $currentField;
function setCurrentField($field_name) {
$this->currentField = $field_name;
}
function getValue($field_name) {
return "getValue with arg - $field_name\n";
}
function getValue() {
return $this->getValue($this->currentField);
}
}
$frm = new test;
$frm->setCurrentField("blah");
print $frm->getValue();
?>
========================================================
What happens:
[root tmp]# ./file.php
Segmentation fault (core dumped)
[root tmp]#
What I would expect to happen:
[root tmp]# ./file.php
getValue with arg - blah
[root tmp]#
============================================
Extra info about the setup being used:
O/S is Linux Mandrake 7.2 with the shipped Linux 2.2.17 kernel, and the installed PHP
uses updated RPMs that are available from the distribution's web site.
