"break sequence"

[Anon]

I need something like a "supervising control structure" that watches one variable, like this pseudo-code:

break on ($x>0) {
$x = myfunc(something);
some_other_command(s);
$x = otherfunc(otherparm);
$x = myfunc(otherparm);
...
}

so $x just collects the return code of some functions that set other (global) vars - but I have to leave that calling function, if one of the called indicates an error. I can't tell the called function "break here, and leave the called function, too", unfortunately...

Is there anything like this in php3, or does somebody have a solution?

Not that exact structure, but you can set something up like it if the track_errors directive is on:

$cmds = array (
"myfunc(something);",
"some_other_command(s);",
"otherfunc(otherparm);"
);

for ($i = 0; $i < count ($cmds); $i++)
{
eval ("@$cmds[$i]");
if ($php_errormsg)
break;
}

if ($php_errormsg)
echo "Error occurred: $php_errormsg\n";

Alternatively you could reinstitute the $x variable in each command then check it so you wouldn't have to rely on $php_errormsg:

$cmds = array (
"\$x = myfunc(something);",
"some_other_command(s);",
"\$x = otherfunc(otherparm);"
);

for ($x = 0, $i = 0; $i < count ($cmds); $i++)
{
eval ($cmds[$i]);
if ($x)
break;
}

if ($x)
echo "Error occurred: $x\n";

Thank you, Eden!

it's not exactly what I was thinking about - but so very similiar to it, that it matches my needs! Second variant is most suitable 😉
