Hi,

What are you trying to do this code seems like it isn't suppose to do anything besides give errors. It makes no sense.
First of all what is blah it is not a variable since it doesn't have $ in front of it. And what is this break suppose to do. I've only seen the break command in a switch statement or loop.
here is an example when to use the break command:

Code:

   switch ($i) {
   case 5:
       echo "At 5<br />\n";
       break 1;  /* Exit only the switch. */
   case 10:
       echo "At 10; quitting<br />\n";
       break 2;  /* Exit the switch and the while. */
   default:
       break;
   }

What are you trying to achieve?

hi,

thanks for replying DJ Kat, you guessed it right 'blah' is NOT a variable it is a 'static' variable.....i know 'break', without a static label is only used in breaking out of nested 'if' loops or as u mentioned in the case of switch.....
What i was trying to do was to find an equivalent of GOTO statement used in C, in php5.......but too my pity the link that i have given above mentions minutes of a meeting of the group of php developers..so the break with a static label may be present in newer versions of php,,, but till now its not there in php5......

i however found a patch developed by someone to get a GOTO running in php....but i dont know how to use it>>>here's the link >>>>>> http://pecl.org/patches/opcode_goto_5.1.0.diff.....see if you can help me .......

Hi,

I've seen goto in old basic and flash but I wonder, why would you need the GOTO statement? There different ways to approach your problem i think the GOTO statement has become obsolete in modern programming languages.

I am very confident that what ever you want to build you won't need the GOTO thing.
