Sharing variables between functions

[sharmilah]

Hi all

It's me again.. I have a variable to which i am assigning a value in one function. I have to use the variable with the same value assigned in another function. How can I do this. I've tried to portray this in the following codes

Thanks.


[PHP]Function x
{
$a =25
}

Function y
{
If ($a=25)
sql_insert();
}[/PHP]

$toFuncTwo = 25;  // CHANGE THIS
return $toFuncTwo; 
}
 
function FuncTwo($ReturnedValuefromFuncOne){
    if($ReturnedValuefromFuncOne==25)
    {
    $Msg = 'True';
    }else
    {
    $Msg = 'False';
    }
return $Msg;
}
$returnValue =FuncOne();
print FuncTwo($returnValue);
?>

you could also make a "global" variable

[PHP] $var = '';

function funcOne()
{
$var = 25;
}

function funcTwo()
{
echo $var;
}

echo $var; //outputs an empty string
funcOne();
funcTwo(); //outputs 25
[/PHP]
but i like ajaxrands solution more, since one rarely want to use global variables unless unavoidable :)
