string to numeric.. is it possible

graziano

I have a string like this

$texta="81.30";

I wish to convert it to numeric so that I can apply a mathematic function ,
is it possible ?

I tried
$texta= float($texta);

but I receive this error
Fatal error: Call to undefined function: float()

Any help please ?
Thank you!

graziano

ok found
settype($texta, "float");

graziano

no it's doesn't work too ... argh ...

mrhappiness

$texta = (float)$texta;

graziano

it gives me this error

Fatal error: Call to undefined function: float()

mrhappiness

Not my code!

graziano

I don't know if it could be the reason however the value of $texta arrives from array like this
$text[1] .

Using settype to float I receive the value of 1 ...

either you try my code which will never ever give an error "called to undefined function" as it doesn't call any function at all or you show some more code

Did you note the difference between

$texta = float($texta);

and

$texta = (float)$texta;

It might not seem significant to you, but it makes all the difference in the world to PHP.
