Value Equals Anything?

[Wayniac]

Hello all,

 

Just a quick one here, I'm not sure what to put in the quotations of an if statement if I want to say if value equals ANYTHING.

 

Thanks

<?php
if ($value == "newbtophp") {
//blah blah
}
?>

I think I could reword it a little better. I'm trying to accomplish an action from an if statement that will work if anything from a space, to a letter, to a full fledge word is entered in the value spot within the "".

 

Ex:

<?php
if ($fname == "ANYTHING") { // But I can't just put ANYTHING in that slot via server side, it would have to be typed.
//blah blah
}
?>

So check that the variable is not blank

if ($fname != ''){
//
}

//OR just check it is set
if(isset($fname)){
//
}

I'm having this exact same problem I need a wildcard but I cant seem to find anything about php wildcards

 

I need mine to find any file that ends in .txt so normally it would be like *.txt but that doesnt work

Thank you onlyican, that worked perfectly.

rifts: look it preg_match

 

Wayniac: empty might be a better choice.

Thanks for the tip, is there any advantage to why I would use empty()? Is the other depreciated?

[Mchl]

It will not raise a notice if the variable tested is not set at all.

Awesome, thank you.
