Regex newbie

[gazza67]

Anybody,

I want to use a regex in which the string for which we are searching
is a variable. Is this possible - it doesnt seem to work for me.

$a = "be";

$b="to be or not to be";
if ($b =~ m/$a/i )
print "this should be true";

$b = "apples and oranges";
if ($b =~ m/$a/i )
print "this should be false";



Cheers
Gary

Either you have to use post condition or have to close block after if
statement with brackets

print "this should be true" if ($b =~ /$a/i);

or

if ($b =~ /$a/i){
print "this should be true";
}
