I can't find instances of square brackets in a string under all
conditions. for example:
the expression below will find the left bracket, however if I make the
$excludeChars="\[\]" it will not find either bracket in the example
regardless of which bracket is in the example. Like wise "\]" will not
find the right bracket...however, "\[" will find the left bracket. I
have no idea what is going on.
$excludeChars="\[";
$text="when in t[he course of human events";
if(ereg("([$excludeChars])",$text)){
Print("bad chara\n");
}
else
{
Print("ok to use");
}
I checks docs, my ref book, I've looked for examples and nothing....any
help or pointers to info appreciated.
