how to remove "comma, full stop" from a sentence

kenny873

hello,

i have sentences as follow:

$quote[1] = "To be or not to be, that is the question.";
$quote[2] = "Love looks not with the eyes, but with the mind.";
$quote[3] = "Love all, trust a few. Do wrong to none.";

now I would like to do the following,

1) for each quote[$i], remove all ","(comma) or "."(full stop)...does anyone know how? I have the following code but it does not work. What should I write in $patterns?

for ($i=1; $i<4; $i++)
{
$quote[$i] = strtolower($quote[$i]);
echo "$quote[$i]<BR>";
$pieces = explode(" ", $quote[$i]);
for ($j=0; $j< (count($pieces)); $j++)
{
echo "$pieces[$j] ";
$patterns = ".\";
$replacement = "";
print preg_replace($patterns, $replacement, $string);
echo "$pieces[$j] <BR>";
}
}

2) also, I would like to count a) number of frequecy of each term (e.g. "to" has a frequency of 2 in qoute[1]) and b) number of frequency for all three quotes (i.e. "to" has frequency = 3)

but I have no idea how? can anyone please give me an idea?

Thank you very very much.

You can use str_replace?

thanks you very much...

One more question, if all the three sentences are read from another file, for example:

quote.txt has the following;

To be or not to be, that is the question.
Love looks not with the eyes, but with the mind.
Love all, trust a few. Do wrong to none.

1) how do I read this file?
2) how do I do the same as I wanted to do before?

Thank you very much for your kind help

barand

$quote[] = file_get_contents('quote.txt');

Then process as now.

thanks....it does work partly.

because it only shows as one array instead of three?

how do I recognize it as 3 arrays because it has three sentences (I hit an Enter after each sentence)

barand

$quote = file('quote.txt');

That will split the file at each newline and create array elements.
