reading files (.htm, .php, .txt) to....

Anon

Hi,

I want to be able to read a file (a .htm, .txt, or .doc or something like that) and then arrange all the words used in that file and save them, so something like this:

file which contains:

Hello I am having some troubles this text and take out all the words and save the words with the percentages of the words used.

should give:

total words: 30
hello 1
I 1
am 1
having 1
some 1
troubles 1
this 1
text 1
and 2
take 1
out 1
all 1
the 4
words 3
save 1
with 1
percentages 1
of 1
used 1

And I would like to save this in a mysql database

Is there a way?

Sure,

Just read the file in one line at a time. Use strtok() to parse each word out one by one. As you do that use each word as they in an associative array. Voila.

$yourfile = fopen("file.txt");

while (!feof($file))
{
$currentline = fgets($file, 81);

$currentword = strtok($currentline, " ");
while ($currentword != "")
{
$arrayofwords[$currentword]++;
$currentword = strtok(" ");
}
}
blah;
blah;
blah;

Then when you're ready to output:

while ($element = each($arrayorwords))
{
echo $element[ "key" ];
echo $element[ "value"];
echo "<br>";
}

...or add it to database at this point or whatever.

thx m8,

this works with any file or just with .txt?

You can use the concept for any file, you'll just need to adjust how it handles words and stuff, cause that script just creates an array whose key is the actuall word and whose value is the number of times that word appears. So it looks like this:

$arrayofwords["hello"] = 1;
$arrayofwords["I"] = 1;
$arrayofwords["words"] = 3;
...etc

So for non-text you'll need to parse out or encode stuff that wont make good keys (like html tags).

How would you parse in a file with HTML in it?

Imagine a scenario where you have a text file with two entries per line, left side single word, right side multi-word, but with some sort of delimeter between them, say a pipe.

could you read the left side into an associative array as the name and the right side as the value? How would you do this?
