A "for" structure that doesn't work :-(

[Anon]

This is a stupid piece of code that is making me crazy: why the for loop doesn't work ??

//name of the file to read into an array
$filegroup="/path/file.grp";
$users = file($filegroup);

echo ("<br>String of words in array at position 0 are: <br>".$users[0]."<br>");

//Now a new array is made and each word of the string is inserted into one array cell.

$pieces = explode (" ", $users[0]);
$lenght = sizeof($pieces);
echo ("<br>The number of records into array pieces is: ".$lenght);

//this is the stupid for loop that doesn't work.

for($cont=1; $cont<$length; $cont++)
{
echo $pieces[$cont];
echo $cont;
}

Thank for any help about

And what exactly does it not do?

[Anon]

It does nothing:

it should output something like:

word1
1
word2
2
word3
3
word4
4
...

but it does absolutely nothing and I don't understand why...

thanks for the help.

Adn $length is more than 1?

[Anon]

The lenght was 5.

I think that the trouble is related in some way to the word "lenght".

I have only changed the word "lenght" into "size" and now it works.

Really I cannot understand why :-??

Looks like it is just a typo. You set the value of $lenght, but use the value of $length in your for loop.

$pieces = explode (" ", $users[0]);
$lenght = sizeof($pieces);
echo ("<br>The number of records into array pieces is: ".$lenght);

//this is the stupid for loop that doesn't work.

for($cont=1; $cont<$length; $cont++)
{
echo $pieces[$cont];
echo $cont;
}

As Steve pointed out, and as I seem to have missed,
you sometimes spell length as "lenght" which mean you are setting and checking to completely different variables.

Thanks Steve!
