[PHP] random number problem...
Hi, I've written a picture rotation script, file paths are stored in a file and are called depending on a random number generator.. The problem is that out of 14 possible numbers only 7 are been generated. the code I'm using is... srand ( (double) microtime()*1000); $numbertodisplay = rand(0, (($no_items)-1)); The variable $numbertodisplay only ever takes the values 0,2,4,6,8,10,12. Is there a reason that the only numbers produced are even? Thanks for any help.. James
[PHP] Variables
Hi,
This might sound really simple but plz humour me :)
How can I tell if two text variables are equal to one another?
If I use..
if($text1 = $text2)
{
echo The variables are equal;
}
else
{
echo The variables are not equal;
}
then the code in the else state is always printed even if I know for a fact that the
variables are equal...
Any suggestions?
James
Re: [PHP] Variables

No it doesn't seem to like that either...
The weird thing is that if I used instead of = it's fine...although that
is not the result I want...

Try
if($text1 == $text2)
{
echo The variables are equal;
}
else
{
echo The variables are not equal;
}
notice the change in the if()

Thanks for any advice.

[PHP] Problem writting to file...
Hi,
I'm trying to write data to a file but for some reason it will not store numbers in
the file...Here's the code I'm using...(as an example)
?php
$fp = fopen(./data.txt, w+);
$counter = 0;
while ($counter 6)
{
fwrite($fp, $counter . \n);
$counter = $counter +1;
}
fclose ($fp);
?
Thanks for any help...
James
Re: [PHP] Problem writting to file...
nope...
The 'new line' tages are printed inside the file but not the values produced by the
counter...

I don't see anything wrong with the code. Does this work:
?php
$fp = fopen(./data.txt, w+);
$counter = 0;
for($counter = 0; $counter 6; $counter++)
{
fwrite($fp, $counter . \n);
}
fclose ($fp);

Re: [PHP] Problem writting to file...
When I use that code I get the following...
Counter is = 0
Counter is = 1
Counter is = 2
Counter is = 3
Counter is = 4
Counter is = 5
However if you remove the Counter is = part then once again no numbers are written,
only the 'new line' symbols...

Sometimes you have to do this to make it work.

[PHP] Writting to files.?
Hi, Anyone know how I can write and read to different lines in a file rather than just adding to the text already on the first line of the file? Thanks Zotud
Re: [PHP] Writting to files.?
Thanks for the response so far... I'm still not sure on how to get the code to start on a new line in the file (yes they are text files). Say I wrote variable1 to line one how do I get it to write the next variable to line two?

Thanks Assuming you're talking about text files: A. suck the whole thing up in memory, change it there, write it back out. B. open a temp, copy till the line of interest, write your change, copy remainder. mv/cp the temp to the original. C. read to line of interest, ftell(), suck remainder into memory. ftruncate(), fseek(), write your changes, write out the remainder.
