Subject: [PHP] Create Array??
Hi,
If I have a value $num = 32; based on this how can I create an Array of
numbers 1 - 32, something like this...
?
$num = 32;
$num = 32;
$iary = array();
for ($i = 1; $i = $num; $i++)
{
$iary[$i] = $i;
// if you actually wanted the array to contain 1 etc then try
// $iary[$i] = \$i\;
// Do something
}
// And now $iary = (1,2,3,etc
var_dump($iary);
?
Any suggestions?? I cannot use array_push as this has to work on a PHP3
server.
TIA
Ade

/* Untested */
$num = 32;
$i=Array();
for($x=1;$x=$num;$x++) {
$temp[$x]=0;
};
$i=array_keys($temp);
unset($temp);

Re: [PHP] Create Array??
$i=Array(); would probably be better as $temp=Array(); although i THINK
either one is redundant...
sorry

Re: [PHP] Create Array?? More
Ok,
Thanks for the input, unfortunately it didn't help me solve my overall
problem, so I will post that and see if anyone has any suggestions...
I am basically displaying the Usernames from a .htpasswd file like this...
$File=$Path$Directory1/.htpasswd;
$fd = fopen ($File, r);
$Content = fread ($fd, filesize ($File));
$Content=ereg_replace (\n,:, $Content);
// Explode the file using : as seperator
$MyContent = explode (:, $Content);
// Count it up
$LoU = count($MyContent)-1;
// Close the File
fclose($fd);
for ($a=0; $a $LoU; $a+=2)
{
printf(\nTD%s/TD%sTD/TD, $MyContent[$a], $MyContent[$a+=2]);
}
This is working perfectly, but what I would like to do is display a number
next to each one, at the moment it displays...
UserName1 UserName2
UserName3 UserName4
What I would like it to do is
1. UserName1 2. UserName2
3. UserName3 4. UserName4
I cannot figure a way to use $a because it has to skip by 2 in order not to
display the encrypted passwords..any suggestions???
TIA

Re: [PHP] create array of random unique integers?
"a" == andrew [EMAIL PROTECTED] writes:
Hi, is there a quick way to create an array of integers, randomized
and without repeats?
e.g. if my set is 1 - 10, create an array whoese key values are 1
through 10, with corresponding key values as a random set of the
same 1 through 10??
thanks in advance for any suggestions :) andrew
Yeah, this will give you an array of the numbers 1 - 10 in random
order. If you want a different range, change the parameters to suit.
?php
function rand_array( $start, $finish ) {
srand ( (double) microtime() * 100);
$rand_array = range( $start, $finish );
// it really irritates me the way PHP's sort functions mess around
// with the original array rather than returning a sorted array so
// I can assign it to where I want it.
shuffle( $rand_array );
return $rand_array;
}
print_r( rand_array(1, 10) );
?
