How do I write an array to a file? For example, I need to write just this in
a file:
?php $Company = array(Item 1, Item 2, Item 3, Item 4, Item 5,);
?
I've been hung up for 2 days on this. Any help would be appreciated.
Use serialize prior to writing the data to the file and unserialize
Ok, could someone tell me why this isn't working?
(note, I took out all my error checks. This is just the
relevant code...

$result = mysql( $dbname, $query );
$macroDataArray = mysql_fetch_array( $result );
for( reset( $macroDataArray ); $elementKey =
$macroDataArray = mysql_fetch_array( $result );
I'm still curious what is going wrong, but I've found a work arround.
One of the things I love about PHP is that you learn something new
just about every day. Instead of fetch_array(), I can use fetch_assoc()
and it'll do just what I need. :)
how would I write it if I wanted to say this:
if $variable == 2 through 4 ???
if(( $variable = 2 ) ( $variable = 4 )) {
echo Equals 2 through 4br\n;
}

All variables in PHP are local to the scope in which it is defined. You
cannot declare a variable as global (as such). To use a global variable:
This is true. But I believe that the original question was actually
the other way around... Make a local variable into a global one.
The way to do

function1() can echo out the value of $bob

simple add/edit/remove operations from tables.
Can you suggest a framework for this kind of job? Cause there are a lot of
tables and I hope I can find a nice tool to work with.
What database are you working with?
while( TRUE ) {
$actions++;
$words--;
}
$bets = array(1,2,3,4,5);
unset( $bets );
$arr = array( 'this', 'that', 'times' );
$arr[] = 'behind';
for( $i = 0; $i = 6; $i++ ) {
$deep++;
}
for( $i = 0; $i = 5; $i++ ) {
$flies--;
}
thnx,
Chris

Deep Six.

for( $i = 0; $i = 5; $i++ ) {
$flies--;
}
Time flies backwards? // Not sure on this one.
I wasn't sure if this one was done well enough; I guess it wasn't. The
