assuming that you are not using other options of array_multisort(), why not do
something like this.
$ar = array_merge($array1, $array2, $array3);
natsort($ar);

Hi there! Correct me if I'm wrong but merge() just makes one array of all
items. array_multisort() keeps each array separate, while applying the same
re-ordering to all three arrays. This allows you to use the same position
number to get the required elements from each array, especially where each
array is a list of different properties. For example:
$name = array("Joe", "Charlie", "Jack");
$age = array(30, 12, 66);
$job = array("Plumber", "Student", "Retired");
array_multisort($name, $age, $job); // will re-order all three arrays based on
a "regular" alphanumeric sort of the names:
// $name is now array("Charlie", "Jack", "Joe");
// $age is now array(12, 66, 30);
// $job is now array("Student", "Retired", "Plumber", );
// can now do:
$firstName = $name[0]; // returns "Charlie"
$firstAge = $age[0]; // returns Charlie's age 12
$firstJob = $job[0]; // returns Charlie's job "Student"
A merge of these arrays will lose the different types of info each array
currently has, and make it impossible to match a name to the age or job.
Now, my other option is to group the items into a set of arrays:
$array1 = array('name' => 'Joe', age => '30' job => 'Plumber');
$array2 = array('name' => 'Charlie', age => '12' job => 'Student');
$array3 = array('name' => 'Jack', age => '66' job => 'Retired');
$largeArray = array($array1, $array2, $array3);
But, is there a way to the sort $largeArray, based on the "name" value in each
individual array? And if so, can that use the natsort()? I don't think an
asort() can do either.
Note that the original source of this info is a mySQL db call, and it is
initially sorted in the query, but again, there doesn't appear to be a way to
natural sort an SQL query either. So I get file1, file10, file2, file20,
file5.... instead of file1, file2, file5, file10, file20....

Based upon code I found at [1] I have the following function [2] which
I use to sort result sets. I've just added natural sorting (and
natural caseless sorting) and some examples on usage.
It might be slightly over the top, but it works well for me. No need
to extract the columns from the rows to supply to the sorter.
If you like it and find any issues with it, or enhancements, then I'd
be grateful if you could pass them back to me.
Richard.

I believe it was in the Old PHPestament,
"The Book of Rasmus" chapter 42 verse 69...
66 ...
67 And behold as he opened the 5th point 2nd seal
68 and the Lord said unto him,
69 "Thou shalt not use frameworks,
70 for they art cumbersome
71 and a bastardization of mine own language"
72 ...
It goes on to talk about using "<?=" instead of "<?php echo"
And how you should always put the closing "?>" on the page bottom,
But I digress...
ROFL! :D

Nah, if he'd read it backwards, you'd be able to hear MePHPistoPHPeles
say, "Rasmus is the Penguin".

Hello Gary,
Try using this:
if (!empty($beefolives)) $msg.="Order: beef olives";
or:
$msg.=empty($beefolives)? "": "Order: beef olives";

Subject: [PHP] empty() in email message
I have an email message
$msg = 'Name: $fname ' . ' $lname\n'
. "Phone: $phone\n"
. "Email: $email\n"
and it works fine, however in this message there are about 30 variables that
are being called...as such
. "Order: beefschnitzel $beefschnitzel\n"
. "Order: beefstrips $beefstrips\n"
. "Order: cheesesausage $cheesesausage\n"
. "Order: crumbedsausage $crumbedsausage\n"
. "Order: chucksteak $chucksteak\n"
. "Order: cornedbeef $cornedbeef\n"
. "Order: dicedsteak $dicedsteak\n"
. "Order: filletmignon $filletmignon\n"
I want to only send the message if the submitter enters an amount in the
form for the corresponding variable, instead of having a bunch of empty
messages. So I have been trying to use the empty() function as such:
. if empty($beefolives){''} elseif (isset($beefolives)) { 'Order: beefolives
$beefolives\n'}
But I am getting the error
Parse error: syntax error, unexpected T_IF
Can someone point me in the right direction?
Thank you

You are setting this up fundamentally wrong.
You should be using an array and looping through it.
Something like:
$myorder['cowface'] = 1;
$myorder['beefenweiner'] = 2;
$myorder['chucksteak'] = 1;
foreach ($myorder as $item => $quantity)
{
echo "Order: $item x $quantity\n";
}
Then your array only contains the items someone actually puchased and how
many.

Less complication is better, reduce the code to the below. The empty
portion needs to be inside the parentheses. Also double quotes are
needed to make the vairable parse correctly into the value you want to
see
if (!empty($beefolives)) { echo "Order: beefolives $beefolives\n";}

Thank you for your response, and I agree, I like simpler. Your script
however did not work in the email message, it did work in another section
where I echo to screen the information to the screen.
Does the echo command work in emails?
Thank you again.

Thank you for your reponse. I will admit I get a little fuzzy on the single
v double quotation marks, generally the rule I go by is if it is a string, I
use singles, if any processing I use doubles. I am not recalling why did it
that way, perhaps I had doubles and it did not work so I was whittling down
the options....
Thank you again for your help.

That's because you're concatenating. When appending to a
variable, you can't use constructs and conditions, unless using
ternaries:
. (!empty($beefolives) && is_numeric($beefolives) ? 'Order: beefolives
'.$beefolives : null)
However, for readability and ease of management, you might want to
try something like this. It makes at least two assumptions: you're
using a form post, and you understand that it's untested (as I'm just
typing it here into the body of this email).
<?php
// If we've posted our order
if (isset($_POST) && is_array($_POST['order'])) {
// Instantiate the $order variable
$order = null;
// Iterate the order quantities
foreach ($_POST['order'] as $k => $v) {
// If the field is set and the amount is a number
if (isset($v) && is_numeric($v)) {
$order .= 'Order: '.$k.': '.$v.PHP_EOL;
}
}
/**
* Note: in your example, you used single (literal)
* quotes and included the variables. That would
* literally print $fname and $lname.
*/
$msg = 'Name: '.$_POST['fname'].' '.$_POST['lname'].PHP_EOL;
$msg .= 'Phone: '.$_POST['phone'].PHP_EOL;
$msg .= 'Email: '.$_POST['email'].PHP_EOL;
$msg .= PHP_EOL;
$msg .= $order;
// And then handle the rest of your processing. Here, we just echo.
echo '<pre>'.PHP_EOL.$msg.'</pre>'.PHP_EOL;
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

As always, thank you for your input. I had tried your first script, and it
worked to a degree. What I was getting was a message that was correct, but,
well, this is what it looked like in an email
Order: beefschnitzel
10Order:
Which was supposed to look like
Order: beefschnitzel 10
Order:
I have not tried your second suggestion yet, I'll let you know how that
works.
Again, thank you for your help.

I knew someone was going to point out this was a convoluted method, and I
agree. This was sent to me by someone that needed to make the mail form
work. My suggestion was to look into a pre-made shopping cart, however that
was not going to work for them, so I made the mail() work for them.
I had thought about putting it into an array, but had not gotten that far
into it. I will look over the code to see how it works.
Thank you for your help.
