Stupid array question

[lZakl]

O.K. I feel REALLY dumb by posting this message, but I NEED to know. I have spent the last 2 hours going through google and have come up with NOTHING!

I need to print the entire contents of my array. I don't want it looped... I simply want my array:

$my_array = array("I", "am", "obviously", "dumb", "!")

to print like:

Iamobviouslydumb!

All I can come up with are loops that call to each variable, or the print_r method, which puts the [1], [0] and so-on in the readable text. I thought it would be as simple as:

echo "$my_array"; or
echo "$my_array[ ]"; or
echo "$my_array[]";

Nope, all I come up with when I do that is "Array". Like I said, I feel REALLY stupid, and my feelings are crushed right about now! I'm going to go crawl under my desk now, I'll check back here in an hour. I appreciate your input...

I'm no expert, but it seems that you might have to do some sort of loop.

foreach ($my_array as $key => $val) echo $val;

While we're asking stupid array questions ... :D

How can I easily obtain the number of array 'rows' that contain the same data. Ex:

$my_array = array($_ORDNUM , $_CUSTID , $_ITEMID);
$_ORDNUM will be repeated for each item I'm checking. I need to know how many of $_ORDNUM there are in this array.

For the life of me it seems so simple, but there's daylight all around me now... can't think (too) and I should be sleeping.

how about

$string = implode("",$my_array)

or

$string = join("",$my_array) //simply an alias of implode()

the first argument defines the delimiters!
(if it were " ", the returned string would be "I am obviously dumb!")

for the first question I would go with something like

echo join("", array_values($my_array));

for the second question, I assume you are talking about a multi-dimensional array? I can't see any way that you can do it without looping through the array, but it rather depends on where this is built from - you presumably pull it out of a database or flat file or something of the sort? If so, you are probably best building a supplementary array keyed on the value you want to count at the same time.

edit: just beaten to it... if you have a flat array then the previous poster is of course right that you don't need array_values but if you specify keys then you will I think.

... errr, yeah, explode might work. (What a noob I am)

It is a multi-dimensional array, and looping thru the array is out, since I'm looping thru it already in the processing. I thought about a supplemental array.. then I thought (since I've installed PHP and MySQL on this machine) just INPUT my data to a table - which may come in handy down the road.

It just adds another layer of sauce to the code. Hmmm, maybe even a meatball. But.. I can get the number of rows from that table pretty quick.

[lZakl]

$new_string = join("", array_values($my_array));

This is EXACTLY what I was looking for! Thank you guys very much! I go and eat lunch and have the brians of the world help me with my problems. A full belly, problem solved, what else could a guy ask for..?

Thanks again!
