I guess what you're suggesting is a lot like using a relative URL in a
redirect... it works, it saves some time, but it's not quite right ;)

OK Chris,
I understand that we're checking checking the form data and escaping it, butcan explain what's going on in the WHERE clause and 1=1 tad bit more.
Instead of looking at all records in your original attempt (which willwork fine for 10 records), you limit what you are looking at (whichworks a lot better for 50,000 records).
The 1=1 is something that the database will remove internally butbasically it stops an invalid query:
select * from table where a='b' and c='d' and

That's why I said you can either remove the last and:

select * from table where a='b' and c='d'

or

add 1=1:

select * from table where a='b' and c='d' and 1=1

They work out the same.

let's say we have the following associative array:

$array = array(
 "red" => "ferrari",
 "yellow" => "volkswagen",
 "green" => "mercedes",
 "blue" => "volvo"
);

then we have a current index into the array:

$index = "yellow";
$current = $array[$index];

now: how do i get the key of the next array element (in this case "green")?

$next = ?

Why not define your array with number index as well in the first place?

Funnily enough:

$next = next($array);

Give this a shot

<?php

function array_next($ar, $curr) {
        $capture = false;
        $next = '';
        foreach ( $ar AS $k => $v ) {

                        return array($k => $v);
                }
                if ( $k == $curr ) {
                        $capture = true;
                }
        }
        return $next;
}


$array = array(
 "red" => "ferrari",
 "yellow" => "volkswagen",
 "green" => "mercedes",
 "blue" => "volvo"
);

print_r( array_next($array, 'yellow') );

chris

for your suggestion to work, the internal array pointer of $array
would first have to be set to point to the current element ($index).

but how do you do this?

this may seem like childs play, but i actually can't find any
documented php function for this. it would be something like:

array_set_internal_pointer($array, $index);

yep, a for loop is the fallback i use now.

any reason why there isn't a built-in function for this?

any plans for it in future versions of php?

Hi Folks,

Is there a better way of doing the following:

$Rows[] = array();
$currentRow = count($Rows) - 1;
$Rows[$currentRow]['test'] = "this is a test";

Specifically I am wonder if I can avoid having to use 'count'.

TIA,
 JC

This code looks weird...

$currenRow will be numeric. So why would you do $currentRow['test']?
Anyway if you just wanna add an element to the end of the array use array_push

1) The code above will produce a $currentRow of -1 which is probably notwhat you want.
2) If you actually mean that you have an array that contains items andyou want the last one, used end (http://php.net/end).
3) I'm not really sure what the context is, but this is a very odd wayof working with arrays. Either you already know the key or you don't. Ifyou're just trying to append to the array you can do that with thefollowing syntax... $Rows[] = array('test' => 'this is a test');

Seems my eyes are to tired today. Didn't read the code very good.
But the answer still stays the same :)

$Rows = array();
array_push($Rows, array('test' => 'this is a test'));

Maybe you didn't notice the [] in the first line of the OP's code?
I think this code should produce 0 for $currentRow, not -1.

Indeed, my bad. In that case the OP is better off creating the item in atemporary variable and then adding it to the array.
$row = array();
$row['test'] = 'this is a test';
$Rows[] = $row;

Nothing, unless you're building a complex element. I was assuming thatthe OP had simplified their code down to the minimum required toillustrate the problem.

I wouldn't be leery at all. It's been around for a very long time and

As soon as I hit send I knew that would be mis-interpreted...

Leery is the wrong word.

Sorry.

It just seems a bit to clever to me...

I suspect I'd skim this code a hundred times and not realize what it

But maybe that's just me. :-)
I would have to agree. I'm a big fan of self-documenting code, and thisone requires a little bit more knowledge of the intricacies of PHP thanI would expect from your 'average' developer.
If performance is going to be an issue (and in terms of cycles I can'tsee this saving much), buy faster/more hardware - it's far cheaper thandeveloper time!!

what do you mean by 'cannot do' ?

If I do:
<?php
$string = "part1 ' part2";

it will return

Hi,

Problem was

$strng = "'cInputI' style='width:146px;'>";
$arrExplode = explode("'",$string);

$arrExplode contins

[array][1]
    * "0"=>[string]['cInputI' style='width:146px;'>]

And not only explode for example I canot trim first "'"

Omg, It's my bad, sorry for lameness. 

Before the exploding text I do some encoding decodings. 

So? I do mis sequenced decodings. Thats why it does not work explode or trim, 
or str_replace even all other string functions.
