for loop

[hackalive]

This code is meant to implode

	$qry_AL = "SELECT max(position) FROM `articles` WHERE `uri`='$uri'"; 
$result_AL= $mysqli->query($qry_AL, MYSQLI_STORE_RESULT);
$AL = mysqli_fetch_array($result_AL);
$AL = $AL['0'];
for($i=0;$i<=$AL;$i++) {
	$AL.$i = implode("", $AL.$i);
}

 

Basically what should happen is that $i is the maximum position value and then will implode all $AL# into just $AL#

so if max position is 9 it should loop through doing the implode for $AL0, $AL1 etc upto and including $AL9, the $i should reflect the moving up value till $i=9

 

any help would be so much appreciated, thanks in advance

$qry_AL = "SELECT max(position) FROM `articles` WHERE `uri`='$uri'"; 
$result_AL= $mysqli->query($qry_AL, MYSQLI_STORE_RESULT);
$AL = mysqli_fetch_array($result_AL);

for($i=0;$i<count($AL);$i++) {
$AL[$i] = implode("", $AL[$i]);
}

 

Something like that maybe?

[hackalive]

$AL.$i would return $AL1 etc which is required to be as such $AL[$i] is incorrect, thanks for the help though

 

any one else?

[andrewgauger]

Are you talking about different variables such as $AL1, $AL2, $AL3?

The syntax for that is ${"AL".$i}

[ChemicalBliss]

You need to use variable variables. lol, short ex:

 

$variable = "test";
$name = "variable";
echo($$name);

// results as "test"

 

So:

 

<?php

$qry_AL = "SELECT max(position) FROM `articles` WHERE `uri`='$uri'"; 
$result_AL= $mysqli->query($qry_AL, MYSQLI_STORE_RESULT);
$AL = mysqli_fetch_array($result_AL);

$AL = $AL['0'];

// Just to show you it works
$name_array = array();

for($i=0;$i<=$AL;$i++) {
$name = $AL.$i;
$$name = implode("", $AL.$i);

// Just to show you it works
$name_array[] = $name;
}

// Just to show you it works
print_r($name_array);

?>

 

-CB-

[hackalive]

okay this works

 

	$qry_AL = "SELECT max(position) FROM `articles` WHERE `uri`='$uri'"; 
$result_AL= $mysqli->query($qry_AL, MYSQLI_STORE_RESULT);
$AL = mysqli_fetch_array($result_AL);
$AL = $AL['0'];
for($i=0;$i<=$AL;$i++) {
	${'AL'.$i} = implode("", ${'AL'.$i});
}
return $AL1;

 

but I get this message

Warning: implode() [function.implode]: Invalid arguments passed in "HIDDEN BY ME"\index.php on line 123

 

line 123 is

	$result_AL= $mysqli->query($qry_AL, MYSQLI_STORE_RESULT);

 

help is much appreciated, and thanks to all those who have helped so far

[hackalive]

someone?

[hackalive]

This error is causing some serious problems for me so if anyone can help it would be much appreciated

Your code makes little sense. You are trying to define a string using implode, but the second argument your passing to implode is this same variable you haven't defined yet.

 

ps: Variable variables are slow, use an arrays instead.

[hackalive]

thorpe could you provide an example using my code above please

[trq]

Your question & code makes little sense.

[hackalive]

can you elaborate on exactly why

[trq]

Because your not providing enough information and the code examples are so far from working code that they make no sense (not to mention the fact that your variable names do NOTHING to help us know what data they store).

[hackalive]

the code get the max position (eg 1) from a table

then as a loop (for) it implodes all $AL1 arraqy data into a sting variable $AL1

then does a return

[trq]

$AL1 is not defined anywhere in your code.

[hackalive]

$AL1[0] = "hi";

$AL[1] = "and";

as an example (is predefined) pulled from another table

[trq]

$tmp = '';
for ($i=0;$i<=$AL;$i++) {
  $tmp += implode("", $AL1);
}
$AL1 = $tmp;

[hackalive]

your code cannot be used as sometimes it may get to $AL1000

it has to be completely self running (as such)

[trq]

So, where are all these $A1 - $A1000 variables defined?

[hackalive]

okay,

in a tbl field I have (as an example) AAA:

<AL1><AL2><b><AL3>

 

furthermore in another table field I have BBB:

<AL1>How is it going?<AL2>Well<AL3>Thats great

 

I have code which works that replaces <AL1> etc from "AAA" with the relevant content from "BBB"

 

finally what happens is this

	$qry_AL = "SELECT max(position) FROM `articles` WHERE `uri`='$uri'"; 
$result_AL= $mysqli->query($qry_AL, MYSQLI_STORE_RESULT);
$AL = mysqli_fetch_array($result_AL);
$AL = $AL['0'];
for($i=0;$i<=$AL;$i++) {
	${'AL'.$i} = implode("", ${'AL'.$i});
}
return $PL1

 

this code finds the max(position) in a table (eg 5), what happens is it implodes $AL1 array into $AL1 or $AL2 array into $AL2 etc

but it is resulting in the already mentioned error

 

[hackalive]

the main point is why does this error occur and why for the line previously indicated?

[trq]

And I have already explained the reason for the error. Your second argument to implode is the same variable you are trying to create. Hence, it does not exist when you pass it to implode.

 

Your code and your approach to this problem both have some serious floors in logic.

[hackalive]

thorpe can you give me code suggestion

[trq]

Not without an explination of exactly what your trying to do. We need the big picture.
