[SOLVED] HELP With an Array and foreach

[JSHINER]

I have the following

 

<?php 
												$APPLIANCES = ARRAY (
												// Breaks up A,C to two separate variables to be used later
												$a => substr($page['details']['APPLIANCES'], 0, 1),
												$b => substr($page['details']['APPLIANCES'], 2, 1)

												);
												// Pulls from a table which defines the Short and Long meanings of AMENITIES
												foreach ($page['references_amenities'] as $z) {

$$z['Short'] = $z['Long'];

												}

//Groups the A,C variables from above with their Long meanings from above. So if $a = C it should display the Long meaning based on the Short being equal to C

foreach ($PPLIANCES as $y) {

												if($y=$z) { echo $z['Long'];}

												} 
												?>

 

 

Where is my error above? It is not working.

 

I first set up JUST the foreach with $z['Short'] and $z['Long'] and it worked - displayed "A - First, "B - Second" and so on.

 

[paul2463]

you have a spelling mistake in your foreach statement, you have a missing "A" from your $APPLIANCES

[JSHINER]

Thanks. However the last foreach is still not working correctly.

 

It is just displaying the last Long from the previous foreach.

post the values of all your variables. what is it doing. what is it supposed to be doing?

[JSHINER]

The $APPLIANCES array is taking a value from a database that is stored as "A,B,D,E" or something like that - letters vary.

 

I need to split each letter of that up into its own variable, so I created that ARRAY so $a = A, $b = B, $c = D, etc

 

I then need to cross reference those $a, $b variables with the results of the $page[references_amenities] which each result looks like A - Long Name .... their fields are $z['Short'] - $z['Long']

 

So based on the $APPLIANCES array, I need the $a to match up to the corresponding $z['Short'] and then display the $z['Long'] value for that.

 

I hope that makes sense.

[boo_lolly]

sorry, that doesn't make any sense. you probably need to post more code.

[Koobi]

i make this mistake a lot too which is probably why i caught this out

 

<?php
if($y=$z) { echo $z['Long'];}
?>

 

 

in the above, you are trying to assign $z to $yz and an assignation will always work...unless you are trying to assign a value to a previously defined constant and therefore, your if condition will ALWAYS be true.

 

you have to use either '==' or '===' depending on your needs.

 

 

what happens in between the if conditions brackets is that the code in there is evaluated (think var_dump()) and the if condition itself receives the boolean result of what is in the brackets.

so, you assigning $z to $y will always return a true to IF since that is a perfectly legal thing to do in PHP.

 

 

 

 

 

btw, you can correct your code by making it like this:

<?php
if($y == $z) { echo $z['Long'];}
?>

[JSHINER]

Thanks.

 

However, the if($y == $z) echo $z['Long'] is still not working correctly.

 

I am not sure if I am doing this correctly. Here is my current code:

 

<?php 
												$APPLIANCES = ARRAY (

												$a => substr($page['details']['APPLIANCES'], 0, 1),
												$b => substr($page['details']['APPLIANCES'], 2, 1)

												);

												foreach ($page['references_amenities'] as $z) {

												$z['Short'] = $z['Long'];


												}

												foreach ($APPLIANCES as $y) {

												if($y == $z) { echo $z['Long'];}

												} 

												?>

[Koobi]

try working backwards then.

 

check the results of $z like this:

<?php
    echo '<pre>' . print_r($z, true) . '</pre>';
?>

 

and if $z does contain what you expect, then go backwards and do the same for $page, etc until you see something that we might find useful to solve this problem and post it here.

 

 

 

 

 

also, you had this earlier:

<?php
$$z['Short'] = $z['Long'];
?>

 

 

but now you have this:

<?php
$z['Short'] = $z['Long'];
?>

 

just pointing it out because your code would have failed earlier anyway.

[JSHINER]

Using the following:

 

$APPLIANCES = ARRAY (

$a => substr($page['details']['APPLIANCES'], 0, 0),
$b => substr($page['details']['APPLIANCES'], 2, 1)

);

foreach ($APPLIANCES as $y) {

echo '', $y, ' > ';

} 

 

Now when I simply do "echo $page['details']['APPLIANCES']" I get A, C

 

However, when I do that foreach echo '', $y, '>'; It only displays C >

 

What am I missing here?

[trq]

What does...

 

print_r($APPLIANCES);

 

produce?

[JSHINER]

print_r($APPLIANCES);

 

Produces...

 

Array ( [] => C )

[JSHINER]

OK so I changed the ARRAY to:

 

$APPLIANCES = ARRAY (

'$a' => substr($page['details']['APPLIANCES'], 0, 0),
'$b' => substr($page['details']['APPLIANCES'], 2, 1)

);

foreach ($APPLIANCES as $y) {

echo '', $y, ' > ';

} 

 

put ' ' around $a and $b

 

 

[trq]

And?

 

What does...

 

print_r($APPLIANCES);

 

produce now?

[JSHINER]

print_r($APPLIANCES);

 

Now produces:

 

Array ( [$a] => A [$b] => C )

 

Which is now correct.

 

Now how can I get that to work with the $z['Short'] and $z['Long']

 

So if $a == $z['Short'] it will display the corresponding $z['Long']

[trq]

Now how can I get that to work with the $z['Short'] and $z['Long']

 

So if $a == $z['Short'] it will display the corresponding $z['Long']

 

Sorry? What do you want to do?

[JSHINER]

I have a function that pulls the values for Short and Long from a database. So for example a Short would be A, Long would be Tiger

 

So I want that if the $a is A, it would display Tiger instead of A

 

I'm thinking of using a foreach to set the values for Short and Long. I tried:

 

foreach ($page['references_amenities'] as $z) {

$z['Short'] = $z['Long'];

}

 

But that does not work.

[trq]

Example.

 

<?php

  // connect to db
  $sql = "SELECT short,long FROM tbl";
  if ($result = mysql_query($sql)) {
    if (mysql_num_rows($result)) {
      $values = array();
      while($row = mysql_fetch_assoc($result)) {
        $values[$row['short']] = $row['long'];
      }
    }
  }

?>

[JSHINER]

This is what I currently use to bring the array of Long and Short in. It pulls from the database. Is there anyway I can create a relationship between the two here?

 

foreach ($page['references_amenities'] as $z) {

$z['Short'] = $z['Long'];

}

 

 

Then - how do I make it so if the $a from the $APPLIANCES array = Short, it will display Long ?
