[RESOLVED] Attempting to get values from array

[cupboy]

<?php
// sample data:
$a[] = array(array("edt"=>"edttl"), array("col"=>"str_team_lead"), array("delimiter"=>chr(39)));
//$a[] = array(array("edt"=>"edtFirst"), array("col"=>"str_fname"), array("delimiter"=>chr(39)));
//$a[] = array(array("edt"=>"edtLast"), array("col"=>"str_lname"), array("delimiter"=>chr(39)));
$edt = "";
$col = "";
$delim = "";

foreach ($a as $aa) 
  foreach ($aa as $key=>$val)
    switch($key)
    {
      case "edt":
        $edt = $val;
      case "col":
        $col = $val;
      case "delimiter":
        $delim = $val;
    }        
// results: col=Array, delim=Array, edt=Array 

// desired results: col=str_team_lead, delim=', edt=edttl

print "col=$col, delim=$delim, edt=$edt <br />";

// some poor examples at :
// http://us.php.net/manual/en/control-structures.foreach.php

Same thing you try to do with switch-case
can be done within the foreach loop

if $key = 'col'
then
$$key means $col

Note also I have changed
$a[] = array(array("edt"=>
to
$a = array(array("edt"=>
There is no reason here to use $a[]

<?php

$a = array(array("edt"=>"edttl"), array("col"=>"str_team_lead"), array("delimiter"=>chr(39)));

foreach($a AS $aa){
	foreach($aa AS $key=>$val){
		$$key = $val;
	}
}
print "col=$col, delim=$delim, edt=$edt <br />";

?>

That works for the example, but how about this one?

<?php
$a = array(array("edt"=>"edttl"), array("col"=>"str_team_lead"), array("delimiter"=>chr(39)));
$a[] = array(array("edt"=>"edtFirst"), array("col"=>"str_fname"), array("delimiter"=>chr(39)));
$a[] = array(array("edt"=>"edtLast"), array("col"=>"str_lname"), array("delimiter"=>chr(39)));
$col = "";
$delimiter = "";
$edt = "";
$row = 0;
foreach($a AS $aa){
    $row++;
    foreach($aa AS $key=>$val){
        $$key = $val;
    }
    if ($row == 3)
    {
      print "Results = col=$col, delim=$delimiter, edt=$edt <br />";
      $row = 0;
    }
}
print "End values: array count " . count($a) . " row $row col $col delim $delimiter edt $edt <br />";
print_r($a); // the array doesn't look like I would expect it to
?>

Another function
that can make normal variables from an array
is [man]extract/man

Is useful for exampel when get values from $POST
after a form has been submitted.
A little warning: Need to care for that the same variabel names
not already exist in your script.
Or they can be destroyed and overwritten by extract()

<?php
/*
extract($_POST)
will pull out all posted fields as normal variables
for example: $name, $email, $city
*/

$Post = array(
'name' => 'John Doe',
'email' => '[e-mail]',
'city' => 'New York'
);

// pull out variables
extract($Post);

echo 'name: '.$name.'<br />';
echo 'email: '.$email.'<br />';
echo 'city: '.$city.'<br />';

?>

Well nevermind on this whole thing. I was just doing the array wrong. I've got it working the way I want now.

print "<br />=============NEW TEST=======================<br />";
$a2[] = array("edt"=>"edttl","col"=>"str_team_lead","delimiter"=>chr(39));
$a2[] = array("edt"=>"edtFirst","col"=>"str_fname","delimiter"=>chr(39));
$a2[] = array("edt"=>"edtLast","col"=>"str_lname","delimiter"=>chr(39));
print_r($a2);
print "<br />============================================<br />";
