I need to know if the following two statements will accomplish the same thing:

$installdefs["Mortgages"][][]["from"] = '<basepath>/SugarModules/relationships/layoutdefs/Accounts.php';

  'layoutdefs' => 
  array (
	0 => 
	array (
      'from' => '<basepath>/SugarModules/relationships/layoutdefs/Accounts.php',
      'to_module' => 'Accounts',
    ),
  ),
);

I know that the second will overwrite the WHOLE array. However, if that was the only thing declared for each would it be the same?

I'm asking because I have additional lines that I need to add to a PHP file. The second one is there already. I need to add more values to the array and I wanted to do it using the first method because the 0 => numbers will be different each time.

Your second code segment seems to be incomplete. The first is equivalent to this:

PHP Code:

$installdefs = array("Mortgages" =>array(array(array("from" => '<basepath>/SugarModules/relationships/layoutdefs/Accounts.php'))));

Sorry, I took only a section of the file. Here it is again:

PHP Code:

$installdefs["layoutdefs"][] = array(
     'from' => '<basepath>/SugarModules/relationships/layoutdefs/Accounts.php',
     'to_module' => 'Accounts',
 );

$installdefs["relationships"][] = array(
      'meta_data' => '<basepath>/SugarModules/relationships/relationships/accounts_fp__mortgagesMetaData.php',
);

$installdefs["language"][] = array(
    'from' => '<basepath>/SugarModules/relationships/language/Accounts.php',
    'to_module' => 'Accounts',
    'language' => 'en_us',
);

$installdefs["vardefs"][] = array(
    'from' => '<basepath>/SugarModules/relationships/vardefs/Accounts.php',
    'to_module' => 'Accounts',
); 


Is that the same as this:

PHP Code:

$installdefs = array (
  'layoutdefs' => 
  array (
    0 => 
    array (
      'from' => '<basepath>/SugarModules/relationships/layoutdefs/Accounts.php',
      'to_module' => 'Accounts',
    ),
  ),
  'relationships' => 
  array (
    0 => array (
      'meta_data' => '<basepath>/SugarModules/relationships/relationships/accounts_fp__mortgagesMetaData.php',
    ),
  ),
  'language' => 
  array (
    0 => 
    array (
      'from' => '<basepath>/SugarModules/relationships/language/Accounts.php',
      'to_module' => 'Accounts',
      'language' => 'en_us',
    ),
  ),
  'vardefs' => 
  array (
    0 =>
    array (
      'from' => '<basepath>/SugarModules/relationships/vardefs/Accounts.php',
      'to_module' => 'Accounts',
    ),
  ),
); 


No. It's close, though. Let me teach you how to fish now:

PHP Code:

print '<pre>'.print_r($installdefs,true).'</pre>'; 


that will display the array itself all prettily-formatted for you. You can then see how things vary or if they are equal.

I just used the following code to test it and the resulting arrays look identical to me:

PHP Code:

<?php
$installdefs1 = array (
  'layoutdefs' => 
  array (
    0 => 
    array (
      'from' => '<basepath>/SugarModules/relationships/layoutdefs/Accounts.php',
      'to_module' => 'Accounts',
    ),
  ),
  'relationships' => 
  array (
    0 => array (
      'meta_data' => '<basepath>/SugarModules/relationships/relationships/accounts_fp__mortgagesMetaData.php',
    ),
  ),
  'language' => 
  array (
    0 => 
    array (
      'from' => '<basepath>/SugarModules/relationships/language/Accounts.php',
      'to_module' => 'Accounts',
      'language' => 'en_us',
    ),
  ),
  'vardefs' => 
  array (
    0 =>
    array (
      'from' => '<basepath>/SugarModules/relationships/vardefs/Accounts.php',
      'to_module' => 'Accounts',
    ),
  ),
);  


$installdefs["layoutdefs"][] = array(
     'from' => '<basepath>/SugarModules/relationships/layoutdefs/Accounts.php',
     'to_module' => 'Accounts',
 );

$installdefs["relationships"][] = array(
      'meta_data' => '<basepath>/SugarModules/relationships/relationships/accounts_fp__mortgagesMetaData.php',
);

$installdefs["language"][] = array(
    'from' => '<basepath>/SugarModules/relationships/language/Accounts.php',
    'to_module' => 'Accounts',
    'language' => 'en_us',
);

$installdefs["vardefs"][] = array(
    'from' => '<basepath>/SugarModules/relationships/vardefs/Accounts.php',
    'to_module' => 'Accounts',
);  

echo '<pre style="border: 2px solid black; padding: 1em; margin: 20px;>'.print_r(get_defined_vars(),true).'</pre>';
?>

They are.

Thanks Mattias. He's right. I thought your second arrays included the very first at in your original post. That one has an additional array of nesting which was missing. The last 2 are equal.

Sorry about that!

No worries... Thanks for the help!
