php array comperation, complete missing array locations -

i have 2 arrays:

 $array1 = array('name', 'email', 'phone');  $array2 = array('name' => 'john', 'phone' => '55-555-555'); 

i have created html table 2 arrays, array1 table heads, , array2 td contents.

what happens becouse array2 missing value (email in case) phone data under mail column. result:

 $array2 = array('name' => 'john', 'email' => ' ', 'phone' => '55-555-555'); 

i tried follow this answer, has 2 main problems:

1. the array keys desapear.
2. the 0 values added @ end of array , not in original location.

your source array wrong. need have this:

$array1 = array('name' => '', 'email' => '', 'phone' => ''); 

and if want extend empty values, can use:

$array2 = array('name' => 'john', 'phone' => '55-555-555'); 

the final array can made using array_merge:

merges elements of 1 or more arrays values of 1 appended end of previous one. returns resulting array.

$array2 = array_merge($array1, $array2); 

you output:

array('name' => 'john', 'email' => '', 'phone' => '55-555-555'); 

full code

$array1 = array('name' => '', 'email' => '', 'phone' => ''); $array2 = array('name' => 'john', 'phone' => '55-555-555'); $array2 = array_merge($array1, $array2); var_export($array2); 

output

array (   'name' => 'john',   'email' => '',   'phone' => '55-555-555', )

better explanation

// have base array has required fields. $basearr = array('name', 'email', 'phone', 'password'); // array initial values, (without few fields). $myarray = array('name' => 'david', 'email' => 'aaa@aaa.aaa', 'phone'=> '123456789'); // make new array on fly array_fill_keys using basearr // , merge original user array. $myarray = array_merge(array_fill_keys($basearr, ''), $myarray); // resultant array have fields. print_r($myarray); 

output

array (     [name] => david     [email] => aaa@aaa.aaa     [phone] => 123456789     [password] =>  )
