Add key and value to existing array

Question

I need to add a key and value to an existing array and don't seem to get it together.

My existing array when printed is as follows:

Array ( [0] => stdClass Object ( [id] => 787 [name] => Steve [surname] => Ryan [email] => [e-mail] ) [1] => stdClass Object ( [id] => 1057 [name] => Peter [surname] => Smith [email] => [e-mail] ) [2] => stdClass Object ( [id] => 1058 [name] => Chris [surname] => Gill [email] => [e-mail] ) ) 

I need to add some details to this array on the fly from string , which looks like this:

 Topher: [e-mail] Elvis: [e-mail] Marilyn: [e-mail] 

Each entry is separated by the new line symbol, and the name and email address are separated by the symbol :

So at the end, my array will look like this:

 Array ( [0] => stdClass Object ( [id] => 787 [name] => Steve [surname] => Ryan [email] => [e-mail] ) [1] => stdClass Object ( [id] => 1057 [name] => Peter [surname] => Smith [email] => [e-mail] ) [2] => stdClass Object ( [id] => 1058 [name] => Chris [surname] => James [email] => [e-mail] ) [3] => stdClass Object ( [id] => [name] => Topher [surname] => [email] => [e-mail] ) [4] => stdClass Object ( [id] => [name] => Elvis [surname] => [email] => [e-mail] ) [5] => stdClass Object ( [id] => [name] => Marilyn [surname] => [email] => [e-mail] ) ) 

I looked at array_push but couldn't handle it.

Any help on this is very much lit.

Answer 1

Using PHP Arrays' [] is the same as pushing a value to the end of an array.

 $arr[] = 'new element in array'; 

A complete solution for your example would be

 $CharacterInput = <<<EOT Topher: [e-mail] Elvis: [e-mail] Marilyn: [e-mail] EOT; $lines = explode("\n", $CharacterInput); $People = array(); foreach($lines as $line) { list($name, $email) = explode(':', $line); $entry = array( 'id' => null, 'name' => $name, 'surname' => null, 'email' => $email, ); // cast the entered data array to an object, // which is explicitly stated in the example output. // For plain arrays, remove the following line. $entry = (object) $entry; $People[] = $entry; } print_r($People); 

which outputs

 Array ( [0] => stdClass Object ( [id] => [name] => Topher [surname] => [email] => [e-mail] ) [1] => stdClass Object ( [id] => [name] => Elvis [surname] => [email] => [e-mail] ) [2] => stdClass Object ( [id] => [name] => Marilyn [surname] => [email] => [e-mail] ) ) 

Answer 2

You can try something like this

 $string = "Topher: [e-mail] \nElvis: [e-mail] \nMarilyn: [e-mail] "; $string = explode("\n", $string); $result = array(); # or your existing array foreach($string as $chunk){ $to_array = new stdClass(); $to_array->id = null; $to_array->surname = null; list($to_array->name, $to_array->email) = explode(':', $chunk); $result[] = $to_array; } print_r($result); 

Codepad Code Example

Result:

 Array ( [0] => stdClass Object ( [id] => [surname] => [email] => [e-mail] [name] => Topher ) [1] => stdClass Object ( [id] => [surname] => [email] => [e-mail] [name] => Elvis ) [2] => stdClass Object ( [id] => [surname] => [email] => [e-mail] [name] => Marilyn ) ) 

Answer 3

Assuming $ arr is your existing array variable, do it as follows.

 $arr[] = array( ['id'] => '', ['name'] => 'Topher', ['surname'] => '', ['email'] => ' [e-mail] ' );
