php - Delete part of index name in multidimensional array -

in php, possible cut |xyz part away key names? array looks this:

    array(30) {   ["1970-01-01|802"]=>   array(4) {     ["id"]=>     string(3) "176"     ["datum"]=>     string(10) "1970-01-01"     ["title"]=>     string(8) "vorschau"     ["alias"]=>     string(16) "vorschau-v15-176"   }   ["1970-01-01|842"]=>   array(4) {     ["id"]=>     string(3) "176"     ["datum"]=>     string(10) "1970-01-01"     ["title"]=>     string(8) "vorschau"     ["alias"]=>     string(16) "vorschau-v15-176"   } ... 

thank help,

for example, might use this:

$newarray = array(); foreach( $oldarray $key => $value ) {     $newarray[ substr( $key, 0, 10 ) ] = $value;  } 

or modify array in-place:

foreach( $somearray $key => $value ) {     unset( $somearray[ $key ] );    $somearray[ substr( $key, 0, 10 ) ] = $value;  } 

both solutions loose value

since keys in source array are

   1970-01-01|802    1970-01-01|842 

the output array loose array values: both keys mapped single destination key:

   1970-01-01 

keeping values

if don't want loose values, try this:

$newarray = array(); foreach( $somearray $key => $value ) {     $newkey = substr( $key, 0, 10 );    if ( ! isset( $newarray[ $newkey ] )) {       $newarray[ $newkey ] = array();    }    $newarray[ $newkey ][] = $value;  } 

result array structure of solution:

array(    '1970-01-01' =>      array(        0 => ...,        1 => ...     ),   '1970-01-02' =>      array(        0 => ...,        1 => ...,        2 => ...     ),   ... );
