Body
Does it solves your problem? Use <code>$inputString</code> to put your real string. <pre><code> <?php // ------------------------------------------------------ your input goes here ------------------------------------------------------ $inputString = 'Brazil|SaoPaulo|Diadema|RuadaFe Brazil|SaoPaulo|Diadema|RuadoLimoeiro Brazil|SaoPaulo|SaoCaetano|RuadasLaranjeiras Brazil|Parana|Curitiba|ComendadorAraujo USA|NewJersey|JerseyCity|WhashingtonBoulervard USA|NewJersey|JerseyCity|RiverCourt'; class item { public $name = null; public function getChildrenByName($strName) { $ret = null; # this variable should be defined in interface, but i skipped it so it wont be printed in json when obj does not have childrens if( !isset( $this->children ) ) { $this->children = array( ); } foreach ( $this->children as $child ) { if( $child->name === $strName ) { $ret = $child; break; } } if ( !$ret ) { $this->children[] = self::spawnByName( $strName ); } return $this->children[ count($this->children) - 1]; } static public function spawnByName($strName) { $ret = new item(); $ret->name = $strName; return $ret; } } class listManager { protected $list = array(); public function getList() { return $this->list; } public function addPath( $desiredPath ) { # path needs to be as array if ( is_string( $desiredPath ) ) { $desiredPath = explode('|', $desiredPath); } # create root element if it does not already exists if ( !isset( $this->list[$desiredPath[0]] ) ) { $this->list[$desiredPath[0]] = item::spawnByName($desiredPath[0]); } $curElement = $this->list[$desiredPath[0]]; for( $i=1; $i<count($desiredPath); $i++ ) { $curElement = $curElement->getChildrenByName( $desiredPath[$i] ); } } protected function spawnElement( $strName ) { $ret = new item(); $ret->name = $strName; return $ret; } } $output = array(); $expl = explode(' ', $inputString); $list = new listManager(); foreach ( $expl as $key => $path ) { $list->addPath( $path ); } $output = ''; foreach ( $list->getList() as $singleVariable ) { $output .= json_encode($singleVariable, JSON_PRETTY_PRINT) . ",\n"; } echo '<pre>'.$output.'</pre>'; ?> </code></pre> Above code produces following json out of your sample code: <pre><code>{ "name": "Brazil", "children": [{ "name": "SaoPaulo", "children": [{ "name": "Diadema", "children": [{ "name": "RuadaFe" } ] } ] }, { "name": "SaoPaulo", "children": [{ "name": "Diadema", "children": [{ "name": "RuadoLimoeiro" } ] } ] }, { "name": "SaoPaulo", "children": [{ "name": "SaoCaetano", "children": [{ "name": "RuadasLaranjeiras" } ] } ] }, { "name": "Parana", "children": [{ "name": "Curitiba", "children": [{ "name": "ComendadorAraujo" } ] } ] } ] } { "name": "USA", "children": [{ "name": "NewJersey", "children": [{ "name": "JerseyCity", "children": [{ "name": "WhashingtonBoulervard" } ] } ] }, { "name": "NewJersey", "children": [{ "name": "JerseyCity", "children": [{ "name": "RiverCourt" } ] } ] } ] } </code></pre> edit: changed, does it fit now?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
