    <p>I need a help. I'm looking for a solution for this problem! I have a file which contains the following pattern:</p> <blockquote> <p>Brazil|SaoPaulo|Diadema|RuadaFe Brazil|SaoPaulo|Diadema|RuadoLimoeiro Brazil|SaoPaulo|SaoCaetano|RuadasLaranjeiras Brazil|Parana|Curitiba|ComendadorAraujo USA|NewJersey|JerseyCity|WhashingtonBoulervard USA|NewJersey|JerseyCity|RiverCourt</p> </blockquote> <p>Which should bring after some array key implementation, something like this (after apply json_encode call on php):</p> <pre><code>{ "name": "Brazil", "children": [ { "name": "SaoPaulo", "children": [ { "name": "Diadema", "children": [ {"name": "RuadaFe"}, {"name": "RuadoLimoeiro"} ] }, { "name": "SaoCaetano", "children": [ {"name": "RuadasLaranjeiras"} ] }, ] "name": "Parana", "children": [ { "name": "Curitiba", "children": [ {"name": "ComendadorAraujo"} ] } ] }, "name":"USA", "children":[ { "name": "NewJersey", "children": [ { "name": "JerseyCity", "children": [ {"name": "WhashingonBoulevard"}, {"name": "RiverCourt"} ] } ] } ] } ] </code></pre> <p>And keep going and going (and even more deeper too). Please, help me team... thanks in advance.</p> <p>Here what I get until now:</p> <p>Array ( [Brazil] => Array ( [SaoPaulo] => Array ( [Diadema] => Array ( [RuadoLimoeiro] => )</p> <pre><code> [SaoCaetano] =&gt; Array ( [RuadasLaranjeiras] =&gt; ) ) [Parana] =&gt; Array ( [Curitiba] =&gt; Array ( [ComendadorAraujo] =&gt; ) ) ) [USA] =&gt; Array ( [NewJersey] =&gt; Array ( [JerseyCity] =&gt; Array ( [WhashingtonBoulervard] =&gt; [RiverCourt] =&gt; ) ) ) </code></pre> <p>)</p> <p>And here is the json encoded:</p> <pre><code>{ "Brazil":{ "SaoPaulo": {"Diadema": {"RuadoLimoeiro":null}, "SaoCaetano":{"RuadasLaranjeiras":null} }, "Parana": {"Curitiba": {"ComendadorAraujo":null} } }, "USA":{ "NewJersey":{ "JerseyCity":{ "WhashingtonBoulervard":null, "RiverCourt":null} } } } </code></pre> <p>As you can see, the "names" and "child" is missing because is not an array key structure, also something is wrong, because I'm missing some values on SaoPaulo.</p> <p>Here is the function:</p> <pre><code>foreach($strings as $string) { $parts = array_filter(explode('|', $string)); $ref = &amp;$result; foreach($parts as $p) { // echo $p; if(!isset($ref[$p])) { $ref[$p] = array(); // $ref[$p] = array("name"=&gt;$p); } $ref = &amp;$ref[$p]; } $ref = null; } </code></pre> <p>-------------------------------- AFTER SOME ANSWERS --------------------------</p> <pre><code>{ "name": "Brazil(country)", "children": [ { "name": "SaoPaulo(state)", // only one state "children": [ { "name": "Diadema(city)", // only one city "children": [ {"name": "RuadaFe(street)"}, // two streets under the same city... {"name": "RuadoLimoeiro(street)"} ] }, { "name": "SaoCaetano(city)", "children": [ {"name": "RuadasLaranjeiras(street)"} ] }, ] "name": "Parana(state)", "children": [ { "name": "Curitiba(city)", "children": [ {"name": "ComendadorAraujo(street)"} ] } ] },... </code></pre> <p>I put on parentesis the structure (country, state, city, street) just to clarify what i want. Got it?</p>

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.
