    <p>This is the first time i ever face, that var_dumping json_encode of an array resulting boolean value.</p> <p>I have an array that was resulted from unserialization. I var_dumped it and made sure that it is a valid array. The result is like below. This is just a piece, not entire debug view.</p> <pre><code>array (size=3) 'id' =&gt; string 'asco-power-technologies-l-p' (length=27) 'name' =&gt; string 'asco-power-technologies-l-p' (length=27) 'children' =&gt; array (size=2) 0 =&gt; array (size=4) 'id' =&gt; string 'apl-logistics' (length=13) 'name' =&gt; string 'APL LOGISTICS' (length=13) 'data' =&gt; array (size=2) 'band' =&gt; string 'ASCO POWER TECHNOLOGIES ,L.P.' (length=29) 'relation' =&gt; string 'Buyer of band' (length=13) 'children' =&gt; array (size=11) 0 =&gt; &amp; array (size=3) 'id' =&gt; string 'trisa-ag' (length=8) 'name' =&gt; string 'TRISA AG' (length=8) 'data' =&gt; array (size=2) 'band' =&gt; string 'APL LOGISTICS' (length=13) 'relation' =&gt; string 'Buyer of band' (length=13) 1 =&gt; &amp; array (size=3) 'id' =&gt; string 'colgate-sanxiao-co-ltd' (length=22) 'name' =&gt; string 'COLGATE SANXIAO CO LTD' (length=22) 'data' =&gt; array (size=2) 'band' =&gt; string 'APL LOGISTICS' (length=13) 'relation' =&gt; string 'Buyer of band' (length=13) </code></pre> <p>.....</p> <p>Aterwards i json_encode it with max depth=3. Note, i am using PHP 5.5 and running on Apache 2.4, so that it supports depth parameter on json_encode(). This is what i was doing.</p> <pre><code> $array = unserialize($serial); var_dump($array); $json = json_encode($array, JSON_PRETTY_PRINT, 3); var_dump($json); </code></pre> <p>Finally i got <code>$array</code> var_dumped properly and <code>$json</code> var_dumped with result of false boolean value. What's wrong with it? Is it due to early PHP release that unproper var_dump would result false boolean? Have anyone ever faced this?</p> <p><strong>UPDATE:</strong></p> <p>This is the serialize string. The entire string is too bunch so i paste only a piece.</p> <pre><code>a:3:{s:2:"id";s:27:"asco-power-technologies-l-p";s:4:"name";s:27:"asco-power-technologies-l-p";s:8:"children";a:2:{i:0;a:4:{s:2:"id";s:13:"apl-logistics";s:4:"name";s:13:"APL LOGISTICS";s:4:"data";a:2:{s:4:"band";s:29:"ASCO POWER TECHNOLOGIES ,L.P.";s:8:"relation";s:13:"Buyer of band";}s:8:"children";a:11:{i:0;a:3:{s:2:"id";s:8:"trisa-ag";s:4:"name";s:8:"TRISA AG";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:1;a:3:{s:2:"id";s:22:"colgate-sanxiao-co-ltd";s:4:"name";s:22:"COLGATE SANXIAO CO LTD";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:2;a:3:{s:2:"id";s:25:"apll-on-behalf-oftongfang";s:4:"name";s:25:"APLL ON BEHALF OFTONGFANG";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:3;a:3:{s:2:"id";s:26:"apll-on-behalf-of-zhejiang";s:4:"name";s:26:"APLL ON BEHALF OF ZHEJIANG";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:4;a:3:{s:2:"id";s:33:"apll-on-behalf-of-tongfang-global";s:4:"name";s:33:"APLL ON BEHALF OF TONGFANG GLOBAL";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:5;a:3:{s:2:"id";s:34:"apll-on-behalf-of-ningbo-xiangyuan";s:4:"name";s:34:"APLL ON BEHALF OF NINGBO XIANGYUAN";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:6;a:3:{s:2:"id";s:33:"apll-on-behalf-of-ningbo-homestar";s:4:"name";s:33:"APLL ON BEHALF OF NINGBO HOMESTAR";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:7;a:3:{s:2:"id";s:17:"apll-on-behalf-of";s:4:"name";s:17:"APLL ON BEHALF OF";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:8;a:3:{s:2:"id";s:21:"apl-logistics-sdn-bhd";s:4:"name";s:21:"APL LOGISTICS SDN BHD";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}}i:9;a:4:{s:2:"id";s:21:"apl-logistics-limited";s:4:"name";s:21:"APL LOGISTICS LIMITED";s:4:"data";a:2:{s:4:"band";s:13:"APL LOGISTICS";s:8:"relation";s:13:"Buyer of band";}s:8:"children";a:27:{i:0;a:3:{s:2:"id";s:26:"tri-phil-international-inc";s:4:"name";s:27:"TRI-PHIL INTERNATIONAL INC.";s:4:"data";a:2:{s:4:"band";s:21:"APL LOGISTICS LIMITED";s:8:"relation";s:13:"Buyer of band";}}i:1;a:3:{s:2:"id";s:16:"pt-apl-logistics";s:4:"name";s:17:"PT.

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.
