    <p>I have a php script that sorts 2 multi-dimensional arrays. Now if i use plain array_multisort it jumbles the 2 arrays for certain rows because both arrays have some tricky elements</p> <p>eg: a[2][2]='35' and b[2][2]='0035'</p> <p>also, a[3][4]='+0.03' b[3][4]='+.03'</p> <p>a[4][6]='31-12-2012' b[4][6]='12/31/2012'</p> <p>Because of the above tricky element difference sorting of both arrays gives different result. I need them to sort appropriately because my req are to do one-to-match across each row for analysis purposes.</p> <p>Please suggest how do I go ahead to 'smart' sort these arrays to give same result</p> <p>i have tried something on the lines of</p> <pre><code> function sort2dArray($data) { $tmp = array(); $lineCount = count($data); foreach ($data as $lineNum =&gt; $lineData) { foreach ($lineData as $column =&gt; $value) { $tmp[$column][$lineNum] = standardize($value); } } $multiSortArgs = array(); foreach ($tmp as $column =&gt; $columnData) { array_push($multiSortArgs, $columnData, SORT_ASC); } $multiSortArgs[] = &amp;$data; call_user_func_array('array_multisort', $multiSortArgs); return $data; } function standardize($value) { if(is_numeric($value)) $pval= $value + 0; else $pval= $value; return $pval; } </code></pre> <p><strong>UPDATE: o/p from both arrays with ',' as delimiter...only considering the 0035 and 35 case</strong></p> <pre><code> BA2063,,,110Y,EFW BA2063,,,110Y,EFW BA2063,,,110Y,EFW BA2063,,,121H,ECD BA2063,,,121H,ECD BA2063,,,121H,ECD BA2063,,,0035,ESW BA2063,,,0035,EFW BA2063,,,0035,EFW BA2063,,,0035,EFW BA2063,,,1L9M,EFW BA2063,,,1L9M,EFW BA2063,,,35,ESW BA2063,,,35,EFW BA2063,,,35,EFW BA2063,,,35,EFW BA2063,,,110Y,EFW BA2063,,,110Y,EFW BA2063,,,110Y,EFW BA2063,,,121H,ECD BA2063,,,121H,ECD BA2063,,,121H,ECD </code></pre>

    1. COcan you display the result of both array's using var dump so we get a brief idea

    2. COit sounds like your input data source is really low quality. a well managed system shouldn't be giving you data in mixed formats in the first place (particularly not mixed date formats -- that's asking for trouble given the potential ambiguities you can have with dates)

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.
