How do I loop php arrays -
this product array -
array ( [0] => array ( [0] => 'product1' [1] => [2] => [3] => [4] => 'product2' [5] => [6] => [7] => 'product3' [8] => 'product4' [9] => 'product5' ) ) and category array product -
array ( [0] => array ( [0] => 'cat1' [1] => 'cat2' [2] => 'cat3' [3] => 'cat4' [4] => 'cat5' [5] => 'cat6' [6] => 'cat7' [7] => [8] => [9] => ) ) final output require in format -
array ( 'product1' => array( [0] => 'cat1', [1] => 'cat2', [2] => 'cat1', [3] => 'cat4' ), 'product2' => array( [0] => 'cat5', [1] => 'cat6', [2] => 'cat7' ), 'product3' => array( [0] => 'no cat' ), 'product4' => array( [0] => 'no cat' ), 'product5' => array( [0] => 'no cat', ) ) i tried not forming correct output --
$newarr = array(); foreach( $productdata[0] $arr1 ) { if( $arr1 != '' ) { foreach( $catdata[0] $catnames ){ $newarr[$arr1] = array($compnames); } } } echo "<pre>";print_r($newarr);
if count($productdata[0]) == count($catdata[0]) can use loop. if $productdata[0][0] going contain product name should work.
<?php // array return $a = array(); // loop thru array for($i = 0; $i < count($productdata[0]); $i++) { // if product name exists time start new array entry if($productdata[0][$i] != '') { // product name need might need next iteration $current = $productdata[0][$i]; // create new array $a[$current] = array(); if($catdata[0][$i] != '') { // , save category @ iteration new array $a[$current][] = $catdata[0][$i]; } else { $a[$current][] = 'no cat'; } } else { // product name blank, , $current should set, append category. $a[$current][] = $catdata[0][$i]; } } echo "<pre>"; print_r($a); echo "</pre>";
