I have a form that is posting 4 arrays that I need to combine and eventually compose to email. The four arrays:
$quantityArray = $this->input->post('qty');
$dimensionArray = $this->input->post('dimension');
$thicknessArray = $this->input->post('thickness');
$descriptionArray = $this->input->post('description');
will all have the same array length and each index will be related. How do I combine the 4 arrays such as
[0]
'qty' => '1',
'dimenesion => '2x2',
'thickness' => '2in',
'description' => 'this is the description'
[1]
'qty' => '1',
'dimenesion => '2x2',
'thickness' => '2in',
'description' => 'this is the description'
I have tried array_combined, array_merged and can't get the results that I am looking for. Thanks for the help on this.
If you have same length for those arrays here is example code:
$resultArray = array();
foreach($quantityArray as $index => $qty) {
$resultArray[$index]['qty'] = $qty;
$resultArray[$index]['dimenesion'] = $dimensionArray[$index];
$resultArray[$index]['thickness'] = $thicknessArray[$index];
$resultArray[$index]['description'] = $descriptionArray [$index];
}
print_r($resultArray);
This also may work:
<?php
//...
$quantityArray = $this->input->post('qty');
$dimensionArray = $this->input->post('dimension');
$thicknessArray = $this->input->post('thickness');
$descriptionArray = $this->input->post('description');
//
// combine them:
//
$combined = array();
$n = count($quantityArray);
for($i = 0; $i < $n; $i++)
{
$combined[] = array(
'qty' => $quantityArray[$i],
'dimenesion' => $dimensionArray[$i],
'thickness' => $thicknessArray[$i],
'description' => $descriptionArray[$i]
);
}
//
echo "<pre>";
print_r($combined);
echo "</pre>";
?>
If we assume that we have same length for those arrays here is my codes:
$quantityArray = array(1, 1, 5, 3);
$dimensionArray = array("2x2", "3x3", "4x4", "2x2");
$thicknessArray = array("2in", "3in", "4in", "2in");
$descriptionArray = array("this is the description 1", "this is the description 2 ", "this is the description3 ", "this is the description4" );
$myCombinArray = array();
foreach ( $quantityArray as $idx => $val ) {
$subArray = array (
'qty' => $quantityArray [$idx],
'dimenesion' => $dimensionArray [$idx],
'thickness' => $thicknessArray [$idx],
'description' => $descriptionArray [$idx]
);
array_push ( $myCombinArray, $subArray );
}
print_r($myCombinArray);
How about an easy way if there are always those 4 arrays:
$quantityArray = $this->input->post('qty');
$dimensionArray = $this->input->post('dimension');
$thicknessArray = $this->input->post('thickness');
$descriptionArray = $this->input->post('description');
$combinedArray = [$quantityArray, $dimensionArray, $thicknessArray, $descriptionArray];
# old syntax:
# $combinedArray = array($quantityArray, $dimensionArray, $thicknessArray, $descriptionArray);
