create array from multiple arrays & submit in mysql table - php

Question

I am trying to fetch values from few - dynamically created HTML FORM & in action file, i am grabbing those values via $_POST. Please consider humbly, that i am using array in dynamic inputs like :
<input name="array1[]" />
<input name="array2[]" />
<input name="array3[]" />
So, that, after FORM SUBMIT, in action file, its giving :
$a = Array
(
[0] => 04/21/2017
[1] => 04/19/2017
[2] => 04/25/2017
[3] => 04/25/2017
[4] => 10/25/2017
)
$b= Array
(
[0] => 11
[1] => 34
[2] => 12
[3] => 12
[4] => 2
)
$c= Array
(
[0] => fghgthg
[1] => ggfg
[2] => fgfgfdgf
[3] => fgfdgdgfgdh
[4] => rgrgfgf
)
Now, m having troubles in arranging this way :
$FinalArray = array(
array($a[0], $b[0], $c[0]),
array($a[1], $b[1], $c[1]),
array($a[2], $b[2], $c[2]),
array($a[3], $b[3], $c[3]),
......last line without comma
);
And submitting in mysql table, so that i can easily retrieve it like :
step-1 : $FinalArray[0];
step-2 : $FinalArray[1];
.......goes on
Thanks, for help, in Advance.

This simple foreach help you in achieving your desired output.
Try this code snippet here
<?php
ini_set('display_errors', 1);
$a = Array
(
0 => "04/21/2017",
1 => "04/19/2017",
2 => "04/25/2017",
3 => '04/25/2017',
4 => "10/25/2017"
);
$b = Array
(
0 => 11,
1 => 34,
2 => 12,
3 => 12,
4 => 2
);
$c = Array
(
0 => "fghgthg",
1 => "ggfg",
2 => "fgfgfdgf",
3 => "fgfdgdgfgdh",
4 => "rgrgfgf",
);
$result=array();
foreach($a as $key => $value)
{
$result[]=array($value,$b[$key],$c[$key]);
}
print_r($result);
Output:
Array
(
[0] => Array
(
[0] => 04/21/2017
[1] => 11
[2] => fghgthg
)
[1] => Array
(
[0] => 04/19/2017
[1] => 34
[2] => ggfg
)
[2] => Array
(
[0] => 04/25/2017
[1] => 12
[2] => fgfgfdgf
)
[3] => Array
(
[0] => 04/25/2017
[1] => 12
[2] => fgfdgdgfgdh
)
[4] => Array
(
[0] => 10/25/2017
[1] => 2
[2] => rgrgfgf
)
)
