I am creating an array from several text boxes. I am needing to move the elements in the array to insert into the database. Here is the array:
array(2) { [0]=> string(7) "nameone" [1]=> string(7) "nametwo" }
array(2) { [0]=> string(6) "ageone" [1]=> string(6) "agetwo" }
array(2) { [0]=> string(13) "parentnameone" [1]=> string(13) "parentnametwo" }
array(2) { [0]=> string(14) "parentemailone" [1]=> string(14) "parentemailtwo" }
array(2) { [0]=> string(14) "parentphoneone" [1]=> string(14) "parentphonetwo" }
I want to end up with an insert statement such as:
nameone, ageone, parentnameone, parentemailone, parentphoneone
and next row to insert would be
nametwo, agetwo, parentnametwo, parentemailtwo, parentphonetwo
I have tried to create an array with multiple for each loops but I end up with an array that i need to move the keys which brings be back to my original problem.
Is there a method to this madnaess?

Answer 1

Well, lets say your main array contains 5 arrays with 2 elements each. Lets call that $mainArr. "2" in the first line is no. of elements in each subarray. or if the subarraays are not of equal lengths, then the its the length of the largest subarray.
for($i=0;$i<2;$i++) {
foreach($mainArr as $key => $a) {
$ins[$i][] = $a[$i];
} // form an array with insert elements
}
// traverse that to form inserts
foreach($ins as $key => $arr) {
$statements[] = implode(",", $ins[$key]);
}
echo '<pre>';
print_r($statements);
I think thats what you want. If not, let me know. Hope that helps!

Answer 2

$l = count($array[0]);
for ($i=0; $i<$l; $i++) {
// access values like this:
$name = $array[0][$i]; // equals nameone first time and nametwo second time
$age = $array[1][$i];
$parentname = $array[2][$i];
$parentemail = $array[3][$i];
$parentphone = $array[3][$i];
// insert into DB here
}

Answer 3

#!/usr/bin/php
<?php
$val = array('name', 'age', 'parentname', 'parentemail');
$key = array('one', 'two', 'three', 'four', 'five');
$valone = array();
foreach ($val as $k)
array_push($valone, $k.$key[0]);
var_dump($valone);
?>
Outputs :
array(4) {
[0]=>
string(7) "nameone"
[1]=>
string(6) "ageone"
[2]=>
string(13) "parentnameone"
[3]=>
string(14) "parentemailone"
}
Is this what you want you to do ?
