using simultaneous arrays

[Ian Davies]

I have a table with each column containing the following form objects -
combobox, hidden field, textarea, and tick box. I have created arrays from
each of these columns and now I wish to use the arrays altogether, taking
each array element in order to use in an sql statement
Does anyone know how to use arrays simultaneously
eg
Array1 - 1,2,3
Array2 - text1,text2,tex t3
Array3 - 31,56,34
Aray4- 1,1,0

used in a loop to populate the following SQLs
SQL="UPDATE mytable SET fieldA=Array2[0], fieldB=Array3[0], fieldC=Array4[0]
WHERE Index=Array1[0]"
SQL="UPDATE mytable SET fieldA=Array2[1], fieldB=Array3[1], fieldC=Array4[1]
WHERE Index=Array1[1]"
etc
for all the elements in the array

Re: using simultaneous arrays

Hi Ian

You could simply use a multidimensiona l array ;)

Like

$AllItems = array();

for($i = 0; $i < 10; ++$i)
{
$TestData = Array($i,$i*2," Foo, ");
array_push($All Items, $TestData );
}

Then you can access your array via $AllItems[ any valid index]

maybe this is what you want

Best regards

<?

for ($i = 0; $i < count($Array1); $i++)
{
$sql = "update mytable
set fieldA = {$Array2[$i]},
fieldB = {$Array3[$i]},
fieldC = {$Array4[$i]},
where Index = {$Array1[$i]}";
mysql_query($sq l);
}

?>
