How to move the pointer in an array?

[Anon]

Here is a piece of coding:

<?php
echo " <form method=post action='array_push.php'>";
if ($flag1=='')
{
$flag1=0;
}
if ($flag1!='')
{
$flag1=$flag1+1;
}
for ($j=0;$j<=$flag1;$j++)
{
$q=array();
$w="cmbmaillocid"."$j";
array_push($q,$w);
}
while (list($key,$value)=each($q))
{
echo "$key : $value<br>";
}
echo
"<input type=text name=flag1 value='$flag1'>
<input type=submit name=submit value='Submit'></form>";
?>

The problem is values are over written at index 0 itself. I am not able to move the pointer to the next index.

You are allocating the array inside the loop, with the result that you overwrite each previous definition of $q with a new, empty one. You need to
move the array() line before the loop.

Just to show you some variations in style which i prefer

<?php
echo " <form method=post action='array_push.php'>";

could be written as

<form method=post action='array_push.php'>
<?php

if ($flag1=='')
{
$flag1=0;
}
if ($flag1!='')
{
$flag1=$flag1+1;
}

as..

if ($flag1=='')
{
$flag1=0;

} else {
$flag1++;
}

while (list($key,$value)=each($q))
{
echo "$key : $value<br>";
}

as..

while (list($key,$value)=each($q))
{ ?> $key : $value<br> <?
}

I have never used array_push is that a new PHP4 function ?

kind regards
