hello;
this works:
Code: Select all
<?php
for ($i = 0 ; $i < count($item_array) ; $i++)
{ $item_parsed_array = explode("=" , $item_array[$i]);
print("$item_parsed_array[0]<br>$item_parsed_array[1]<p>");
?>
however this does not:
Code: Select all
<?php
for ($i = 0 ; $i < count($item_array) ; $i++)
{ $item_parsed_array[$i] = explode("=" , $item_array[$i]);
print("$item_parsed_array[$i][0]<br>$item_parsed_array[$i][1]<p>");
?>
my conclusion is that I cannot index an array with a variable; any thoughts?
thank you

It is totally possible to use variables as array indexs.
Have you tried useing foreach()?
Code: Select all
<?php
foreach( $item_array as $key => $value )
{
$item_parsed_array[$key] = explode('=', $value);
}
print_r( $item_parsed_array );
?>

hello sevengraff; thanks for the response;
I have not tried any other loops; however I have finally gotten the solution; the problem is have a variable index WITHIN a print statement;
Solution: curly brackets;
Code: Select all
<?php
for ($i = 0 ; $i < count($item_array) ; $i++)
{ $item_parsed_array[$i] = explode("=" , $item_array[$i]);
print("{$item_parsed_array[$i][0]}<br>{$item_parsed_array[$i][1]}<p>");
}
?>
thanks
Shannon

Formatting your code and removing uneccessary characters (such as parenthesis around print() statements), can make things somewhat easier to debug:
Code: Select all
<?php
for ($i = 0 ; $i < count($item_array) ; $i++)
{
$item_parsed_array[$i] = explode("=" , $item_array[$i]);
print "{$item_parsed_array[$i][0]}<br>{$item_parsed_array[$i][1]}<p>";
}
?>
If you are using a syntax highlighter, you can make the variables stand out by using concenation:
Code: Select all
print $item_parsed_array[$i][0].'<br />'.$item_parsed_array[$i][1].'<p>';
