Associative arrays always getting numeric subscript?

steward

I have been coding FOREACH($ARRAY AS $KEY=>$VAL) for years.

Now with php 5, I find that this iterates through both the numeric subscripts and the associated names. I am confused. Did this change in php 5 or have I lost all my grey cells?

When I iterate an assoc array now I get eg:

5 = five
number = five
6 = foo
fie = foo
7 = fred
name = fred
etc

... so I end up filtering, eg:

foreach($vid AS $fldName => $fldValue)
{
  if ( is_int($fldName) )
  {
    //skip
  }
  else
  {
    process($fldName,$fldValue);
  }
}

Thank you in advance for kind assistance.

If it doesn't do it for you anymore, perhaps you could mention your php version, or what you did to address the issue? Thank you.

Post the smallest and simplest example script that demonstrates the problem. For example, this works for me on PHP 5.2.6:

<?php

$array = array('a' => 'x', 'b' => 'y', 'c' => 'z');

foreach ($array as $key => $value) {
    echo $key . ':' . $value . "<br />\n";
}

?>

I get the output:

a:x
b:y
c:z

What output do you get when you run my example?

This sounds like a mysql_fetch_array() issue, it defaults to both, not just MYSQL_NUM

Which is precisely why I've never used that function... not when there's [man]mysql_fetch_assoc/man! :p

Aye, and I cannot understand why PDOStatement::fetch() defaults to PDO::FETCH_BOTH. They had the chance to settle on one of the two options, but ended up picking a default that makes the two options redundant, and yet is redundant by itself since you only need one of the two options at any one time.
