Try it out this way. I had to change your key names to get my for loop to work.
Code: Select all
$arrFruits = array("m1" => "orange", "m2" => "banana", "m3" => "apple");
/*while ( $element = each($arrFruits) )
{
echo $elementї'1']."<br>";
# Alternatively use
//echo $elementї'value']."<br>";
} */
$number = count($arrFruits);
for($i=0;$i<$number;$i++){
$element = "m".$i;
echo $arrFruitsї$element]."<br>";
}

pelegk2 does your array strictly go up in terms of a,c,c,d,e,f,g..... or are the key name somewhat random?
Build a new array which maps a=>1, b=>2, c=>3 etc and then use that to decide the key name to use when looping
EDIT: You'll need to reverse those key names actually... so 1=>a, 2=>b etc

Code: Select all
$keys = array_keys($array);
$values = array_values($array);
for( $x = 0, $y = count($keys); $x < $y; $x++ )
{
echo $keysї$x];
echo $valuesї$x];
echo $arrayї$keysї$x]];
}
please think.

array_walk()
same source:
foreach()
list()
Very good resource that.
