Array Walk Parameter Problem

[Anon]

Hi -

I am trying to apply a function to every member of an array.

I am using:

ARRAY

$colours = array(
"green",
"red",
"blue",
"orange",
"yellow");

CALL TO ARRAY_WALK

@array_walk($colours,myfunction($country,$origin,$weight,$price),$data);

FUNCTION

function myfunction ($value,$key,$data,$country,$origin,$weight,$price) {

$shipped = "<b>shipped</b>";
$notshipped = "<b>not shipped</b>";

if (strstr($data,$value)) {
$resulthtml = "$shipped";
}

else {
$resulthtml = "$notshipped";	
    } 
echo ("$resulthtml");
}

######################

The array_walk function uses the array ($colours) and the function (myfunction) and parses $data which is some free text into the function (myfunction) as the third parameter, as it is placed at the end of the array walk syntax.
The problem that I have is that when I search $data for each of the strings which are members of the array $fruits, the $value doesn't seem to be returned and hence evaluated in the strstr part of the function.

Is this because the array_walk function only allows one additional parameter to be parsed into the user defined function ? or is there perhaps another more simple way of searching some free text for the string values of an array ?

Since foreach() is so easy to use, you can always use it as an alternative:

foreach ($array as $key => $value )
&nbsp;&nbsp;{
&nbsp;&nbsp;function( $key, $array, $lots, $of, $other, $parms, $here );
&nbsp;&nbsp;}

Yeah, just keep in mind that this does not ever allow you to change tthe original array element values.

Actually, it's not too hard: just pass the original array to the function by reference, and use the key to access the original element. QED.
