comparing a value to all of array

[cmoore67]

How do I ask if a variable is equivalent to any member of an array? Seems like something like IMPLODE should work.

example:

if ($id == $id_cat1[0], $id_cat1[1] ETC. ){
$checked="checked";
}else{
$checked="";
}

thanks

Using a for loop is a solution:
//=================
$checked = 0;

for ($i = 0; $i<=$id_cat1.count()-1; $i++)
{
if ($id == $id_cat1[$i])
{
$checked++;
}
}

//the variable $checked is equivalent to the number of values in the array equal to $id.

If you are using PHP4 ypu can use in_array() function
like this
(From the manual )

$os = array ("Mac", "NT", "Irix", "Linux");

if (in_array ("Irix", $os))
print "Got Irix";
