[PHP] Newbie Question: Array Comparison ---
This is a simple question, but I'm having trouble figuring out a solution. Let's say I have 2 arrays: $DoNotPrint=array(a,b,c); $Foo=array(c,d,e): What is the best way to print every value in $Foo that does NOT match a value in $DoNotPrint? For instance, in this example, c should not be print. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

I don't quite understand what you're saying. I'm really sorry. Could you show me some code? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Original problem:
This is a simple question, but I'm having trouble figuring out a
solution.
Let's say I have 2 arrays:
$DoNotPrint=array(a,b,c);
$Foo=array(c,d,e):
What is the best way to print every value in $Foo that does NOT match a
value in $DoNotPrint? For instance, in this example, c should not be
print.
in_array might be one tool - loop through $Foo and print $Foo[n] if it's
not in the array $donotprint
foreach($Foo as $val) {
if(!in_array($val,$DoNotPrint) {
echo $val;
}
}
Any syntax errors you find in that you can keep :-)
And doubtless there are other, better ways. Offers, anyone?
