Re: Problems with globals...

Hey Chris: Several problems in the test. The array created just had an enumerated index. Also, the results in the "After" section were looking at the initial variables, not the stuff you stuck into the array and ran through the function. function stringsToLower( $stringsArray ) { while ( list($Key,$Val) = each($stringsArray ) ) { global $$Key; $$Key = strtolower($Val); } } $joe = "This"; $bob = "That"; $briggs = "Other"; echo "Before: $joe $bob $briggs<br>\n"; $Blah = array( "joe"=>"$joe", "bob"=>"$bob", "briggs"=>"$briggs" ); stringsToLower( $Blah ); echo "<p>After: $joe $bob $briggs<br>\n"; Things that are different: * Created associative index on the array. * Switch to while/list/each rather than a count(), far simpler. * "global $$Key;" rather than just "global $Key;" This process seems kind of overblown. I mean, why are you making an array to check this? It'd be much simpler to just run your variables through the strtolower() directly $briggs = strtolower($briggs); rather than having to create an array to then check. Perhaps the incoming info is already in an array? Enjoy, --Dan -- T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y More than just answers. Solutions.
