RE: [PHP] Array vs. Scalar Lists

"ibase_execute( $prep, implode('',$data))" is the same as "ibase_execute ( $prep, $data[0] . $data[1] )" . It's still one value, but now it's concatenated. Here's all of the examples I could think of. They used echo, for simplicity: <? header ( "Content-type: text/plain" ) ; $string1 = 'Hello' ; $dlm = ' ' ; $string2 = 'world' ; $punct = '!' ; $strings = Array ( $string1, $dlm, $string2, $punct ) ; // works as advertised, but it's hard coded echo $string1, $dlm, $string2, $punct ; echo chr(13) ; // same as above echo $strings[0], $strings[1], $strings[2], $strings[3] ; echo chr(13) ; // does not work as above echo $strings ; echo chr(13) ; // here we go, oh guess not echo array_slice ( $strings, 0, count ( $strings ) ) ; echo chr(13) ; // yuck - it's just one long string now echo implode ( '', $strings ) ; echo chr(13) ; // works, but echo issued multiple times foreach ( $strings as $val ) { echo $val ; } echo chr(13) ; // works great, but too complicated $stmt = 'echo ' ; foreach ( $strings as $key => $val ) { if ( next ( $strings ) ) { $stmt .= "\$strings[$key], " ; } else { $stmt .= "\$strings[$key] ;" ; } } eval ( $stmt ) ; ?> Anthony -----Original Message----- From: James Moore [mailto:jmoore@php.net] Sent: Friday, December 01, 2000 12:56 PM To: Anthony Martin; 'Lars Torben Wilson' Cc: php-general@lists.php.net Subject: RE: [PHP] Array vs. Scalar Lists Whats wrong with somthing like ibase_execute( $prep, implode('',$data)); ?

What I'm really trying to do is a little more complicated: $data = Array ( 'c1f2g3h4j5r', 'AC', ) ; $stmt = 'SELECT * FROM PROFILE WHERE SESSION = ? AND STATUS = ? ;' ; $prep = ibase_prepare ( $dbh, $stmt ) ; $result = ibase_execute ( $prep, $data[0], $data[1] ) ; I want to avoid having to pass each value of the array to ibase_execute. I would much rather do: $result = ibase_execute( $prep, $data ) ; But this function wants to see two values. It doesn't take into account that it's been given an array with two values in it. So if I want a programmatic solution, I have to use my eval() insanity (or is that evil insanity like Microsoft's spell check keeps telling me it is).

You're doing an insane amount of work to accomplish pretty much the same thing...and even so, the above would be better written as $stmt = 'echo ' . implode(', ', $arrayofstrings) . ";"; eval($stmt); What added value are you getting from the eval() here? -- +----------------------------------------------------------------+ |Torben Wilson <torben@php.net> Netmill iTech| |http://www.coastnet.com/~torben http://www.netmill.fi| |Ph: 1 250 383-9735 torben@netmill.fi| +----------------------------------------------------------------+ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
