Re: Finer points of debugging: vardump vs. print_r

Here's some info about the two functions. Descriptions (from manual) : -------------------------------- print_r -- Prints human-readable information about a variable (PHP 4) var_dump -- Dumps information about a variable (PHP 3 >= 3.0.5, PHP 4) An example : -------------------------------- <pre> <?php $example = array ('str' => 'is good', 'letters' => array ('a','b','c'), 'integer' => 31, 'float/double' => 35.3787, 24 => 'hello'); echo 'print_r :'. "\n\n"; print_r ($example); echo 'var_dump :'. "\n\n"; var_dump ($example); ?> </pre> Output (layout altered) : --------------------------------- print_r : Array ( [str] => is good [letters] => Array ( [0] => a [1] => b [2] => c ) [integer] => 31 [float/double] => 35.3787 [24] => hello ) var_dump : array(4) { ["str"] => string(7) "is good" ["letters"] => array(3) { [0] => string(1) "a" [1] => string(1) "b" [2] => string(1) "c" } ["integer"] => int(31) ["float/double"] => float(35.3787) [24] => string(5) "hello" } Manual Entries : -------------------------------- http://www.php.net/manual/en/function.print-r.php http://www.php.net/manual/en/function.var-dump.php Regards, Philip (test: print var dump faq8490) On Tue, 10 Apr 2001, John Lim wrote: > Just a question that has been besetting me for a while: > > which is better for debugging -- vardump( ) or print( ) ? > > Does anyone have a preference?
