regarding PHP to JS serialization I did some time ago a function which works using "eval" as Harry points out. <?php //helper function, returns true if the array is associative function is_assoc_array( $var ) { //false if not an array or empty if ( (!is_array($var)) || (!count($var)) ) return false; foreach($var as $k=>$v) if (! is_int($k)) return true; return false; } ?> Serialize function which generates JavaScript's eval's compatible code. Usage (JavaScript) : var myVar = eval('<?php js_serialize($phpvar); ?>'); Notes: Objects and associative arrays are encoded as JS Objects Doesn't serialize object methods Serializes 'resource' types as nulls Assoc. Arrays containing integer keys, those keys are prefixed with 'idx_' <?php function js_serialize($var, $recursed = false) { if (is_null($var) || is_resource($var)) return 'null'; $js = ''; //object or assoc. array if (is_object($var) || is_assoc_array($var)) { //typecast to array in the case it could be an object $props = (array)$var; foreach($props as $k=>$v) { //index values are preffixed with 'idx_' if (is_int($k)) $k = "idx_$k"; $js .= $k.':'.js_serialize($v, true).','; } if (count($props)) $js = substr($js, 0, strlen($js)-1); $js = '{'.$js.'}'; if (! $recursed) $js = "($js)"; } elseif (is_array($var)) { foreach($var as $v) $js .= js_serialize($v, true).","; if (count($var)) $js = substr($js, 0, strlen($js)-1); $js = "[$js]"; } elseif (is_string($var)) { //escape the string $var = str_replace( array('"', "\n", "\r"), array('\\"', '\\n'), $var ); $js = $recursed ?
