note 41948 added to function.serialize

regarding PHP to JS serialization I did some time ago a function which works using "eval" as Harry points out. //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_' */ 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 = $recursed ? "\"$var\"" : "(new String(\"$var\"))"; } elseif (is_bool($var)) { $var = ($var)?'true':'false'; $js = $recursed ? $var : "(new Boolean($var))"; } else { //should be an int or a float in theory $js = $recursed ? $var : "(new Number($var))"; } return $js; } ---- Manual Page -- http://www.php.net/manual/en/function.serialize.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+41948 Delete -- http://master.php.net/manage/user-notes.php?action=delete+41948&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+41948&report=yes Search -- http://master.php.net/manage/user-notes.php
