Note Submitter: g4wx3 ---- I needed a function to convert a php array into a javascript array. No problem i found it on "the net". But the function i found wasn't good enough, instead of return a string with javascript-array it echoed directly everything. I wanted to write the string to a file, when calling the function out of my function libary. Secondly, there where minor "bugs" in the script, when you're original array contained characters like line breaks(\r\n,..), or quotes('), it would hack up the javascript array Sow, i changed the function and fixed the bug. <?php //SUPER COOL : http://www.communitymx.com/content/article.cfm?page=3&cid=7CD16 //Checkout: REVERSE: http://www.hscripts.com/tutorials/php/jsArrayToPHP.php //Convert a PHP array to a JavaScript one (rev. 4) //Changlog by g4wx3: echo replaced by $output, added function output function output($string) //make javascript ready { $string = str_replace( array( '\\' , '\'' ), array('\\\\', '\\\'') , $string); //-> for javascript array $string = str_replace( array("\r\n", "\r", "\n") , '<br>' , $string); //nl2br return $string; } function arrayToJS4($array, $baseName ) { //Write out the initial array definition //v4 echo ($baseName .

"]"; } else { //A string key, so output as a string $outKey = "['" . $key . "']"; } if (is_array($value)) { //The value is another array, so simply call //another instance of this function to handle it $output .= arrayToJS4($value, $baseName . $outKey); } else { //Output the key declaration //v4 echo ($baseName . $outKey . " = "); $output .= $baseName . $outKey . " = "; //Now output the value if (is_string($value)) { //Output as a string, as we did before //v4 echo ("'" . output($value) . "'; \r\n "); $output .= "'" . output($value) . "'; \r\n "; } else if ($value === false) { //Explicitly output false //v4 echo ("false; \r\n"); $output .= "false; \r\n"; } else if ($value === NULL) { //Explicitly output null //v4 echo ("null; \r\n"); $output .= "null; \r\n"; } else if ($value === true) { //Explicitly output true //v4 echo ("true; \r\n"); $output .= "true; \r\n"; } else { //Output the value directly otherwise //v4 echo ($value . "; \r\n"); $output .= $value . "; \r\n"; } } } return $output; } ?> You can use this for printing $_GET array, for example
