Proposed Function: urlencode_array

proto urlencode_array(array formdata [, string numeric_prefix]) Purpose: Generate a form encoded query string from an associative (or indexed) array. Example: $formdata = array('page'=>'home', 'users'=>array('bob'=>array('fname'=>'Bob','lname'=>'Smith'), 'jdoe'=>array('fname'=>'Jane','lname'=>'Doe')), 'errors'=>array('missing date','missing time','sums not =='), 'other data'); echo urlencode_array($formdata); /* outputs the following page=home&users[bob][fname]=Bob&users[bob][lname]=Smith&users[jdoe][fname]=J ane&users[jdoe][lname]=Doe&errors[0]=missing+date&errors[1]=missing+time&err ors[2]=sums+not+%3D%3D&0=other+data */ Example 2: Same array as above but encoded using a prefix for numeric values: echo urlencode_array($formdata, 'misc_'); page=home&users[bob][fname]=Bob&users[bob][lname]=Smith&users[jdoe][fname]=J ane&users[jdoe][lname]=Doe&errors[0]=missing+date&errors[1]=missing+time&err ors[2]=sums+not+%3D%3D&misc_0=other+data Note Example 2 allows numerically indexed arrays to generate query strings which will yield legal variable names, but doesn't enforce such behavior. Also, the numeric_prefix only applies to the root array's indexes since subsequence arrays may be indexed without compromise. The patch is available at: http://frankenbox.alphaweb.net/test/urlencode_array.diff.txt The underlying function php_url_encode_hash() is meant for later use in http_request() and for handling a context option in the http:// wrapper, but it seems as though there's no harm exporting it to userland. (Hence the addition of urlencode_array() -- I'm flexible on the name, array_urlencode() has been suggested as well) I'm looking for a couple +1s before I actually commit this though. -Sara
