Re: Proposed Function: urlencode_array

I all my time coding PHP I have yet to encounter where such a function would be useful. It most cases, it would be simpler to generate the final data rather then 2 source arrays, which then will be used to generate the final query string. The one possible issue that I see is people using urlencode_array($_GET) and forgetting about things like magic_quotes_gpc resulting in data corruption etc... Many people also do quite a bit of input validation and usually re-use the same code to build the query string for subsequent pages. -0.5 Ilia On August 28, 2003 05:16 pm, Sara Golemon wrote: > 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&er >r 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&er >r 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.
