php - Change my array dynamically -
i have function returns array this:
[ "var0 => 300 pr. d. joÃo", "var1 =>a passar", "var2 =>", "var3 => 904 q.bela vista", "var4 =>a passar", "var5 =>", "var6 => 905 monte virgem", "var7 =>a passar", "var8 =>", "var9 => 300 telheira - c", "var10 =>a passar", "var11 =>", "var12 => 200 cast. queijo", "var13 =>20:39", "var14 =>5min" ] and need result next example: it's necessary in format.
[ "route" => "300 pr. d. joÃo", "eta" =>"a passar", "waittime" =>"", "route" => "904 q.bela vista", "eta" =>"a passar", "waittime" =>"", "route" =>" 905 monte virgem", "eta" =>"a passar", "waittime" =>"", "route" =>" 300 telheira - c", "eta" =>"a passar", "waittime" =>"", "route" =>" 200 cast. queijo", "eta" =>"20:39", "waittime" =>"5min" ] and webservice php code is:
function getpage ($codigo) { $link = "http://www.stcp.pt/pt//itinerarium/soapclient.php?codigo="; $dom = new domdocument(); $homepage = file_get_contents($link.$codigo); $dom->loadhtml($homepage); $tables = $dom->getelementsbytagname('table'); $table = $tables->item(0); $i = 0; $var = array(); foreach ($table->childnodes $tr) { if ($tr->nodename == 'tr') { foreach ($tr->childnodes $td) { $i++; $tds= $td->nodevalue; if ($i%2 == 0) { } else { array_push($var, $tds); } } } else { echo "string "; } } $first = array_shift($var); $second = array_shift($var); $third = array_shift($var); $maxvar = sizeof($var); $final_array = array(); ($k=0; $k < sizeof($var); $k++) { ${'var' . $k} = $var[$k]; array_push($final_array, "var$k =>".$var[$k]); } echo json_encode($final_array); } how can return json example show?
because associative arrays must have unique keys, cannot have route, eta, or waittime appearing more once in output. can create nested array represents data quite nicely.
$a = [ "var0 => 300 pr. d. joÃo", "var1 =>a passar", "var2 =>", "var3 => 904 q.bela vista", "var4 =>a passar", "var5 =>", "var6 => 905 monte virgem", "var7 =>a passar", "var8 =>", "var9 => 300 telheira - c", "var10 =>a passar", "var11 =>", "var12 => 200 cast. queijo", "var13 =>20:39", "var14 =>5min" ]; function removevarprefix($x) { return preg_replace('/^var\d+\s*=>\s*/', '', $x); } $b = array_map(function($set) { list($route, $eta, $waittime) = array_map('removevarprefix', $set); return ['route'=>$route, 'eta'=>$eta, 'waittime'=>$waittime]; }, array_chunk($a, 3)); echo json_encode($b, json_pretty_print); output (updated show json)
[ { "route": "300 pr. d. jo\u00c3o", "eta": "a passar", "waittime": "" }, { "route": "904 q.bela vista", "eta": "a passar", "waittime": "" }, { "route": "905 monte virgem", "eta": "a passar", "waittime": "" }, { "route": "300 telheira - c", "eta": "a passar", "waittime": "" }, { "route": "200 cast. queijo", "eta": "20:39", "waittime": "5min" } ]
