now first i've searched signer keyword code

if(stripos($eachitem['description'], "signer") !== false){}

and i'm searching values in description keys.

foreach($items $index => $eachitem) {    if(stripos($eachitem['description'], "signer") !== false) {       if($eachitem['description'] == "signer") {           $current = $eachitem['description'];                       $keys = array_keys($eachitem);                       $ordinal = (array_search($current,$keys)+1)%count($keys);                       $next = $keys[$ordinal];       }    } }

now want description key of each index example @ index 1 description signer , @ index 2 description - sign , @ index 3 description 1 want description value of each index when concatenate description key value signer-1 in code next key boundingpoly of same index want description keys of each index.

you can this. output this: array('singer-1', 'singer-2', ...)

$visited = -1; $output = [];  foreach($items $index => $item) {    if($item['description'] == 'singer')   {       $output[$visited+1] = 'singer';       $visited++;   }   else   {       $output[$visited] .= $item['description'];   }  }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
