php - Mysqli not showing errors properly -

i trying learn mysqli of functions. 1 thing left have proper error reporting across layers. don't understand why following snippet of code detects error won't error number nor error code.

function get_pid_tid_by_pk($con,$ourid) {     $returned['errno'] ="";     $returned['error'] ="";     //mistake on here!!!     if(!$stmt = $con->prepare("elect gene_name,jgi_protein_id,jgi_transcript_id jgi_transid_protid_match our_protein_id = ?"))     {         $returned['errno'] = $con->errno;         $returned['error'] = $con->error;         return $returned;     }      if(!$stmt->bind_param('s',$ourid))     {         $returned['errno'] = $stmt->errno;         $returned['error'] = $stmt->error;          return $returned;     }      if(!$stmt->execute())     {         $returned['errno'] = $stmt->errno;         $returned['error'] = $stmt->error;          return $returned;     }      $stmt->bind_result($gene_name,$jgi_protein_id,$jgi_transcript_id);     $stmt->fetch();      $fetchedarray['gene_name'] = $gene_name;     $fetchedarray['jgi_protein_id'] = $jgi_protein_id;     $fetchedarray['jgi_transcript_id'] = $jgi_transcript_id;      //have use hack since query returns object , not array , don't want make object oriented if don't know talking ignore comment     $returned['assoc'] = $fetchedarray;      return $returned; } 

the mistake obvious , on 6th line wrote elect instead of select program getting inside block errno , error null. doing wrong.this code works fine if don't break on purpose.

are sure if statement correct?

if(!$stmt = $con->prepare("elect gene_name,jgi_protein_id,jgi_transcript_id jgi_transid_protid_match our_protein_id = ?")) {     $returned['errno'] = $con->errno;     $returned['error'] = $con->error;     return $returned; } 

should be

if(($stmt = $con->prepare("elect gene_name,jgi_protein_id,jgi_transcript_id jgi_transid_protid_match our_protein_id = ?")) === false) {     $returned['errno'] = $con->errno;     $returned['error'] = $con->error;     return $returned; } 

or split assignment

$stmt = $con->prepare("elect gene_name,jgi_protein_id,jgi_transcript_id jgi_transid_protid_match our_protein_id = ?"); if($stmt === false) {     $returned['errno'] = $con->errno;     $returned['error'] = $con->error;     return $returned; }
