Question

explode on empty string returns array count as 1.

   $consName =explode("|",$docDet['doc_cons_filename']); 
   count($consName);

If there is some value in $docDet['doc_cons_filename'] like ab|cd|de then count($consName) returns 3.

But its returning 1 if $docDet['doc_cons_filename'] has empty value.

is it possible to return count as 0 if we perform count(explode("|",$docDet['doc_cons_filename'])) where $docDet['doc_cons_filename'] = ""

Can anyone help me with solution?

Answer 1

$arr = array();
$str = "yes you are!";
if($i = substr_count($str,"|"))
  $arr = explode("|", $str, $i+1);
echo count($arr);
