I am trying to extract a value from an array if it exists in the array but i always get null even when I know the value does exist
this works
$data['key']
this doesn't work. getVal1 returns null
$sql2="INSERT INTO test (text, date) VALUES ('".getVal1('key',$data)."', NOW())";
function getVal1($name,$d){
if ($d !=null && in_array($name, $d) ) {
return $d[$name];
}
return null;
}
Is there something wrong in my getVal1()
function?
Your problem is in_array
searches for array values, yet you are passing it an array key.
You code can be simplified with isset and ternary if:
function getVal1($name,$d){
return isset($d[$name])?$d[$name]:null;
}
You want:
if (isset($d[$name]))
return $d[$name];
else
return null;
