The built-in PHP mysqli_field_tell() function accepts a result object as a parameter, retrieves and returns the current position of the field cursor in the given object.

Parameter Details

Return Value

This built-in PHP function returns an integer value specifying the current position of the field cursor in the given result object.

PHP Version

This PHP function was first introduced in PHP version 5 and works in all the later versions.

Example1

The following below is an example which demonstrates the usage of the built-in PHP mysqli_field_tell() function (in a procedural style) -

<?php
   $con = mysqli_connect("localhost", "root", "password", "mydb");

   mysqli_query($con, "CREATE TABLE myplayers(ID INT, First_Name VARCHAR(255), Last_Name VARCHAR(255), Place_Of_Birth VARCHAR(255), Country VARCHAR(255))");
   print("Table Created.....\n");
   mysqli_query($con, "INSERT INTO myplayers values(1, 'Kennedy', 'Nkpara', 'PortHarcourt', 'Nigeria')");
   mysqli_query($con, "INSERT INTO myplayers values(2, 'Jonathan', 'Trott', 'CapeTown', 'SouthAfrica')");
   mysqli_query($con, "INSERT INTO myplayers values(3, 'Queen', 'Douglas', 'Texas', 'UnitedStates')");
   print("Record Inserted.....\n");

   //Retrieving the contents of the table
   $res = mysqli_query($con, "SELECT * FROM myplayers");

   //Fetching the fields
   while($info = mysqli_fetch_field($res)){
      //Current field
      $currentfield = mysqli_field_tell($res);
      print("Current Field: ".$currentfield."\n");
      print("Name: ".$info->name."\n");
      print("Table: ".$info->table."\n");
      print("Type: ".$info->type."\n");
   }

   //Closing the statement
   mysqli_free_result($res);

   //Closing the connection
   mysqli_close($con);
?>

Output

When the above code is executed, it will produce the following result -

Table Created.....
Record Inserted.....
Current Field: 1
Name: ID
Table: myplayers
Type: 3
Current Field: 2
Name: First_Name
Table: myplayers
Type: 253
Current Field: 3
Name: Last_Name
Table: myplayers
Type: 253
Current Field: 4
Name: Place_Of_Birth
Table: myplayers
Type: 253
Current Field: 5
Name: Country
Table: myplayers
Type: 253

Example2

In an object oriented style the syntax of this function is $result->current_field(); Following is the example of this function in an object oriented style -

<?php
   //Creating a connection
   $con = new mysqli("localhost", "root", "password", "mydb");

   $con -> query("CREATE TABLE Test(Name VARCHAR(255), AGE INT)");
   $con -> query("insert into Test values('Kennedy', 27),('Paul', 30),('Justice', 28)");
   print("Table Created.....\n");

   $stmt = $con -> prepare( "SELECT * FROM Test WHERE Name in(?, ?)");
   $stmt -> bind_param("ss", $name1, $name2);
   $name1 = 'Kennedy';
   $name2 = 'Paul';

   //Executing the statement
   $stmt->execute();

   //Retrieving the result
   $result = $stmt->get_result();

   //Current Field
   $info = $result->fetch_field();

   $field = $result->current_field;
   print("Current Field: ".$field."\n");
   print("Field Name: ".$info->name);

   //Closing the statement
   $stmt->close();

   //Closing the connection
   $con->close();
?>

Output

When the above code is executed, it will produce the following result -

Table Created.....
Current Field: 1
Field Name: Name
