So I created two shell variables: COLUMN1_HEADING, COLUMN2_HEADING.
They have values:
COLUMN1_HEADING="John"
COLUMN2_HEADING="123456789"
How would I use printf to get it to print an output like this: $COLUMN1_HEADING\t$COLUMN2_HEADING\nJohn\t123456789\n
Thanks! (3 Replies)

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = $mysqli->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
/* get fieldpointer offset */
$currentfield = $result->current_field;
printf("Column %d:
", $currentfield);
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
}
$result->close();
}
/* close connection */
$mysqli->close();

", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = mysqli_query($link, $query)) {
/* Get field information for all fields */
while ($finfo = mysqli_fetch_field($result)) {
/* get fieldpointer offset */
$currentfield = mysqli_field_tell($result);
printf("Column %d:
", $currentfield);
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
