I noticed that your are passing 3 arguments for match function which is wrong!
That is incorrect. Check manual page for gawk.
@OP:
Check this:
Code:
gawk 'BEGIN{
field1="Sdddddfffffggggg"
split(field1,array,"")
print "Pattern : [" array[1] "]"
print "Field 1 :[" field1 "]"
sub(array[1],"",field1)
print "Field 1 after substitution: [" field1 "]" }'
Pattern : [S]
Field 1 :[Sdddddfffffggggg]
Field 1 after substitution: [dddddfffffggggg]
Do you get it? If no, check the explanation of match function in gawk's man page (specifically the manner in which the 3rd argument (array) is populated).

mysqli_fetch_lengths(3) is valid only for the current row of the result set. It returns FALSE if you call it before calling
mysqli_fetch_row/array/object or after retrieving all rows in the result.
EXAMPLES
Example #1
Object oriented style
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$query = "SELECT * from Country ORDER BY Code LIMIT 1";
if ($result = $mysqli->query($query)) {
$row = $result->fetch_row();
/* display column lengths */
foreach ($result->lengths as $i => $val) {
printf("Field %2d has Length %2d
", $i+1, $val);
}
$result->close();
}
/* close connection */
$mysqli->close();
?>
Example #2
Procedural style
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s

exit();
}
$query = "SELECT * from Country ORDER BY Code LIMIT 1";
if ($result = mysqli_query($link, $query)) {
$row = mysqli_fetch_row($result);
/* display column lengths */
foreach (mysqli_fetch_lengths($result) as $i => $val) {
printf("Field %2d has Length %2d
", $i+1, $val);
}
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>
