Reading a string and passing passing arguments to a while loop

I have an for loop that reads the following file

Code:
cat param.cfg
val1:env1:opt1
val2:env2:opt2
val3:env3:opt3
val4:env4:opt4
.
.

The for loop extracts the each line of the file so that at any one point, the value of i is
Code:
val1:env1:opt1

etc...

I would like to extract each individual attribute and pass it to a while loop as follows:

Code:
for i in $( cat refire.cfg | tail +$START | head -$STOP | grep -v "^#" | grep ':' )
do
# read the value of i here and break it down as arguments x y z for this loop
while read x y z 
do
stuff
done
done

Quote:
The variables $START & $STOP determines the range of execution of the param.cfg file
I want to be able to repeat the while loop for each iteration of i

mysqli_stmt::execute - Executes a prepared Query

       Object oriented style

SYNOPSIS
bool mysqli_stmt::execute (void ) DESCRIPTION
Procedural style bool mysqli_stmt_execute (mysqli_stmt $stmt) Executes a query that has been previously prepared using the mysqli_prepare(3) function. When executed any parameter markers which exist will automatically be replaced with the appropriate data. If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be determined by using the mysqli_stmt_affected_rows(3) function. Likewise, if the query yields a result set the mysqli_stmt_fetch(3) function is used. Note When using mysqli_stmt_execute(3), the mysqli_stmt_fetch(3) function must be used to fetch the data prior to performing any addi- tional queries. PARAMETERS
o $ stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3). RETURN VALUES
Returns TRUE on success or FALSE on failure. 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(); } $mysqli->query("CREATE TABLE myCity LIKE City"); /* Prepare an insert statement */ $query = "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)"; $stmt = $mysqli->prepare($query); $stmt->bind_param("sss", $val1, $val2, $val3); $val1 = 'Stuttgart'; $val2 = 'DEU'; $val3 = 'Baden-Wuerttemberg'; /* Execute the statement */ $stmt->execute(); $val1 = 'Bordeaux'; $val2 = 'FRA'; $val3 = 'Aquitaine'; /* Execute the statement */ $stmt->execute(); /* close statement */ $stmt->close(); /* retrieve all rows from myCity */ $query = "SELECT Name, CountryCode, District FROM myCity"; if ($result = $mysqli->query($query)) { while ($row = $result->fetch_row()) { printf("%s (%s,%s) ", $row[0], $row[1], $row[2]); } /* free result set */ $result->close(); } /* remove table */ $mysqli->query("DROP TABLE myCity"); /* close connection */ $mysqli->close(); ?> Example #2 Procedural style <?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } mysqli_query($link, "CREATE TABLE myCity LIKE City"); /* Prepare an insert statement */ $query = "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)"; $stmt = mysqli_prepare($link, $query); mysqli_stmt_bind_param($stmt, "sss", $val1, $val2, $val3); $val1 = 'Stuttgart'; $val2 = 'DEU'; $val3 = 'Baden-Wuerttemberg'; /* Execute the statement */ mysqli_stmt_execute($stmt); $val1 = 'Bordeaux'; $val2 = 'FRA'; $val3 = 'Aquitaine'; /* Execute the statement */ mysqli_stmt_execute($stmt); /* close statement */ mysqli_stmt_close($stmt); /* retrieve all rows from myCity */ $query = "SELECT Name, CountryCode, District FROM myCity"; if ($result = mysqli_query($link, $query)) { while ($row = mysqli_fetch_row($result)) { printf("%s (%s,%s) ", $row[0], $row[1], $row[2]); } /* free result set */ mysqli_free_result($result); } /* remove table */ mysqli_query($link, "DROP TABLE myCity"); /* close connection */ mysqli_close($link); ?> The above examples will output: Stuttgart (DEU,Baden-Wuerttemberg) Bordeaux (FRA,Aquitaine) SEE ALSO
