Using transactions in PHP and MySQL - php

Question

I'm a learner of PHP. This commit and rollback process does the task at each line. How can I commit and rollback all at once?
<?php
$con = mysql_connect('localhost','user', 'abcdefg');
if(!con)
{
echo "Can't connect to db.";
}else {
mysql_select_db('test');
}
if(!file_exits('test.csv')
{
echo "Can't find the file.";
}
$ar_1 = file('test.csv', FILE_IGNORE_NEW_LINES);
foreach ($ar_1 as $ar1)
{
$test = explode(",", $ar1);
$sql = "SELECT * FROM DB WHERE CD = '$test[0]'";
$result = mysql_query_($sql);
$sql = "INSERT INTO DB(CODE) VALUES ('$test[0]');";
$result = mysql_query($sql);
if($result === true)
{
//Commit
$sql = "commit";
mysql_query($sql);
echo "Committed";
}else {
//Rollback
$sql = "rollback";
mysql_query($sql);
echo "Rollback";
}
}
mysql_close($con);
?>

Answer 1

you need to commit out of the loop, i used $bool to see if there somewhere the $result isn't true
it will look something like :
edit:
breaking from the loop when something is wrong as you don't need to continue looping to other elements.
$bool = 1;
foreach ($ar_1 as $ar1)
{
$test = explode(",", $ar1);
$sql = "SELECT * FROM DB WHERE CD = '$test[0]'";
$result = mysql_query_($sql);
$sql = "INSERT INTO DB(CODE) VALUES ('$test[0]');";
$result = mysql_query($sql);
if($result === false)
{
//Rollback
$bool = 0;
$sql = "rollback";
mysql_query($sql);
echo "Rollback";
break;
}
}
if($bool == 1)
{
//Commit
$sql = "commit";
mysql_query($sql);
echo "Committed";
}
mysql_close($con);
