Foreach with different final loop












-2














I'm trying to create a foreach loop which changes the values of two variables. The last iteration of the loop is slightly different (removed comma at the end) - I can't seem to get it to work.



This is what I have so far



$rego_columns = [
"make",
"model",
"year",
"rego",
];

foreach ($rego_columns as $key => $regcolex) {
if ($key === key($rego_columns)){
$table_values = "'".$record["$regcolex"]."'";
$table_columns = "`.$regcolex.`";
} else {
$table_values = "'".$record["$regcolex"]."',";
$table_columns = "`.$regcolex.`,";
}
}

As you are effectively trying to map $record to your $rego_columns, I suggest using array_map to retrieve the values.



Then you can use implode to add the wrapping quotes or backticks around the array values.



Example https://3v4l.org/h70pO



$rego_columns = [
"make",
"model",
"year",
"rego",
];

$record = ['make' => 'A', 'model' => 'B', 'year' => 'C', 'rego' => 'D'];

$tableValues = array_map(function($r) use ($record) {
return $record[$r];
}, $rego_columns);

$tableColumns = '`' . implode('`,`', $rego_columns) . '`';
$tableValues = '"' . implode('","', $tableValues) . '"';


echo 'INSERT INTO table_name (' . $tableColumns . ') VALUES (' . $tableValues . ')';


Results in



INSERT INTO table_name (`make`,`model`,`year`,`rego`) VALUES ("A","B","C","D");




If you needed the dots included around the table column values for some reason, change the implode to:



$tableColumns = '`.' . implode('.`,`.', $rego_columns) . '.`';
$tableValues = '"' . implode('","', $tableValues) . '"';


Results in: https://3v4l.org/1DI76



INSERT INTO table_name  (`.make.`,`.model.`,`.year.`,`.rego.`) VALUES ("A","B","C","D")




As a side note, I strongly suggest using prepared statements whenever using variable data with a database. And adopting this to map the values to the placeholders.



Example https://3v4l.org/kcl4m



$tableValues = array_map(function($r) use ($record) {
return $record[$r];
}, $rego_columns);
$placeholders = implode(',', array_fill(0, count($tableValues), '?'));
$tableColumns = '`' . implode('`,`', $rego_columns) . '`';

$query = 'INSERT INTO table_name (' . $tableColumns . ') VALUES(' . $placeholders . ')';

$stmt = $pdo->prepare($query);
$stmt->execute($tableValues);
