如何格式化php数组值并将它们插入数据库[重复]

问题描述：

This is my code where I read csv file (which I get from the bank), parsing it into array & insert it into database:

$csvFile = file('tecajnica.csv');
$keys = str_getcsv(array_shift($csvFile), ';');
foreach ($csvFile as $csvRecord) {
    // combine our $csvRecord with $keys array
    $csv[] = array_combine($keys, str_getcsv($csvRecord, ';'));
}

foreach( $csv as $row) {
$db2 = new PDO ("odbc:as400");
$sqlf93p = $db2->prepare("INSERT INTO..... VALUES (".$row['sifra'].",".$row['Kupovni2']." ......)
$sqlf93p->execute();

This is how my array looks like:

[0]=>
  array(10) {
    ["id"]=>
    string(2) "67"
    ["drzava"]=>
    string(10) "Australija"
    ["sifra"]=>
    string(7) "036 AUD"
    ["VrijediZa"]=>
    string(1) "1"
    ["Kupovni1"]=>
    string(8) "4,5207"
    ["Kupovni2"]=>
    string(8) "4,589597"
    }
[1]=>
  array(10) {
    ["id"]=>
    string(0) ""
    ["drzava"]=>
    string(5) "Ceska"
    ["sifra"]=>
    string(7) "203 CZK"
    ["VrijediZa"]=>
    string(1) "1"
    ["Kupovni1"]=>
    string(8) "0,277098"
    ["Kupovni2"]=>
    string(8) "0,2821"
 }

* * * * * * * etc * * * * * *

So my questions are:

1) Howto convert ["sifra"]=> "203 CZK" to ["sifra"]=> "203" (I want only numeric value to appear before insert)?

2) Howto convert ["Kupovni2"]=> "0,2821" to ["Kupovni2"]=> "0,282100" (I want 6 decimal places before insert)?

Thanks.

Another option could be to replace all non digits using \D+ with an empty string.

$digitsOnly = preg_replace('/\D+/', '', "203 CZK");
echo $digitsOnly; // 203

For appending the zeroes, you might use str_pad:

$parts = explode(',', '0,2821');
$str = implode(',', [$parts[0], str_pad($parts[1], 6, '0', STR_PAD_RIGHT)]);
echo $str; // 0,282100

Php demo

Your code might look like:

foreach( $csv as $row) {
    $db2 = new PDO ("odbc:as400");
    $sifra = preg_replace('/\D+/', '', $row['sifra']);
    $parts = explode(',', $row['Kupovni2']);
    $kupovni2 = implode(',', [$parts[0], str_pad($parts[1], 6, '0', STR_PAD_RIGHT)]);
    $sqlf93p = $db2->prepare("INSERT INTO..... VALUES (". $sifra . "," . $kupovni2 ." ......);
    $sqlf93p->execute();

  1. To get number from a string you can do it this way

    $string = '203 CZK';
echo (int) $string;

OR

$string = '203 CZK';
echo filter_var($string, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);

  1. To make string to length 8 you can use str_pad

    $string = '0,2821';
echo str_pad($string, 8, "0", STR_PAD_RIGHT);

Result :-

0,282100
