import csv with php to mysql

November 24, 2022

I’m importing a csv file into a mysql table with php.
Now I’m going to put some lines as I have in the csv. csv has no header.

I leave the script of how I created the table in mysql:

CREATE TABLE `Areceber` (
  `Id` int NOT NULL AUTO_INCREMENT,
  `N_utente` varchar(45) DEFAULT NULL,
  `Ano` varchar(10) DEFAULT NULL,
  PRIMARY KEY (`Id`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

now I will put the html script:

<form method="post" action="conexaoexcel1.php" enctype="multipart/form-data">
  <input type="file" name="file"/>
  <input type="submit" name="submit_file" value="Submit"/>
</form>

and now the page conexaoexcel1.php:

$file = $_FILES["file"]["tmp_name"];
$file_open = fopen($file,"r");
while(($csv = fgetcsv($file_open, 1000, ";")) !== false)
{

    foreach ($csv as $key => $value){   

        $Id = str_getcsv($value[0], ',');       
        var_dump($Id);

    }
}

Now when I var_dump the first column it returns like this:

array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "2" } array(1) { [0]=> string(1) "3" } array(1) { [0]=> string(1) "4" } array(1) { [0]=> string(1) "5" } array(1) { [0]=> string(1) "6" } array(1) { [0]=> string(1) "7" } array(1) { [0]=> string(1) "8" } array(1) { [0]=> string(1) "9" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "2" }

Up to the line that has the number nine it returns fine, but when it starts on the line that has the number 10, it only returns the number 1 without the zero and so on. Can you help solve the problem?

>Solution :

Your $csv is already an array of data, and to output first column, use $csv[0] without looping.

$file = $_FILES["file"]["tmp_name"];
$file_open = fopen($file,"r");
while(($csv = fgetcsv($file_open, 1000, ";")) !== false)
{

    $Id = $csv[0];       
    var_dump($Id);
}

Just check if your delimiter is right. If it’s comma delimited change line

while(($csv = fgetcsv($file_open, 1000, ";")) !== false)

while(($csv = fgetcsv($file_open, 1000, ",")) !== false)

Otherwise it should work.
