Adding a \n newline symbol when using sprintf in PHP

Question

I'm trying to export existing data from a MySQL database, into ruby commands I can run with rake db:seed.

Here's my code.

# Generate db:seed data for proveedores.
$proveedores = R::findAll('tbproveedores');
$proveedoresE = R::exportAll($proveedores);

foreach ($proveedoresE as &$p) {

    $line = 'BookSupplier.create(company: "%s", city: "%s", country: "%s", address: "%s", telephone: "%s", contact: "%s", email: "%s", website: "%s"\n';
    $exportedLine = sprintf($line, $p['empresa'], $p['ciudad'], $p['pais'], $p['direccion'], $p['telefono'], $p['personacontacto'], $p['email'], $p['website']);
    var_dump($exportedLine);
    fwrite($seeds, $exportedLine);
    echo "<br />";
}

Notice the \n newline symbol at the end of the $line variable. I read online that that was all that is needed to use a newline.

The output of my code above is (vertabim, a long line):

BookSupplier.create(company: "Pearson", city: "Lima", country: "Peru", address: "Av. Limon", telephone: "4673535421", contact: "Javier", email: "", website: ""\nBookSupplier.create(company: "Project Management Institute - PMI", city: "Pennsylvania", country: "Estados Unidos", address: "Newtown Square, Pennsylvania", telephone: "1", contact: "Limberg Morales", email: "", website: "http://www.pmi.org/"\nBookSupplier.create(company: "UVirtual - Centro de Excelencia", city: "Santa Cruz", country: "Bolivia", address: "Av. Irala 585", telephone: "1", contact: "Limberg Morales", email: "", website: ""\nBookSupplier.create(company: "Ábaco de Rodolfo Depalma", city: "Buenos Aires", country: "Argentina", address: "Viamonte 1336, 4° (C1053 ACB) Buenos Aires", telephone: "5411-43711675", contact: "Limberg Morales", email: "", website: "http://www.abacoeditorial.com.ar/"\nBookSupplier.create(company: "Pablo Lledó - ProjectManagement", city: "Canadá", country: "Estados Unidos", address: "Victoria, BC, Canadá", telephone: "1", contact: "Limberg Morales", email: "", website: ""\n

I'd like each call to be in it's own line, following my newline insertion. Any suggestions on what I'm doing wrong?

Answer 1

If you can't (or don't want to) switch to double quotes, you can insert a newline using the ASCII code like so:

> php
<?php printf('line one%cline two', 10);^D
line one
line two
>

The %c lets you insert any ASCII code and 10 is the code for a newline.
