I'm creating a flatfile database, in one of my functions that I use to add fields to a pre-existing table, I use file() to get the table, the first line is always contains the fields of the table so I can easily just append the new field to the pre-existing fields
public function addFields($table_fields) {
// Make sure he opened a connection to the table
if(empty($this->table_name)) throw new Exception('There is no connection to a table opened.');
// Make sure table_fields is an array
if(is_array($table_fields) === FALSE) throw new Exception('TABLE_FIELDS must be an array');
// Build the data
$table_data = file($this->table_name);
$table_header = $table_data[0].self::$field_deliemeter;
$table_header .= implode(self::$field_deliemeter, $table_fields);
$table_data[0] = $table_header;
// Put the data in the table
file_put_contents($this->table_name, implode(self::$linebreak, $table_data));
}
}
The problem is that, after adding the fieldname to the pre-existing fieldnames using this
$table_data = file($this->table_name);
$table_header = $table_data[0].self::$field_deliemeter;
$table_header .= implode(self::$field_deliemeter, $table_fields);
$table_data[0] = $table_header;
The first index which is 0 seems to contain a linebreak, even though file() is supposed to remove that since file implodes by linebreaks
so for example, if my table was
Name Email Password IP Login_Date
somename someemail 123 123 123
Then after running the class by doing this
$db = new FlatDB;
$fields = array("Last_Click");
$db->openTable('Test');
$db->addFields($fields);
It becomes this
Name Email Password IP Login_Date
Last_Click
Ali ali-trixx@live.com 123 123 123
As you see, it is adding a random linebreak after the first line and I have no idea why is it doing so since file() is supposed to remove linebreaks
Note: $field_deliemeter is "\t"
Does anyone have any idea why is it doing this?
By running a print_r($table_data)
before inserting, I get this
Array ( [0] => Name Email Password IP Login_Date Last_Click [1] => somename someemail 123 123 123 )
