How to read columns from text file and insert in database php - php

Question

I have a text file with multiple rows and columns inside them.
I want to read each and every row and column, store them in array and save all data in database using cakephp.
Below is my code, I wrote some row and column reading logic which i wants to implement.
Please help me to do this critical thing.
public function importfile(){
$fp = 'C:/wamp64/www/jhraut/webroot/uploads/120518SU';
$handle = fopen($fp, "r");
if ($handle) {
while (($line = fgetc($handle)) !== false) {
$data['GunNo'] = "first 5 characters of $line is GunNo than 1 character is space";
$data['FatGun'] = "Second 3 characters of $line is FatGun than 1 character is space";
$data['LoinGun'] = "Third 3 characters of $line is LoinGun than 1 character is space";
$data['ScaleWt'] = "fourth 5 characters of $line is ScaleWt than 1 character is space";
$data['Partial'] = "if P or M than 1 character is space";
$data['TimeofReading'] = "last 8 characters of $line is TimeofReading";
echo $line;
}
$this->Event_program->saveAll($data);
}
fclose($fp);
exit;
}
My file data
parti 011 058 145.6 P 06:37:01
00002 016 049 175.8 06:37:08
00003 009 072 150.8 06:37:15

Answer 1

Try something like this:
// set path to file
$file = WWW_ROOT.'uploads/120518SU';
// check if file exists
if (file_exists($file)) {
// Reads an entire file into an array with file() method
// and loop array
foreach (file($file) as $line) {
// convert line value to new array
$arr = explode(' ', $line);
// do something with your data..
$data = [
'GunNo' => $arr[0],
// ...
];
$entity = $this->EventProgram->newEntity($data);
$this->EventProgram->save($entity);
}
}
Update with some test:
$line = '00003 009 072 150.8 06:37:15';
$arr = explode(' ', $line);
print_r($arr);
// output
Array
(
[0] => 00003
[1] => 009
[2] => 072
[3] => 150.8
[4] =>
[5] =>
[6] =>
[7] => 06:37:15
)
$line = 'parti 008 069 134.8 P 06:37:58';
// ..
Array
(
[0] => parti
[1] => 008
[2] => 069
[3] => 134.8
[4] => P
[5] =>
[6] => 06:37:58
)
Then:
// do something with your data..
$data = [
// ...
'TimeofReading' => end($arr),
];
Update: reading as csv file
Use fgetcsv()
The fgetcsv() function parses a line from an open file, checking for
CSV fields.
The fgetcsv() function stops returning on a new line, at the specified
length, or at EOF, whichever comes first.
This function returns the CSV fields in an array on success, or FALSE
on failure and EOF.
fgetcsv(file,length,separator,enclosure);

Answer 2

Use regular expression. As you have some rows having few fields empty splitting with space might cause problem.
preg_match('/(.{5}) (.{3}) (.{3}) (.{5}) (.{1}) (.{8})/', $line, $op);
$data['GunNo'] = $op[1];
$data['FatGun'] = $op[2];
$data['LoinGun'] = $op[3];
$data['ScaleWt'] = $op[4];
$data['Partial'] = $op[5];
$data['TimeofReading'] = $op[6];
echo $op[0];
