I am learning php. I want to write string to file, but nothing happens. How can I debug it? I have experience with python. there I could use terminal to try small code snippets, but I don't know how check code in php.
$myFile = "testFile.txt";
$fh = fopen($myFile, 'w');
$stringData = "Bobby Bopper\n";
$myvar = fwrite($fh, $stringData);
$stringData = "Tracy Tanner\n";
fwrite($fh, $stringData);
fclose($fh);
Unless you really need to use file handlers, just do this:
$myFile = "testFile.txt";
$stringData = "Bobby Bopper\nTracy Tanner\n";
file_put_contents($myFile,$stringData);
Debugging in php always starts with turning up error reporting
<?php
error_reporting(E_ALL);
ini_set('display_errors', true);
$myFile = "testFile.txt";
$fh = fopen($myFile, 'w');
$stringData = "Bobby Bopper\n";
$myvar = fwrite($fh, $stringData);
$stringData = "Tracy Tanner\n";
fwrite($fh, $stringData);
fclose($fh);
chances are good that you will now see a somewhat descriptive error message. googling php error messages is often helpful.
This looks like correct code. Try checking to make sure you have the right file path. An easy way to do this is
$myFile = "testFile.txt";
$fh = fopen($myFile, 'w');
$stringData = "Tracy Tanner\n";
fwrite($fh, $stringData);
fclose($fh);
$fh = fopen($myFile, 'r');
$value = fgets($fh);
echo $value;
fclose($fh);
