debug php code code example
Example 1: how to debug in php
ini_set('display_errors', 'On');
error_reporting(E_ALL);
Example 2: php best debugging functions
I am using two ways to debug code
one is print the data and die the function in specific point.
print_r($data);die;
second one is writing log file in specific point in code.
function write_log($log_msg)
{
$log_filename = "logs";
if (!file_exists($log_filename))
{
mkdir($log_filename, 0777, true);
}
$log_file_data = $log_filename.'/debug.log';
file_put_contents($log_file_data, $log_msg . "\n", FILE_APPEND);
}
write_log("Writing Log");
$a = array(
array('id' => '1','date' => '09-04-2018','length' => '10'),
array('id' => '2','date' => '09-04-2018','length' => '20'),
array('id' => '1','date' => '10-04-2018','length' => '11')
);
write_log(print_r($a,1));
Example 3: debug php
$a = 123
echo ($a);
exit;
$array = array(
1 => 'apple',
2 => 'banana',
)
echo "<pre>";
print_r($array);
echo "</pre>";
echo "<pre>";
var_dump($array);
echo "</pre>";
dd($array)
pr ($array);
$json = {"a":"123"}
pr (json_encode($json));
exit;
print_r (json_encode($json));
exit;
