I make a table with number 22 as the column name. How to access this column?
content:
I've tryed thest
$obj = Tablename::find(1)->first();
$obj->22;
$obj->'22'; //'syntax error, unexpected ''22''
$obj->"22";
$obj->`22`;
$obj[22];
$arr = $obj->toArray();
var_dump($arr); // array(15) { ["id"]=> string(2) "25" ["out_trade_no"]=> string(14) "14847080930025" ["22"]=> string(0) "2"
$arr[22]; // 'ErrorException' with message 'Undefined offset: 22'
$arr['22']; // 'ErrorException' with message 'Undefined offset: 22'
$arr["22"]; // 'ErrorException' with message 'Undefined offset: 22'
$arr[`22`]; // 'ErrorException' with message 'Undefined index: ' in
$arr[{'22'}]; // 'syntax error, unexpected '{', expecting ']'' in
none works.
edited as the answer implemented: also get null.
var_dump($orders[0]);
var_dump($orders[0]->id);
var_dump($orders[0]->{'22'});
$col = '22';
$res = $orders[0]->{$col};
var_dump($res);
output:

Edit: acording to Paras's comment
Edit2: to make question simple and clear:
migration:
<?php
use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;
class Test extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('tests', function($table)
{
$table->increments('id');
$table->integer('22');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
//
}
}
Model:
<?php
class Test extends Eloquent
{
}
Controller:
public function show()
{
$tests = Test::all();
foreach($tests as $test)
{
Log::info($test->id);
Log::info($test->{'22'});
Log::info($test->{"22"});
Log::info($test->getAttribute("22"));
}
}
data table:
and the log:
