解析错误：Laravel中的数字文字无效

I have get following error in my Laravel Application.

Turns out that the error points to the following lines:

/* August */    
$augledcrdt=Companyledger::WhereIn('frm_ledger',$ledgerlist)->whereYear('transaction_date',$curyear)->whereMonth('transaction_date',08)->where('company_id',$companyids)->sum('credit_amt');
$augleddebt=Companyledger::WhereIn('frm_ledger',$ledgerlist)->whereYear('transaction_date',$curyear)->whereMonth('transaction_date',08)->where('company_id',$companyids)->sum('debit_amt');

/* September */     
$sepledcrdt=Companyledger::WhereIn('frm_ledger',$ledgerlist)->whereYear('transaction_date',$curyear)->whereMonth('transaction_date',09)->where('company_id',$companyids)->sum('credit_amt');
$sepleddebt=Companyledger::WhereIn('frm_ledger',$ledgerlist)->whereYear('transaction_date',$curyear)->whereMonth('transaction_date',09)->where('company_id',$companyids)->sum('debit_amt');

I think you are using PHP 7.0. You can use the following piece of code to do so:

$augledcrdt=Companyledger::WhereIn('frm_ledger',$ledgerlist)->whereYear('transaction_date',$curyear)->whereMonth('transaction_date','08')->where('company_id',$companyids)->sum('credit_amt');
$augleddebt=Companyledger::WhereIn('frm_ledger',$ledgerlist)->whereYear('transaction_date',$curyear)->whereMonth('transaction_date','08')->where('company_id',$companyids)->sum('debit_amt');

You should change 08 to 8 if you're using PHP7:

->whereMonth('transaction_date', 8)
