Php 分析错误：Laravel中的数值文字无效

我已经收到了我的Laravel申请表

结果表明，错误指向以下行：

/* 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');

如果使用PHP7，则应将

08

更改为

8

：

->whereMonth('transaction_date', 8)

我认为您正在使用PHP7.0。您可以使用以下代码执行此操作：

$augledcrdt=Companyledger::WhereIn('frm_ledger',$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');

将“08”改为“08”
