问题描述
这里我传递php变量而不是pdf文件路径，如URL []但它显示下面描述的一些胎儿错误
胎儿错误：在C：未捕获的异常 'InvalidArgumentException' 有消息 '// 0无法打开VarStream！'：\xampp\htdocs\VB\FPDI\pdf_parser.php：183堆栈跟踪： ＃0 C：\xampp\htdocs\VB\FPDI\fpdi_pdf_parser.php（64）：pdf_parser-> __构建体（ 'VarStream：// 0'）＃1 C：\xampp\htdocs\\ \\VB\FPDI\fpdi.php（135）：fpdi_pdf_parser-> __构建体（ 'VarStream：// 0'）＃2 C：\xampp\htdocs\VB\FPDI\fpdi.php（ 106）：FPDI-> _getPdfParser（ 'VarStream：// 0'）＃3 C：\xampp\htdocs\VB\mlpdf.php（133）：FPDI-> setSourceFile（'VarStream：// 0'）＃4 C：\ xampp \ htdocs \VB \ TCPDF \ tcpdf.php（3537）：PDF-> Heade R（）＃5 C：\xampp\htdocs\VB\TCPDF\tcpdf.php（3204）：TCPDF->的setHeader（）＃6 C：\xampp\htdocs\VB\ TCPDF \tcpdf.php（3116）：TCPDF-> startPage（''，''，false）＃7 [内部函数]：TCPDF-> AddPage（）＃8 C：\ xampp \ htdocs \ VB\FPDI\fpdf_tpl.php（360）：call_user_func_array（阵列，阵列）＃9 C：\xampp\htdocs\VB\mlpdf.php（167）：FPDF_TPL-> AddPage（）＃10 {main}抛出第183行的C：\ xampp \\\\\\\\\\\\\\\\\\\\\\\\\\\\\ b
其中mlpdf.php是文件名
我尝试过：
here im passing php variable instead of pdf file path as said in URL Using a pdf from a php variable instead of a file | FAQ: Miscellaneous | Setasign[^] but it it shows some fetal error described below

where mlpdf.php is file name
