我遇到 PHP 未从 Fortran 返回打印语句的问题。这个想法是 PHP 执行一个命令来编译 Fortran 文件然后运行它。
系统要求您通过 print 语句输入一个数字,问题是没有显示在 CMD 上,但程序按预期工作 - 当我输入“不正确”的数字时,它会等待我输入“正确”的数字,然后完成执行。
如何让命令行打印 Fortran 文件中嵌套的语句?
PHP 脚本
$<?php
// This is a script to test interoperability between Fortran and PHP
$ExecutionStringOne = "gfortran C:\Users\****\Desktop\Programs\Fortran_Programs\FibSequence.f95 -o C:\Users\****\Desktop\Programs\Fortran_Programs\FibSequenceTest";
$ExecutionStringTwo = "C:\Users\*****\Desktop\Programs\Fortran_Programs\FibSequenceTest.exe";
exec ($ExecutionStringOne);
exec ($ExecutionStringTwo);
?>
Fortran 代码:
! This program will calculate the first 7 numbers in the Fibonacci sequence with user input as well as error checking
Program FibSequence
implicit none
! Defining our global variables
Integer :: acceptValue, n_terms ! Accept Value: 0, 1 - This tracks whether input is correct (0 False, 1 True) , N_terms: Number of terms
real :: timeForSubRoutineStart, timeForSubRoutineEnd, totalTime ! Tracks execution time of subroutine
write(*,*) "Please input an amount of terms to calculate sequentially to - This number can be between 1 and 7"
read *, n_terms
if (n_terms > 0 .AND. n_terms <= 7) then
acceptValue = 1 ! This is true therefore run program (This isnt really needed but for consistency)
Call calculateSequence(n_terms)
else
acceptValue = 0 ! This is false therefore run the read again and keep doing so until the output is correct
do while ( acceptValue == 0 )
write(*,*) "Invalid number please enter one within the given range - Range ( 1 - 7 )"
read *, n_terms
if (n_terms > 0 .AND. n_terms <= 7) then
acceptValue = 1 !Yay correct input
Call calculateSequence(n_terms)
编辑 - 添加了有关问题@roygvib 建议的 ECHO 的新图像,它现在返回一些打印语句
