Replacing lines in files with file contents

Question

I have several files which contain some PHP includes and I want to substitute them with the file contents. The file looks like

foo
<?php
include("file1.php");
?>
bar
baz
<?php
include("file2.php");
include("file3.php");
?>
more content

So after foo should be the content of file1.php and after baz should be first content of file2.php followed by file3.php. I want also remove the <?php and ?> tags in both cases. What is a good way to resolve this?

Assume the following file contents:

1. file1.php: is empty
2. file2.php: <p>Hello
3. file3.php: World</p>

So the resulting file should look like:

foo
bar
baz
<p>Hello
World</p>
more content

The word foo, bar etc. are just expletives within the real file there could be any text.

Answer 1

These are PHP substitutions anyway, so just run it through php:

$ php file-main.php 
foo
bar
baz
<p>Hello
World</p>
more content


$ php file-main.php > file-main-new.php

k=1
while read line
do


        if [[ "${line}" == "<?php" ]] || [[ "${line}" == "?>" ]]; then
        :
        elif [[ "${line}" =~ "include" ]]; then
        ((k++))
        file=$line
                while read include_line
                do
                echo $include_line  | grep -Ev '<\?php|\?>' >> newfile.php
                done <${file:9:9}
       # cat file$k.php >> newfile.php
        else
        echo $line >> newfile.php
        fi

done </tmp/inputfile

Answer 3

Depending on how structured your data is, you could do it like this with sed:

<infile.php sed -n 's:include("\([^"]\+\)");:/&/ { r \1\nd }:p' | 
  sed -f - -e '/<\?php\|\?>/d' infile.php

The first invocation of sed writes a sed script with lines like:

/include("file1.php");/ { r file1.php
d }

Which replace matched lines with the file content they mention. The last sed then executes this script along with /<\?php\|\?>/d, which deletes lines with <?php and ?>.

awk wrapped:

awk '
    /</ || /\?>/ {next;} 
    /include/ {
        if (match($0,"\".*php")){
            f = substr($0,RSTART+1,RLENGTH-1);
            while ( getline < f ){
                print;
            }
        } 
        next;
    } 
    {print;}
' YOURFILE

Can embed in shell, mend your one-liner, or save into an awk script which is recommended...

Answer 5

There would be better awk, sed, perl solutions to this. But I am giving a simple editing tip of vim that can be used here, which is used to insert the contents of a files into other.

1. Delete the <?php and ?> tags.
2. Delete the include line, and insert the respective contents of the file using :r file1.php. This will insert the contents of the file file1.php at the next line from the cursor.
3. Repeat the steps for other such include statements.

example

$ cat file1.txt
This is a content in file1.

The screenshots show the changes

The contents of file1.txt are placed in the mainFile.txt

You can check more about :r in the vim help or this reference link.
