PHP scripting... An similiar awk command

[Anthony Smith]

Greetings,

I have the need to take a file and remove the trailing white space as
well as any empty lines... I inherited this script:


cat $1 | awk -v quote="'" \
'
/^[ ]*$/ { next; }
/^.*[ ]*$/ {
printf ("%s\n",subs tr ($0,1,match($0, "[
]*$")-1));
next;
}
{ print $0; }
'


I prefer to do it in PHP. Is there a simpler way?

Why would you prefer to do it in PHP? This is exactly what commands like
perl and awk and sed were designed for, not php.

There are, however, simpler ways to do it. For example, this should
replace your entire script:

sed -e 's/[ \t]*$//' -e '/^$/d' $1

Excellent point Tim.

Well, our web development (I just started in this group) consists of
perl and python in cgi. I want to move to php. Unfortunately, the idea
was to consolidate, but instead I am adding. However when I saw you
could do scripting with PHP I thought I had an answer for Perl and
Python. I do realize that there are some things that Perl and/or Python
just do better. Perl seems to intimidate people and become hard to read
past a certain point. I do understand that part of that is the
programmer's fault. I have no problem with Perl. I just thought since
we are using PHP to do web development why not use it as our scripting
language too. Since sed is not perl, this should be ok.

$a = file($filename) ;
$a = array_filter(ar ray_map('rtrim' , $a));
