Hello,

I have a problem calling PHP from Perl and did not find anything about this problem in the web nor in the bug-database. 

I tried this:
---
open(OUTPUTFILE, "| /usr/local/bin/php");
select(OUTPUTFILE);
    --producing my output with perl--
close(OUTPUTFILE);
---

With other Unix-Programs like "cat" everything works fine. Sendmail also uses this syntax for getting input.

I have provided a small sample with 4 cases; case 2 is the one, wich does not work.

I hope, you can help me.

Regards, 
Sebastian

---- sample.pl ----
#!/usr/bin/perl -w

#	Test-Script
######################

use strict;
use warnings;

my $isCGI++ if defined($ENV{'GATEWAY_INTERFACE'}) && $ENV{'GATEWAY_INTERFACE'}=~/CGI/;

	if ($isCGI) {
		use CGI qw(:standard);
		my $cgihandler = new CGI;
		use CGI::Carp qw(fatalsToBrowser);
		
		### case 1 : only printing test and <? phpinfo(); ?>
#		print "Content-type: text/html\n\n";
#		print "test\n";
#		print "<? phpinfo(); ?>\n";
#		exit;

		### case 2: PHP after PERL try
		# Error Message returning: "No input file specified."
		my $acthandle=select();				
			open(OUTPUTFILE, "| /usr/local/bin/php");
			select(OUTPUTFILE);
				print "Content-type: text/html\n\n";
				print "test\n";
				print "<? phpinfo(); ?>\n";
			close(OUTPUTFILE);
		select($acthandle);
		exit;

		### case 3: same routine like calling php, 
		### but calling unix-command "cat"
		# works fine !!!
#		my $acthandle=select();				
#			open(OUTPUTFILE, "| /bin/cat");
#			select(OUTPUTFILE);
#				print "Content-type: text/html\n\n";
#				print "test\n";
#				print "<? phpinfo(); ?>\n";
#			close(OUTPUTFILE);
#		select($acthandle);
#		exit;

		### case 4: calling php via "system" command
		### works, but not optimal...
#		my $acthandle=select();				
#			open(OUTPUTFILE, "> /tmp/cms.temp");
#			select(OUTPUTFILE);
#				print "Content-type: text/html\n\n";
#				print "test\n";
#				print "<? phpinfo(); ?>\n";
#			close(OUTPUTFILE);
#		select($acthandle);
#		exec '/usr/local/bin/php', '/tmp/cms.temp';
#		exit;
	} else {
		print "Demo using CGI.\n";
		exit;
	}

That could be because php detects cgi env. variables present and tries to act accordingly. Could you try compiling php with --enable-cli and copy sapi/cli/php from you php build tree into /usr/local/bin/php?

You can get more information about the differences between cgi and cli versions of php on http://www.php.net/manual/en/features.commandline.php

Hi,

at first of all, thanks for your fast answer. I have tried it yesterday - calling php and processing the output of my perl script works when I am using the cli-feature - but as described in the manual the "Header" functions does not work. 
Therefore I need an cgi-version which is capable of being started in the described way. 

Is this possible or are there any other possiblities to get this running ?

Regards,
Sebastian

You can alsways echo the headers out yourself:
<?php
echo "Content-type: text/html\r\n";
?>

Hi

Can I detect inside my php script if the php binary is running in cli mode ? And can I redefine the "Header" command ?

regards,
Sebastian

This works fine fore me with PHP 4.3.0-dev and PHP 4.2.2:

#!/usr/bin/perl

open(OUTPUTFILE, "| /usr/local/bin/php");
select(OUTPUTFILE);
print "Content-type: text/html\n\n";
print "test\n";
print "<?php phpinfo(); ?>\n";
close(OUTPUTFILE);
exit;

Hello,

if hvried it this way... ButInd teoutput-buffering function of php - my application is very complex and for some reasons I cannot detect at the beginning of the script if a redirect (with the Header/Location command) is necessary.

Sebastian

Sorry, but the bug system is not the appropriate forum for asking
support questions. Your problem does not imply a bug in PHP itself.
For a list of more appropriate places to ask for help using PHP,
please visit http://www.php.net/support.php

Thank you for your interest in PHP.
