RE: [PHP] Regular Expressions? Help!

Do this. Execute the command at the command line and re-direct output to a file: xxx. Open file xxx with an editor, such as vi. Is there a blank line, or line with JUST a carriage-return (\n) as the last line? -----Original Message----- From: Walker, Roy [mailto:Roy.Walker@GEZWM.com] Sent: Monday, March 25, 2002 3:09 PM To: 'Rick Emery'; 'php-general@lists.php.net' Subject: RE: [PHP] Regular Expressions? Help! No. I think there is a carriage return (\n), but there is not a blank line at the end. -----Original Message----- From: Rick Emery [mailto:remery@excel.com] Sent: Monday, March 25, 2002 3:07 PM To: 'Walker, Roy'; 'php-general@lists.php.net' Subject: RE: [PHP] Regular Expressions? Help! When the exec'd program executes from the command line, does it output a blank line as its last line? -----Original Message----- From: Walker, Roy [mailto:Roy.Walker@GEZWM.com] Sent: Monday, March 25, 2002 2:05 PM To: 'php-general@lists.php.net' Subject: RE: [PHP] Regular Expressions? Help! I just realized why nothing I was trying for the regular expressions wasn't working. The command I am running is a C program on the command line of a Linux box. I can't capture the output, it just gets output onto the screen. I just echo'd $output after the command was run and it was empty. Any ideas? -----Original Message----- From: Rick Emery [mailto:remery@excel.com] Sent: Monday, March 25, 2002 1:54 PM To: 'Walker, Roy' Subject: RE: [PHP] Regular Expressions? Help! well, ya might try: $my_array = explode( "\" ",$output); this would set: $my_vars[0] = "variable1:\"some text info\"" $my_vars[1] = "variable2:\"some text info\"" then, you can do an explode on each of the my_vars another, which might work: <?php $output = "variable1:\"some information\" variable2:\"some information\""; ereg( "(variable[0-9]*):\"(.*)\" (variable[0-9]*):\"(.*)\"", $output, $regs); print "output = $output\n"; print $regs[0]." - 0\n"; print $regs[1]." - 1\n"; print $regs[2]." - 2\n"; print $regs[3]." - 3\n"; print $regs[4]." - 4\n"; ?> WHEN EXECUTED DISPLAYS THIS: C:\>php -q zz.php\ output = variable1:"some information" variable2:"some information" variable1:"some information" variable2:"some information" - 0 variable1 - 1 some information - 2 variable2 - 3 some information - 4 -----Original Message----- From: Walker, Roy [mailto:Roy.Walker@GEZWM.com] Sent: Monday, March 25, 2002 1:31 PM To: 'Rick Emery' Subject: RE: [PHP] Regular Expressions?

Help! I am trying to do a match for an expression and it to a variable from the output of a command: <?php $lines = file ($file); while (list ($line_num, $line) = each ($lines)) { $trimline = trim ($line); $output = shell_exec ("$prog $cmdline $trimline &"); } ?> How can look through $output to set the information returned as different variables the output would look like: variable1:"some information" variable2:"some information" I want to set each variable to a string and write it to a file.
