PHP 4.0 Bug #8233 Updated: # and // don't work as comment, whereas /*..*/ do

ID: 8233 Updated by: joey Reported By: stefan.peer@tiwag.co.at Old-Status: Open Status: Closed Bug Type: Scripting Engine problem Assigned To: Comments: http://www.php.net/manual/language.basic-syntax.comments.php The "one-line" comment styles actually only comment to the end of the line or the current block of PHP code, whichever comes first. The parser sees ?> as the end of the block of PHP code. The function call is not being interpreted, so the engine does not know what context it is running under.

If you escape ?> in your commented line it should work fine. ie ?> You can reproduce this with the following simple script. (it only happens in logical blocks.) <?php if (true) { // ?> } ?> By contrast this script (outside of a logical block) <?php //?> ?> Would actually print "?>" to the screen Chris --------------------------------------------------------------------------- [2000-12-13 10:30:08] stefan.peer@tiwag.co.at Hi, I had a problem commenting out code fragments. The problem within the following lines is the single-line comment // # as comment seems to have the same problem whereas /* ... */ works fine. if( preg_match( "/(.*?)ELEMENT_(d+){(.*?)}((<.*?>)+)/", $template_lines[$j], $matched) ){ //preg_match("/(.*?)ELEMENT_LAST{(.*?)}((<.*?>)+)/", $template_lines[$j], $matched) $debug_msg .= "Matched /(.*?)ELEMENT_(d+){(.*?)}((<.*?>)+)/ within X"; $iterations = $matched[2]; break; } These lines bring up the errormessage "Parse error: parse error in includes/functions.inc on line 408", where 408 is the last line of the file. I am not sure, whether this has to do with commenting out regular expressions. By the way, I'm using Apache 1.3.14, SuSE 6.4 Linux and I've compiled php with the following switches: ./configure --with-apache=/root/apache/apache_1.3.14 --with-mysql=/usr/local/mysql --with-config-file-path=/usr/lib --with-pdflib=/usr/lib/libpdf.so --with-gdbm=/usr/lib/libgdbm.so --enable-ftp --enable-filepro --with-java=/usr/lib/java --with-ldap --with-openssl=/usr/local/openssl --enable-sysvsem --enable-sysvshm --enable-track-vars --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=8233
