hallo, ich möchte gerne eine php Erweiterung schreiben. Vom Prinzip her die Datei in c nachbilden.

function self_concat($string,$n)
{

$result = "";

  for ($i = 0;$i < $n;$i++)
  {
    $result .=$string;
  }
return $result;
}

ich habe die 5.5.38 php Version per ./configure installiert.

Laut Buch soll ich den folgenden Inhalt

string self_concat(string str, int n)

als myfunktions.def in /def des php Baums speichern.

leider finde ich kein def Verzeichnis in meinem php Baum auch nicht mit

locate /def

Fuer welche PHP Version wurde das Buch denn geschrieben?

thx, das Buch ist von 2005

Verlag:Addison Wesley Das ist ein sehr gutes Buch ☺

Wie sieht die Alternative zu /def aus?

ok, einbisches google ☺ das habe ich gefunden: von 2015 https://www.phpclasses.org/blog/post/304-How-to-Create-a-PHP-C-Extension-to-Manipulate-Arrays--Part-1-Basic-Array-Class-Extension.html

So wie ich es verstanden habe, ist der Prototype erstmal egal.

schnipp...
~/dev/c/php-src/ext/ext_skel --extname=slobel --skel=$HOME/dev/c/php-src/ext/skeleton/
...schnipp

der Pfad finde ich nicht, was ist mit: php-src? kein ext_skel ?

php-src ist hier der Pfad in dem du den Sourcecode von PHP liegen hast.

Im letzten Release der 5.x-Reihe gibt es den Pfad ext/ext_skel jedenfalls.

ok, hab noch mal die 5.5.38 heruntergeladen...

http://php.net/downloads.php

... entpackt... Es gibt kein Verzeichnis → php-src

Auch kein src Verzeichnis 😮

Das ist das Verzeichnis das du heruntergeladen hast. In dem Archiv findest du direkt die ext/ext_skel Datei.

sorry dass ich mich erst jetzt gemeldet habe, hatte viel um die Ohren.

Wenn ich jetzt im Firefox info.php ausführe dann kommt die Version die gewollte habe.

Die myfunctions.def ist im Ordner /ext und hat den inhalt: string self_concat(string str, int n )

in der Console führe ich folgendes aus: ./ext_skel --extname --proto=/home/tomovic/Downloads/php-5.5.38/ext/myfunctions.def

ich überschrieb die myfunctions.c mit dem Inhalt:

PHP_FUNCTION(self_concat)
  {
      char *str = NULL;
      int argc = ZEND_NUM_ARGS();
      size_t str_len;
      zend_long n;
 
 
      char *result; /*points to resulting string*/
      char *ptr;  /*points to the next location we want to copy*/
      int result_length; /*length of resulting string*/
 
 
      if (zend_parse_parameters(argc TSRMLS_CC, "sl", &str, &str_len, &n) == FAILURE)
          return;
 
      /*calculate length of result*/
      result_length = (str_len * n);
 
      result = (char *) emalloc(result_length + 1);
      ptr = result;
      while (n--) {
         memcpy(ptr, str, str_len);
         ptr += str_len;
     }

     *ptr = '\0';
     /* Return result to the scripting engine without duplicating it*/
     RETURN_STRINGL(result, result_length);

     //php_error(E_WARNING, "self_concat: not yet implemented");
 }

in /var/www/html ist die Datei self_concat.php mit dem Inhalt:

<?php
  
   for($i = 1; $i <=3; $i++)
      }
       print self_concat("ThisIsUseless", $i);
       print "\n";
      {
?>

Nach: ./configure --enable-debug --enable-maintainer-zts --with-apxs2 --disable-cgi --enable-cli --disable-pear --disable-xml --without-mysql --enable-maintainer-zts --with-extension --enable-myfunctions

Dann nimm halt stattdessen die richtigen Parameter: Statt --disable-pear also --without-pear, --with-extension gibts auch nicht, du musst schon extension durch die extension ersetzen und -enable-myfunctions kennst das Skript auch nicht.

Das Skript hat eine Hilfe, da steht viel drin...

thx,

--enable-myfunctions ist meine Funktion, die in C geschreiben ist. --with-extension sollte die Funtkion sein, die die Erweiterung zulässt.

Dein Zitat: --with-extension gibts auch nicht, du musst schon extension durch die extension ersetzen Zitat Ende.

ähhh ?

Ich finde diese Option nicht in der Hilfe des Skripts. Hast du dir das schon durchgelesen oder woher hast du diesen Parameter?

https://books.google.de/books?id=AHFNU8EUqmQC&printsec=frontcover&dq=aus+erster+hand+php&hl=de&sa=X&redir_esc=y#v=onepage&q=556&f=false

Seite 556 oben wird der Schalter angegeben.

geht auch nicht, obwohl der 100% richtig ist.

wie meinst du das? extension durch extension ersetzen?

Nochmals etwa deutlicher: In der Hilfe des Skripts finden sich alle von diesem Skript unterstuetzten Parameter. Sieh sie dir an.

./configure --help

./configure -help > help.txt

`configure' configures this package to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/PACKAGE]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  YACC        The `Yet Another Compiler Compiler' implementation to use.
              Defaults to the first program found out of: `bison -y', `byacc',
              `yacc'.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d' given by some make applications.
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  CXXCPP      C++ preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

ja, das habe ich schon gemacht, siehe oben, trotzdem kennt er --with-extension nicht

Extensions:

  --with-EXTENSION=shared[,PATH]

    NOTE: Not all extensions can be build as 'shared'.

    Example: --with-foobar=shared,/usr/local/foobar/

      o Builds the foobar extension as shared extension.
      o foobar package install prefix is /usr/local/foobar/

Du musst EXTENSION durch den Namen der Erweiterung ersetzen, die du bauen willst.
