[root@Michael php-5.5.0]#
make ||
make ZEND_EXTRA_LIBS='-liconv'
[root@Michael php-5.5.0]# make install

3.自定义扩展开发

[
root@
Michael
ext]# vi michael/config.m4
dnl Otherwise use enable:
dn1 PHP_ARG_ENABLE(michael, whether to enable michael support,
dn1 Make sure that the comment is aligned:
dn1 [ --enable-michael Enable michael support])
修改后:
dnl Otherwise use enable:
PHP_ARG_ENABLE(michael, whether to enable michael support,
Make sure that the comment is aligned:
[ --enable-michael Enable michael support])
[root@Michael michael]#vi michael.c
【往ZNED引擎注册新方法】

const zend_function_entry michael_functions[] = {
PHP_FE(confirm_michael_compiled, NULL) /* For testing, remove later. */
PHP_FE_END /* Must be the last line in michael_functions[] */
};
修改后
const zend_function_entry michael_functions[] = {
PHP_FE(confirm_michael_compiled, NULL) /* For testing, remove later. */
PHP_FE(xuchao, NULL) /* For testing, remove later. */
PHP_FE(test, NULL) /* For testing, remove later. */
PHP_FE_END /* Must be the last line in michael_functions[] */
};

【输出到PHPINFO】
PHP_MINFO_FUNCTION(michael)
{
php_info_print_table_start();
php_info_print_table_header(2, "michael support", "enabled");
php_info_print_table_end();
/* Remove comments if you have entries in php.ini
DISPLAY_INI_ENTRIES();
*/
}
修改后
PHP_MINFO_FUNCTION(michael)
{
php_info_print_table_start();
php_info_print_table_header(2, "michael support", "enabled");
php_info_print_table_row(2, "Michael Module", "This is frist php-extent!!!");
php_info_print_table_row(2, "version", "Michael-1.0");
php_info_print_table_end();
/* Remove comments if you have entries in php.ini
DISPLAY_INI_ENTRIES();
*/
}

【增加注册的方法】
PHP_FUNCTION(xuchao)
{
char *arg = NULL;
int arg_len, len;
char *strg;
php_printf("Hello World!\n");
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &arg, &arg_len) == FAILURE) {
return;
}
len = spprintf(&strg, 0, "Congratulations! You have successfully modified ext/%.78s/config.m4. Module %.78s is now compiled into PHP.", "michael", arg);
RETURN_STRINGL(strg, len, 0);
}
PHP_FUNCTION(test)
{
char *arg = NULL;
int arg_len, len;
double max_len = 900000000;
char *strg;
double id;
double cont=0;
php_printf("Start:\n");
for(id = 0;id < max_len;id++){
cont = cont + max_len;
}
php_printf("END:%f",cont);
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &arg, &arg_len) == FAILURE) {
return;
}
len = spprintf(&strg, 0, "Congratulations! You have successfully modified ext/%.78s/config.m4. Module %.78s is now compiled into PHP.", "michael", arg);
RETURN_STRINGL(strg, len, 0);
}
------------------------
------------------------
------------------------
------------------------
-----------------
[root@Michael michael]#vi php_michael.h
【修改.h头文件】
PHP_FUNCTION(confirm_michael_compiled); /* For testing, remove later. */
改为：
PHP_FUNCTION(confirm_michael_compiled); /* For testing, remove later. */
PHP_FUNCTION(xuchao); /* For testing, remove later. */
PHP_FUNCTION(test); /* For testing, remove later. */
-----------------------------------------------------------------------------------------------------------------
[root@Michael michael]#/usr/local/php/bin/phpize
[root@Michael michael]#./configure
[root@Michael michael]#make
[root@Michael michael]#make install
OR
[root@Michael php-5.5.0]#./buildconf --force
[root@Michael php-5.5.0]#./configure --help | grep michael
--enable-michael Enable michael support
[root@Michael php-5.5.0]#./configure --enable-michael
[root@Michael php-5.5.0]#make
[root@Michael php-5.5.0]#make install
[root@Michael
php-5.5.0]#
/usr/local/php/bin/php -m | grep michael
michael
[root@Michael html] vi phpinfo.php
<?php
phpinfo();
?>
[root@Michael html] service php-fpm restart
以上步骤会遇到各种奇葩问题，Notice:干净系统级版本对应上,
如果为空，把相应的michael.so 注册到php.ini.

4.扩展测试篇
|
[root@Michael html]# more test.php
<?php
$id;
$max_len = 900000000;
$cont = 0;
for($id=0;$id < $max_len; $id++){
$cont = $cont + $max_len;
}
echo $cont;
?>
[root@Michael php-5.5.0]#more index.php
<?php
test();
?>
密集型过亿级别计算,差距竟然这么大。
