This article mainly introduces "PHP extension migration to PHP7 extension compatibility parameter adjustment". In daily operation, I believe that many people have doubts about the parameter adjustment of PHP extension migration to PHP7 extension compatibility. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the question of "PHP extension migration to PHP7 extension compatibility parameter adjustment". Next, please follow the editor to study!

Add_assoc_stringl

The method parameters are changed to four.

Add_assoc_stringl (parray, key, value, value_len)

When migrating, simply delete the last parameter.

Add_assoc_string

The method parameters are changed from four to three.

Add_assoc_stringl (parray, key, value)

When migrating, simply delete the last parameter.

Add_next_index_stringl

The method parameters are changed from four to three.

Add_next_index_stringl (parray, value, value_len)

When migrating, simply delete the last parameter.

Add_next_index_string

The method parameters are changed from three to two.

Add_next_index_string (parray, value)

When migrating, simply delete the last parameter.

RETURN_STRINGL

The parameters of the method are changed from three to two.

RETURN_STRINGL (value, length)

When migrating, simply delete the last parameter.

Error: 'INT64_MAX' has not been declared in this scope

The reason is in-depth research. Add a line to # include "php.h"

# include # ifndef INT64_MAX# define INT64_MAX INT64_C (9223372036854775807) # endif#ifndef INT64_MIN# define INT64_MIN (- INT64_C (9223372036854775807)-1) # endif

Solve it.

Create a class

You can refer to the mysqli_objects_new method in the mysqli extension mysqli.c file.

The variable declaration is allocated from the heap to the stack.

For example, the original code was

Zval* sarray_l;ALLOC_INIT_ZVAL (sarray_l); array_init (sarray_l)

Change to

Zval sarray_l;array_init (& sarray_l); zend_hash_get_current_key_ex

The method parameters are changed from six to four.

ZEND_API int ZEND_FASTCALL zend_hash_get_current_key_ex (const HashTable * ht, zend_string * * str_index, zend_ulong * num_index, HashPosition * pos)

When migrating, simply delete the third and fifth parameters.

Error: 'zealTYPERPP' has not been declared in this scope

There is no Zero type _ PP macro, only the definition of the Z_TYPE and Z_TYPE_P macro methods.

H3 error: cannot convert from 'zend_string*' to' const char*'

String processing in PHP7 is stored using zend_string. If you want to turn zend_string into const char. You need to use the ZSTR_VAL () macro method. The code is as follows:

Zend_string * str;char * sptr;.sptr = ZSTR_VAL (str)

Error: 'IS_BOOL' has not been declared in this scope

There is no IS_BOOL type. It is divided into IS_TRUE and IS_FALSE.

Error: 'Zero BVAL' has not been declared in this scope

There is no ZBVAL macro. But it can be determined by whether the type is IS_TRUE and IS_FALSE.

If the type is IS_TRUE, the value is true. The value is false if the type is IS_FALSE.

Error: 'zend_object_store_get_object' has not been declared in this scope

Add the following code:

Static inline hsf_object * hsf_fetch_object (zend_object * obj) / * {* / {return (user_object *) ((char*) (obj)-XtOffsetOf (user_object, std));} / # define Z_USEROBJ_P (zv) hsf_fetch_object (Z_OBJ_P ((zv)

Then change zend_object_store_get_object to Z_USEROBJ_P.

Note that user_object is the structure you define.
