1
00:00:00,000 --> 00:00:00,360

2
00:00:00,360 --> 00:00:02,530
>> SPIKA: Hebu kuandika mpango katika PHP.

3
00:00:02,530 --> 00:00:05,920
Tofauti na C, ambayo ni lugha ulioandaliwa,
PHP ni kutafsiriwa

4
00:00:05,920 --> 00:00:09,340
lugha, ambayo ina maana kwa haraka kama sisi
kuandika chanzo kanuni zetu katika PHP, tunaweza

5
00:00:09,340 --> 00:00:12,960
tu kuendesha kwa kupita chanzo
code kama mchango katika kile kinachoitwa

6
00:00:12,960 --> 00:00:16,340
mkalimani, mpango ambao lengo
katika maisha ni kusoma PHP chanzo wako

7
00:00:16,340 --> 00:00:20,140
kanuni, juu hadi chini, kushoto na kulia, na
wala, line-na-line, chochote ni

8
00:00:20,140 --> 00:00:21,650
umefanya kuweka kufanya.

9
00:00:21,650 --> 00:00:25,450
Hapa, katika faili iitwayo hello.php,
napenda kuanza kama ifuatavyo.

10
00:00:25,450 --> 00:00:31,140
Open bracket, swali, php, na
kisha chini chini, napenda karibu kwamba php

11
00:00:31,140 --> 00:00:33,700
tag na alama swali, angle bracket.

12
00:00:33,700 --> 00:00:36,570
>> Sasa utapata, juu ya baadhi ya kompyuta, unaweza
unaweza kweli kupata mbali na tu

13
00:00:36,570 --> 00:00:39,710
kufanya wazi bracket, swali,
bila trailing php.

14
00:00:39,710 --> 00:00:42,920
Lakini utapata kwamba kanuni yako ni zaidi
portable na anaendesha kwenye kompyuta zaidi kama

15
00:00:42,920 --> 00:00:45,180
wewe kutumia toleo hili zaidi verbose.

16
00:00:45,180 --> 00:00:49,760
Sasa, katika kati ya hizi vitambulisho, hebu kufanya
kitu rahisi, kama printf, quote

17
00:00:49,760 --> 00:00:53,230
unquote, "hello dunia",
na backslash n.

18
00:00:53,230 --> 00:00:55,610
>> Hebu sasa kuokoa faili
na kuendesha mpango huu.

19
00:00:55,610 --> 00:00:58,490
Ila kukimbia faili hili, tunakwenda
na kupita kwa njia ya PHP

20
00:00:58,490 --> 00:00:59,180
mkalimani.

21
00:00:59,180 --> 00:01:02,980
Basi kitaalam, sisi ni mbio PHP, na
kupita kama chanzo pembejeo code mimi

22
00:01:02,980 --> 00:01:03,840
tu aliandika.

23
00:01:03,840 --> 00:01:10,150
Kwa kufanya hivyo, kwa amri yangu haraka,
Mimi itabidi kufanya php hello.php.

24
00:01:10,150 --> 00:01:12,120
Na huko tunaona, hello dunia.

25
00:01:12,120 --> 00:01:15,220
>> Bila shaka, kwa kuendesha mpango huu, nilikuwa
kujua kwamba mpango iliandikwa

26
00:01:15,220 --> 00:01:18,400
katika PHP, ili Ningependa kujua
kuendesha mkalimani wake.

27
00:01:18,400 --> 00:01:22,290
Bila ya shaka hii ni bora, hasa
wakati, katika C, baada ya kuandaa mpango,

28
00:01:22,290 --> 00:01:25,500
mtumiaji anaweza kukimbia tu bila kuwa
kujua au huduma ya kwamba ni mara moja

29
00:01:25,500 --> 00:01:29,850
Imeandikwa katika C. Lakini tunaweza kufikia kwamba
athari sawa na PHP pia.

30
00:01:29,850 --> 00:01:31,260
>> Hebu kwenda nyuma ya chanzo code yangu.

31
00:01:31,260 --> 00:01:34,970
Saa ya juu sana ya faili hili, hebu
kuongeza shebang, bang makali au

32
00:01:34,970 --> 00:01:39,610
Moderators kumweka, ikifuatiwa na kufyeka
bin kufyeka php, ambayo ni tu

33
00:01:39,610 --> 00:01:44,040
njia ya PHP mkalimani au mpango
kwenye kompyuta fulani.

34
00:01:44,040 --> 00:01:47,830
Hebu sasa ila faili, lakini pia
kufanya faili kutekelezwa

35
00:01:47,830 --> 00:01:49,230
pamoja na someka.

36
00:01:49,230 --> 00:01:52,810
Yatosha kwa faili someka
kwa ajili ya mpango kama PHP kutafsiri

37
00:01:52,810 --> 00:01:56,820
yake, lakini kwa kweli kuendesha programu na
kuangalia kwa kuwa shebang juu ya ni

38
00:01:56,820 --> 00:02:00,470
kujua nini mkalimani kutumia
kutekeleza kanuni, tuna kufanya

39
00:02:00,470 --> 00:02:02,610
faili kutekelezwa pia.

40
00:02:02,610 --> 00:02:09,840
>> Kwa kufanya hivyo, hebu aina chmod pamoja na
x, kwa executable, hello.php.

41
00:02:09,840 --> 00:02:13,730
Na sasa, hebu kukimbia dot
kufyeka hello.php.

42
00:02:13,730 --> 00:02:15,400
Na tena, tunaona hujambo dunia.

43
00:02:15,400 --> 00:02:17,030
Sasa tunaweza kuchukua hatua hii moja zaidi.

44
00:02:17,030 --> 00:02:19,850
Hatuna kufunua dunia
kwamba mpango huu, hello dunia, ni

45
00:02:19,850 --> 00:02:21,140
imeandikwa katika PHP.

46
00:02:21,140 --> 00:02:27,280
Tunaweza kuondoa kwamba faili ugani sasa
vizuri na kufafanua mv hello.php,

47
00:02:27,280 --> 00:02:32,750
atakuwa jina tu hello, na mimi
sasa wanaweza kufanya dot kufyeka hello, na mimi

48
00:02:32,750 --> 00:02:34,090
tena kuona hujambo dunia.

49
00:02:34,090 --> 00:02:36,080
>> Hebu kuchukua hatua hii moja ya mwisho.

50
00:02:36,080 --> 00:02:39,810
Tuseme kwamba mimi si lazima kujua
njia ya PHP kwenye kompyuta juu ya

51
00:02:39,810 --> 00:02:43,980
ambayo mpango huu ili kuwa na kukimbia, lakini mimi
unataka kompyuta kupata hiyo kwa ajili yangu.

52
00:02:43,980 --> 00:02:46,670
Ni zinageuka kuwa mengi ya kompyuta,
kuna mpango ujulikanao

53
00:02:46,670 --> 00:02:50,820
env kwa mazingira, E-N-V, kwamba
unaweza kufikiri kuwa nje kwa ajili yetu.

54
00:02:50,820 --> 00:02:57,020
Basi hebu kwenda nyuma shebang na
mabadiliko hayo kwa kuwa tu env nafasi php.

55
00:02:57,020 --> 00:03:00,290
Hii shebang mpya kuwafundisha
kompyuta kwa kuangalia mazingira yake kwa

56
00:03:00,290 --> 00:03:04,170
mpango, PHP, na kama ni huko,
kutumia kutafsiri mpango huu.

57
00:03:04,170 --> 00:03:06,582
