Ako za\u010da\u0165?<\/strong><\/h2>\n\n\n\n

1. Budeme potrebova\u0165 akt\u00edvnu shell konzolu, postup jej aktiv\u00e1cie popisujeme v tomto n\u00e1vode<\/a>. Po pripojen\u00ed si m\u00f4\u017eeme najprv overi\u0165, v akej verzii je Composer nain\u0161talovan\u00fd. Pou\u017eijeme na to pr\u00edkaz:<\/p>\n\n\n\n

composer -v<\/em><\/p>\n\n\n\n

pr\u00edklad v\u00fdsledku:
<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n

Note: Ak potrebujeme Composer v inej verzii, je mo\u017en\u00e9 ho nain\u0161talova\u0165 lok\u00e1lne. V tomto n\u00e1vode pou\u017e\u00edvame glob\u00e1lne dostupn\u00fd Composer.<\/em><\/p>\n\n\n\n

Pomocou pr\u00edkazu cd sa presunieme do prie\u010dinka, v ktorom chceme ma\u0165 projekt ulo\u017een\u00fd, napr\u00edklad:<\/p>\n\n\n\n

cd domena.tld\/web<\/em><\/p>\n\n\n\n

Uk\u00e1\u017eeme si jednoduch\u0161\u00ed z dvoch sp\u00f4sobov, ktor\u00fdm si nain\u0161talujeme bal\u00edk nesbot\/carbon. N\u00e1jdeme ho aj na packagist.org, \u010do je ofici\u00e1lny repozit\u00e1r<\/a> pre Composer.<\/p>\n\n\n\n

2. In\u0161tal\u00e1ciu vykon\u00e1me spusten\u00edm pr\u00edkazu composer require vendor\/balik:<\/p>\n\n\n\n

composer require nesbot\/carbon<\/em><\/p>\n\n\n\n

ak sa bal\u00edk \u00faspe\u0161ne nain\u0161taluje, dostaneme nasledovn\u00fd v\u00fdpis:<\/p>\n\n\n\n

Nako\u013eko sa jedn\u00e1 o prv\u00fd bal\u00edk v na\u0161om projekte, vytvorili sa automaticky s\u00fabory composer.json, composer.lock a taktie\u017e prie\u010dinok vendor.<\/p>\n\n\n\n

M\u00f4\u017eeme do neho zapisova\u0165 manu\u00e1lne, alebo do neho zap\u00ed\u0161e Composer po tom, \u010do pust\u00edme pr\u00edkaz require.  <\/p>\n\n\n\n

-obsahuje bal\u00edky, ktor\u00e9 n\u00e1\u0161 projekt aktu\u00e1lne vyu\u017e\u00edva. Narozdiel od composer.json s\u00fa tu definovan\u00e9 presn\u00e9 pou\u017eit\u00e9 verzie, u ktor\u00fdch m\u00e1me overen\u00e9, \u017ee s nimi n\u00e1\u0161 k\u00f3d funguje.<\/p>\n\n\n\n

-tento prie\u010dinok obsahuje v\u0161etky s\u00fabory nain\u0161talovan\u00fdch bal\u00edkov. Z\u00e1rove\u0148 generuje autoload tried (definuje cesty pre automatick\u00e9 na\u010d\u00edtanie tried n\u00e1\u0161ho projektu (autoloading) a pr\u00edpadne skratky k skriptom, ktor\u00e9 n\u00e1m m\u00f4\u017eu u\u013eah\u010di\u0165 pr\u00e1cu pri tvorbe projektu).<\/p>\n\n\n\n

Ke\u010f si otvor\u00edme composer.json, uvid\u00edme \u010do do neho composer zap\u00edsal:<\/p>\n\n\n\n

S\u00fabor obsahuje k\u013e\u00fa\u010d „require“, n\u00e1zov bal\u00edka, ktor\u00fd je zlo\u017een\u00fd z dvoch \u010dast\u00ed ( n\u00e1zvu jeho tvorcu  a samotn\u00e9ho bal\u00edka) a taktie\u017e verziu. T\u00e1 nemus\u00ed by\u0165 definovan\u00e1 presne, ale napr\u00edklad ako „2.0.*“, \u010d\u00edm ur\u010d\u00edme, \u017ee ak\u00e1ko\u013evek verzia medzi 2.0 a 2.1 je v poriadku.<\/p>\n\n\n\n

Note: ak by sa bal\u00edk nenain\u0161taloval, m\u00f4\u017eeme pou\u017ei\u0165 pr\u00edkaz: composer why vendor\/balik<\/em><\/p>\n\n\n\n

3. Aby sme mohli otestova\u0165 n\u00e1\u0161 bal\u00edk, vytvor\u00edme si jednoduch\u00fd php skript, napr\u00edklad pod n\u00e1zvom carbon.php. Vlo\u017e\u00edme do neho:<\/p>\n\n\n\n

echo „<br>“;<\/p>\n\n\n\n

printf(„Mam %s rokov“, Carbon::createFromDate(1992, 10, 24)\u2192age);<\/p>\n\n\n\n

Po ulo\u017een\u00ed si m\u00f4\u017eeme s\u00fabor otvori\u0165 v prehliada\u010di (v na\u0161om pr\u00edpade je url neviem.uz\/projekt\/carbon.php) a dostaneme tak\u00fdto v\u00fdsledok:<\/p>\n\n\n\n
