a kaa ar txt failiem var nodroshinaaties, lai lietotaajs netiek klaat tavai txt datubaazei? man tas neliekas eerti. gan jau ka ir kaads veids, bet tas vareetu buut chakars. ja kaads prasa man, iesaku lietot mysql.

Jakonfiguree apache un jaaizliedz .txt faili (vai arii lasiit direktoriju kuraa atrodas muusu txt db)..

Ja ir atljauts izmantot .htacess failus vai ir pieeja konfigam (tas ir tavs pasha webserveris) tad easy ja nav (teiksim hosteejies pie kaada) tad var meegjinaat datus glabaat nevis .txt failos bet .php failos un saakumaa un beigaas iebakstiit <? un ?>

Liidz ar to pie nolasiishanas buus jaaizmet faila pirmaa peedeejaa rinda tachu useris pa taisno failu apskatiit nevarees..

Protams visaadaa zinjaa tas ir krietni saregzjiitaak (zinaamos jautaajumos kaa atlasiishana,sorteeshana, ierakstu limiteeshana) nekaa straadaat ar kaadu no sql datubaazeem (mysql,pgsql u.c.)

Txt formāts no īstas datubāzes ir tikpat tāls kā cūkkūtiņa no kosmosa stacijas. Txt failā var tikai glabāt informāciju, visāda datu atlasīšana un meklēšana txt failā būs nejēdzīgi neērts pasākums. Bet darīt jau var.

Ērti ir glabāt masīvus txt failā izmantojot funkcijas serialize() un unserialize().

Windows vidē gan laikam ar txt failiem var strādāt arī kā ar datu tabulām, ja darbojas caur odbc - iekš odbc var noformēt comma-delimited teksta failu kā datu avotu.

Nee nu kapeec?

ja tu vari uzrakstiit normaalu interfeisu funkcijas, sortinga atbalstu (aiz kam taadas lietas eksistee (ir uzkodeetas) kaa flat file databases) tad saliidzinaajums par cuukkuutinju ir nevietaa.. un pie maziem datu apjomiem cuukkuutinji liek iekshaa "kosmosa staciju" ka nemetas (var pamekleet googlee 'php text file databases' vai 'flat file databases')..

p.s. jaa pods.lv vismaz kaadreiz (iespeejams ka veelarvien ja CLX nav ko mainiijis) griezhas uz .txt
