ereg_replace ili str_replace - Replace cijele linije

[ ColdKeyboard @ 14.02.2006. 18:27 ] @

Pravim jedan mali projekat, tj. stranicu na koju bih postavljao logove sa odredjenih
kanala kako bi korisnici koji nisu bili online mogli da dodju i pogledaju sta se desavalo
na kanalu za vreme njihovog odsustva.

Evo sta mi treba, imam log npr koji lici na nesto ovako...

A evo sta bih ja zelio. Znaci da mi neko objasni kako mogu da da npr liniju
koja sadrzi u sebi "Now talking in", da tu citavu liniju obojim npr plavom bojom,
da bude nesto <font color=#nesto> $ta_citava_linija </font>
Znaci treba mi samo primjer kako da definisem sta da radi i kako da radi
replace, pokusavao sam nesto ali nikako da uspijem da mi uradi replace citave
linije...

<td align="center"><b class="txt16b_blue"><?php print "Now talking in"; ?></b></td>
Ovo je i centrira.

Ne, nije ni blizu, to vec znam a to mi i ne treba.

Ovde se radi da $log dobijam iz SQL baze, sada zelim da kada
uzme podatke iz baze, da u njoj zameni npr. citavu liniju ako se u njoj
nalazi data rec ili fraza...

Evo dio koda koji trazi od sql baze podatke i kako ih printa na
stranici...

Code:

    print "    <table width=100% border=0 cellpadding=0 cellspacing=2>";
    $log_trazi = mysql_query("select * from log order by id desc") or die(mysql_error());
    while ($logovi = mysql_fetch_array($log_trazi)) {
    $kanal = $logovi['kanal'];
    $log = str_replace("\n", "<br>", $logovi['log']);
    $dodao = $logovi['dodao'];
    print "
            <tr>
          <td width=7%> </td>
          <td width=86% align=left valign=top><strong>:: $kanal - $dodao ::</strong></td>
          <td width=7%> </td>
        </tr>
        <tr>
          <td> </td>
          <td align=left valign=top>$log</td>
          <td> </td>
        </tr>
        <tr>
          <td> </td>
          <td> </td>
          <td> </td>
        </tr>
        ";
    }
    print "      </table>";

Mozes da proveravas postojanost substringa u stringu (trazis "Now talking"...). Pogledaj http://www.php.net/strpos

Neznam.

Ovako bi trebalo da ide :

Code:

<?
$string = "[17:13] * Now talking in #ck";

if (strstr($string,"*") and strstr(strtolower($string) ,"#ck")) {

$string= eregi_replace("[*](.*)#ck","<fontcolor=\"#0000FF\">* Now talking in #ck</font>",$string);
}

?>

Koliko sam ja skontao, ovako bi trebalo da izgleda code:

Code:
    print "    <table width=100% border=0 cellpadding=0 cellspacing=2>";
    $log_trazi = mysql_query("select * from log order by id desc") or die(mysql_error());
    while ($logovi = mysql_fetch_array($log_trazi)) {
    $kanal = $logovi['kanal'];
    $log = $logovi['log'];
    $dodao = $logovi['dodao'];
    $red = explode('\n', $log);
    print "
            <tr>
          <td width=7%> </td>
          <td width=86% align=left valign=top><strong>:: $kanal - $dodao ::</strong></td>
          <td width=7%> </td>
        </tr>
        <tr>
          <td> </td>
          <td align=left valign=top>";
    foreach ($red as $txt) {
        if (strpos($txt, "* Now talking in") !== false) { $txt = "<font color="#ff0000">".$txt."</font>"; }
        print $txt."<br>";
    }
    print "</td>
          <td> </td>
        </tr>
        <tr>
          <td> </td>
          <td> </td>
          <td> </td>
        </tr>
        ";
    }
    print "      </table>";

Nisam proveravao, ali mislim da bi trebalo da radi.
