hacky carky a replace
Je v php nějaká fce na odstranění interpunkce z textu ? v manuálu sem ždnou nemohl najít
a druhý dotaz dá se nějak limitovat fce str_replace (popř pužít jiná) aby se provedla jen 5x aby nahradila třeba jen 5 prvních znaků a ostatní nalezené nechala být ?
děkuji

str_replace tohle umi az od verze php5 ale regularni vyrazy to zmaknou.
Umi uz preg_replace()
priklad:
$str = "Ahoj jak se hola vola tah tohle ne";
echo preg_replace("/h/", "*", $str, 2);
vystup:
A*oj jak se *ola vola tah tohle ne
jestli jsi myslel tohle</HTML>

$abc = "áäčďéěíĺľňóôőöŕšťúůűüýřžÁÄČĎÉĚÍĹĽŇÓÔŐÖŔŠŤÚŮŰÜÝŘŽ";
$abc2 = "aacdeeillnoooorstuuuuyrzAACDEEILLNOOOORSTUUUUYRZ";

Jj to je přesně ončo, diky
Richard: proc tak slozite?
$abc = "áäčďéěíĺľňóôőöŕšťúůűüýřžÁÄČĎÉĚÍĹĽŇÓÔŐÖŔŠŤÚŮŰÜÝŘŽ";
$abc2 = "aacdeeillnoooorstuuuuyrzAACDEEILLNOOOORSTUUUUYRZ"; //tvoje písmenka...
$text = strtr($text, $abc, $abc2);
jinak viz manuál u strtr, zvláště komentáře u toho
$abc = "áäčďéěíĺľňóôőöŕšťúůűüýřžÁÄČĎÉĚÍĹĽŇÓÔŐÖŔŠŤÚŮŰÜÝŘŽ";

<HTML>ja tohle natahl ze zdrojaku z dob valky :)
ale je fakt ze je to zbytecne vlastni kdyz na to funkce vicemene uz je..
co se tyce jeste toho omezeni v str_replace tak v usercomments jsem nasel tohle:
function str_replace_count($find,$replace,$subject,$count)
{
$subjectnew = $subject;
$pos = strpos($subject,$find);
if ($pos !== FALSE)
{
while ($pos !== FALSE)
{
$nC = $nC + 1;
$temp = substr($subjectnew,$pos+strlen($find));
$subjectnew = substr($subjectnew,0,$pos) . $replace . $temp;
if ($nC >= $count)
{
break;
}
$pos = strpos($subjectnew,$find);
} // closes the while loop
} // closes the if
return $subjectnew;
}</HTML>

myslím, že by malo ísť aj toto:
$akcent_txt="ťžčýíé= éííéýáéáý";
$abc = array ("á","ä","č","ď","é","ě","í","ĺ","ľ","ň","ó","ô","ő","ö","ŕ","š","ť","ú","ů","ű","ü","ý","ř","ž","Á","Ä","Č","Ď","É","Ě","Í","Ĺ","Ľ","Ň","Ó","Ô","Ő","Ö","Ŕ","Š","Ť","Ú","Ů","Ű","Ü","Ý","Ř","Ž");
$abc2 = array ("a","a","c","d","e","e","i","l","l","n","o","o","o","o","r","s","t","u","u","u","u","y","r","z","A","A","C","D","E","E","I","L","L","N","O","O","O","O","R","S","T","U","U","U","U","Y","R","Z");
$no_akcent_txt = str_replace($abc, $abc2, $akcent_txt);
IMHO
$akcent_txt="ťžčýíé= éííéýáéáý";

$no_akcent_txt = str_replace($abc, $abc2, $akcent_txt);
IMHO
