Multi Regexp – PHP – Fórum – Programujte.com

Ahoj predem se omlouvam za blby dotaz ale vazne na to nemohu prijit. Mam neco takoveho

preg_match_all('/<td class="carImg" width="(.*)" rowspan="2"> <a href="(.*)" onclick="(.*)" > <img src="(.*)" alt="(.*)" width=".*" height="(.*)"\/> <\/a> <\/td>/',$content, $out);

print_r($out);

ved ich uz mas v poli $out.

resp. mozes pomenovat kluce: (?P<nazov_kluca>.*) a v $out ho potom najdes lahsie: $out['nazov_kluca'];

No prave ze nemam. Vymyslel se tedy priklad.

$content = file_get_contents('http://auto.bazos.cz/bmw/');

$out = array();

preg_match_all('~<span class=nadpis><a href="(.*)">(.*)</a></span>(.*)><br>

<a href="(.*)" class="obrazek" border="0" alt="(.*)"></a><div class=popis>(.*)</div><br><br>

</td>

<td valign=top width="15%"><span class=cena><b>(.*)</b></span></td>

<td valign=top width="15%">(.*)</td>

<td valign=top width="7%">(.*)</td>~',$content,$out); 

print_r($out); 

ak tie zhody obsahuju novy riadok, dopln tam modifikator s

http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php

a skus ci vrati preg_match_all nieco ine ako bool(FALSE)

teda $vysledok=preg_match_all(.....); var_dump($vysledok);

lebo ak je $out prazdne, urcite vstupny retazec nevyhovel reg vyrazu...

preg_match_all('/<span class=nadpis><a href="(.*)">(.*)<\/a><\/span>(.*)<br>

<a href="(.*)"><img src="(.*)" class="obrazek" border="0" alt="(.*)"><\/a><div class=popis>(.*)<\/div><br><br>

<\/td>

<td valign=top width="15%"><span class=cena><b>(.*)<\/b><\/span><\/td>

<td valign=top width="15%">(.*)<\/td>

<td valign=top width="7%">(.*)<\/td>

<\/tr>/',$content,$out); 

var_dump($out)

nedal si tam ten modifikator, pridava sa na uplny koniec patternu '/vyraz/s'

http://sk2.php.net/manual/en/reference.pcre.pattern.modifiers.php

preg_match_all('/<span class=nadpis><a href="(.*)">(.*)<\/a><\/span>(.*)<br> 

<a href="(.*)"><img src="(.*)" class="obrazek" border="0" alt="(.*)"><\/a><div class=popis>(.*)<\/div><br><br> 

<\/td> 

<td valign=top width="15%"><span class=cena><b>(.*)<\/b><\/span><\/td> 

<td valign=top width="15%">(.*)<\/td> 

<td valign=top width="7%">(.*)<\/td> 

<\/tr>/s',$content,$out); 

var_dump($out);

Děkuji za trpělivost. :) Dal, potom dostanu prázdné pole.

preg_match_all('~<tr><td width="63%">.*<span class=nadpis><a href="(?P<odkaz>.*)">(.*)<\/a><\/span>.*<img src="(?P<foto>.*)" class="obrazek" border="0" alt=".*">.*<div class=popis>(?P<popis>.*)</div>.*<td valign=top width="15%"><span class=cena><b>(?P<cena>.*)</b></span></td>.*<td valign=top width="15%">(?P<mesto>.*)<br>(?P<psc>.*)</td>.*<td valign=top width="7%">(?P<pocet>.*)</td>.*</tr>~sU',$content,$out);
