javascript - Trying to create a menu dynamically with php using preg_match_all to my server php documents -

the project consists of lateral menu, contains blog entries. in theory, menu works way: <h1> title of each of blog documents , corresponding href, using php.

---

so each time add new blog entry, appears in menu automatically, did using fopen , fread , saving contents of each php document of blog in variable called $leer.

---

then, used preg_match_all search title of each blog entry , display on menu. can make menu without having add links manually, using scandir url.

---

the problem that, when using preg_match_all in array, gives me many incorrect results, obtaining same <h1> title 4 times without explanation. here code:

$escanear = scandir ("/home/sites/thetoptenweb.com/public_html/post"); $tamanoarray = count($escanear); 

so first, can see, i´m using scandir , count number of pages.

for($i=2;$i<=$tamanoarray-3;$i++){     $abrirfichero = fopen($escanear[$i],"r");     $leer=fread($abrirfichero, filesize($escanear[$i]));             fclose($abrirfichero); } 

then, use for loop , fread read documents. loop made "scan" selected files between second , last-3, because blog entries.

preg_match_all('%<h1>(.*)</h1>%', $leer, $arraymaches); 

so, preg_match_all function title of documents in multi-dimensional array, that array giving me problems i think, because tryed read each result foreach loops, there blank results , don´t know why happens.

foreach ($arraymaches $result) {     foreach ($result $key) {     } }  $cortado=preg_split('%</?h1>%', $key);  echo "<a href=".'"'.$escanear[$i].'"'."><li>".$cortado[0]."</li></a><hr>"; 

finally, used foreach loops access multi-dimensional array of preg_match_all. then, preg_splited results text without html tags , after that, displayed results echo.

hope helps me recognizing problem and, if possible, explanation preg_match_all array because don´t understand how it´s created. suggestions admited. if know better way this, i´ll happy read it. entire code:

<?php     $escanear = scandir ("/home/sites/thetoptenweb.com/public_html/post");     $tamanoarray = count($escanear);     for($i=2;$i<=$tamanoarray-3;$i++){         $abrirfichero = fopen($escanear[$i],"r");         $leer=fread($abrirfichero, filesize($escanear[$i]));         fclose($abrirfichero);         preg_match_all('%<h1>(.*)</h1>%', $leer, $arraymaches);         foreach ($arraymaches $result) {             foreach ($result $key) {             }         }         $cortado=preg_split('%</?h1>%', $key);         echo "<a href=".'"'.$escanear[$i].'"'."><li>".$cortado[0]."</li></a><hr>";                       }                                ?>  

thanks.

just use dom... you'll save trouble.

$menudata = array(); $iter = new directoryiterator('/home/sites/thetoptenweb.com/public_html/post');  foreach ($iter $file) {    if ($file->isfile()) {        $filename = $file->getfilename();        $path = $file->getpathname();        $dom = new domdocument();        $dom->loadhtmlfile($path);         $titlenode = $dom->getelementsbytagname('h1')->item(0);        if ($titlenode) {           $title = $titlenode->nodevalue;           $menudata[$filename] = $title;        }    } } 

now have stuff in $menudata can loop on , output links, assuming filename appropriate url. alternatively, output links in loop directly it's wiser separate things. create function data need, , use data output.

but better solution pick blog platform , use that, spend time writing importer , adjusting , feel suit.
