PHP cURL command inside foreach loop only shows last result -


i'm new programming, , i've made page using php lets enter userids , add observers using canvas api , worked great. i'm trying enter list of people observed , have process multiple urls , i'm running problems. seems process final userid in box.

any ideas i'm doing wrong? doesn't need run , i'm not worried performance don't need curl commands process simultaneously.

 $observeea = explode ("\n", $observee);    $ch = curl_init();    curl_setopt($ch, curlopt_httpheader, $headers);    curl_setopt($ch, curlopt_customrequest, "put");    curl_setopt($ch, curlopt_returntransfer, 1);    foreach ($observeea $ob2){      if ($idtype == "canvas") {        $url = $domain . "/api/v1/users/$observer/observees/" . $ob2; }      else {        $url = $domain . "/api/v1/users/sis_user_id:$observer/observees/sis_user_id:" . $ob2; }      curl_setopt($ch, curlopt_url, $url);      $resp = curl_exec($ch);      echo $ob2 . "<br>" . $url . "<br>" . $resp . "<br>";    }    curl_close($ch);

the echo on line 13 outputs correct entries url, never gets response until last 1 in list.

it turns out storing string array explode function included hidden return characters, added $ob2 = trim($ob2); foreach loop , works.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
