How increase the performance of this code in php?
or any alternative method to find out the comment if the string starts with # then call at()
or if string starts with "#" then call hash()
here the sample comment is "#hash #at #####tag";
/
/this is the comment with mention,tag
function getCommentWithLinks($comment="#name #tag ###nam1 test", $pid, $img='', $savedid='', $source='', $post_facebook='', $fbCmntInfo='') {

Try This it may be help full
function getResultStr($data, $param1, $param2){
return $param1 != $param2?(''.$data.''):$data;
}
function parseWord($word, $symbols){
$result = $word;

foreach($symbols as $symbol){
if(($pos = strpos($word, $symbol)) !== FALSE){
$status = TRUE;
break;
}
}
if($status){
$temp = $symFlag = '';
$result = '';
foreach(str_split($word) as $char){
//Checking whether chars are symbols(#,#)
if(in_array($char, $symbols)){
if($symFlag != ''){

Answer 2

use strpos or preg_match or strstr
Please refer string functions in php. You can do it in a line or two with that in built functions.
If it not matches better to write a regex.
