PHP set broken processing of keywords in text content _php instance

Sometimes when we display an article, we may need to set broken some keywords and highlight them so that we can quickly find and locate them, so let's take a look at the implementation code.

/** * Keyword Set Broken method * @access public * @param array $options parameter arrays * <li> $info _arr Array Contents </li>  * <li> $search _arr array keyword arrays </li> * @return int or array */function set_arr_keyword_red ($info _arr, $search _arr) {foreach ($search _arr as $search _str) {foreach ($info _arr as $key => $info) {if In_arra
     Y ($key, Array (' item_title ', ' keywords ', ' photo_title ', ' photo_site ', ' content ',))} {$info = Strip_tags ($info);
     $info = Str_replace (', ', $info);
     $q _str_pos = Stripos ($info, $search _str);
      if (false!== $q _str_pos) {$info = Csubstr ($info, $q _str_pos+150);
      $temp = Csubstr ($info, $q _str_pos-150);
      $info = substr ($info, strlen ($temp), 300);
 
      $info = Preg_replace ("/{$search _str}/i", "<font color= ' red ' >{$search _str}</font>", $info);
     if ($info _arr[' match_key ']== ') $info _arr[' match_key '] = $key;
     else {$info = Csubstr ($info, 300);
 }   } $info _arr[$key] = $info;
 } return $info _arr;
$STR = ' Woloveu June ';
$info _arr = Array (' photo_title ' => ' Womejiojd we all surround the static low fart, small June chicken frozen, bubble footbath big ');
$search _arr = Array (' Xiao June ');
$ret = set_arr_keyword_red ($info _arr, $search _arr); Dump ($ret);
