/* Use the strpos function in PHP to filter keywords */
// Keyword filtering function

Function keyWordCheck ($ content ){
// Remove the blank
$ Str = trim ($ content );
// Read the keyword text
$ KeyWords = @ file_get_contents ('Keywords. TXT ');
// Convert to an array

$ Arr = explode (",", $ keyWords );

// Traversal detection

$ K = count ($ arr );
Echo $ k;
Echo"
";

For ($ I = 0, $ k; $ I <$ k; $ I ++ ){
Echo $ str;
Echo "keyword being detected:". $ arr [$ I];
Echo"
";

// Skip this loop if the array element is null
// If ($ arr [$ I] = '')
//{
// Continue;
//}

Echo stripos ($ str, $ arr [$ I]);

// If a keyword is detected, the matching keyword is returned and the running is terminated.
// If (strpos ($ str, $ arr [$ I])> = 0 ){
// $ I = $ k;
// Return $ arr [$ I];
// Echo "detected Keywords:". $ arr [$ I];
// Echo"
";
//}
}
// If no keyword is detected, false is returned.
Return false;
}

$ Content = 'here is the Zhuhai text content WWW to be published... ';

// Filter keywords
$ KeyWord = keyWordCheck ($ content );
Echo $ keyWord;


?>

Echo stripos ($ str, $ arr [$ I]); // no detected
Echo stripos ($ str, "Zhuhai"); // detected

KeyWords. TXT content
Zhuhai, Central, Macao, and airport

Here is the Zhuhai text content WWW to be published... Keyword being detected :? Zhuhai
Here is the Zhuhai text content WWW to be published... Keyword being detected: Central
Here is the Zhuhai text content WWW to be published... Keyword being checked: Macao
Here is the Zhuhai text content WWW to be published... Keyword being checked: Airport


Extremely stuffy

------ Solution ----------------------
BOM header length, but not displayed
You can change the keyWords. TXT file to the following:
, Zhuhai, Central, Macau, airport

That is, the front is a comma.
