警告：number_format（）預計參數1雙待，串給出

-4

Warning: number_format() expects parameter 1 to be double, string given in............. on line 200

請告訴我它的解決方案。下面我貼我的整個代碼直到行200

<?php 
function my_session_start() { 
    session_start(); 
} 

function escape($str) { 
    $clean_str = (get_magic_quotes_gpc()) ? mysql_real_escape_string(stripslashes(trim($str))) : mysql_real_escape_string(trim($str)); 
    return $clean_str; 
} 

function _addslashes($str) { 
    $clean_str = (get_magic_quotes_gpc()) ? $str : addslashes($str); 
    return $clean_str; 
} 

function clean($str) { 
    $clean_str = stripslashes (trim($str)); 
    return $clean_str; 
} 

function checkbox_value($str) { 
    if(isset($_POST[$str]) && $_POST[$str]=="on") return 1; 
    return 0;  
} 

function generate_random() { 
    $str = md5(uniqid(rand(),1)); 
    return $str; 
} 

function html_link($str) { 
    $str=correct_href($str); 
    $ret='<a href="'.$str.'">'.$str.'</a>'; 
    return $ret; 
} 

function correct_href($str) { 
    if(!trim($str)) return; 
    if(strcmp(substr($str,0,7),"http://") && strcmp(substr($str,0,8),"https://")) $str="http://".$str; 
    return $str; 
} 

function correct_number_format($str) { 
    $app = new appearance(); 
    $appearance = $app->getAll(); 
    $decimals = $appearance['number_format_decimals']; 
    $point = $appearance['number_format_point']; 
    $separator = $appearance['number_format_separator']; 
    $ereg_str = "/^[0-9]*".$point."*[0-9]+".$separator."*[0-9]*$/"; 
    $ereg_str = str_replace(".", "\.", $ereg_str); 
    if(preg_match($ereg_str, $str)) return 1; 
    return 0;  
} 

function correct_numeric($str) { 
    global $appearance_settings; 
    $point = $appearance_settings['number_format_point']; 
    $separator = $appearance_settings['number_format_separator']; 
    // replace 
    $str = str_replace($point,"#",$str); 
    $str = str_replace($separator,"",$str); 
    $str = str_replace("#",".",$str); 
    return $str; 
} 

function correct_price($str) { 
    global $appearance_settings; 
    $point = $appearance_settings['price_format_point']; 
    $separator = $appearance_settings['price_format_separator']; 
    // replace 
    $str = str_replace($point,"#",$str); 
    $str = str_replace($separator,"",$str); 
    $str = str_replace("#",".",$str); 
    return $str;  
}

什麼是您發佈的代碼的第200行？除了自定義函數外，我在代碼中的任何地方都看不到'number_format（）'......？ – 2015-01-15 15:37:03

我看到太多這樣的問題。花時間學習如何[解釋錯誤並修復代碼]（http://jason.pureconcepts.net/2013/05/fixing-php-errors/）。 – 2015-01-15 15:37:33

其空行。請告訴我解決方案，將其刪除。我會很高興。謝謝 – Ali 2015-01-15 15:38:17

在任一format_price（$ STR）或format_int（$ STR），其中這是發生我會做如下修改：

$result = number_format($str, $decimals, $point, $th_separator);

到

$result = number_format((int)$str, $decimals, $point, $th_separator);

如果號碼包含便士使用

$result = number_format((float)$str, $decimals, $point, $th_separator);
