كيفية التعامل مع هذه الحروف الخاصة ؟

[apitos]

السلام عليكم،

يعرض لي المتصفح الجملة التالية :

أحد الجيران

هكذا :

أحد&.#8237; &.#8236;الجيران&.#8237; &.#8236;

وقد قرات ان الحرفين الخاصين :

#8236& و #8237&

يستعملان للحفاظ على كتابات النصوص ذات الاتجاه LTR داخل النصوص العربية ذات الاتجاه RTL.

&.#8237; myLTRtext in RTL language &.#8236;

ولكن الامر حسب المثال لدي، فأنه تم اضافة هذين الحرفين رغم وجود نص عربي فقط.

فكيف يتم عرض النص بتعويض/الغاء الخرفين في نص الاخراج على المتصفح ؟

شكراً.

        return trim(nl2br(stripslashes($Str)));
    } 

اظن وجب تغيير/اضافة شيء ما لهذه الدالة :

أخي جرب أن تضيف هذا السطر الى الهيدر
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>

و ان لم يعمل معك الرجاء وضع HTML الصفحة التي يظهر فيها الخطأ كاملا

اهلا اخي الكريم.

هنا في هذا الموضوع، تجد مرفق ملف صفحة الاندكس :

http://www.swalif.net/softs/swalif44/softs279913/

صورة توضيحية للمشكل :

[idontknow]

أخي هل تظهر المشكلة على كل المتصفحات و ان لم يكن فعلى أيها تظهر

هل يمكن تعطيني رابط الخبر الفعلي الذي تظهر به هذه الرموز

السبب أخي أني لم أستطع اعادة صناعة الخطأ على جهازي فكل شيئ يظهر بشكل طبيعي

شكرا لك

[apitos]

رفعت الخبر الى موقعي وها هو الرابط :

أخي
غير ال function make safe الى هذه

//---------------------------------------------------
//------    replace  and clan  functions    ------//
//---------------------------------------------------
    function makeSafe($Str)
    {
        $Str = preg_replace( "#(\?|&|&)(PHPSESSID|s|S)=([0-9a-zA-Z]){32}#e", "", $Str );
        $Str = str_replace(array("&","<",">"),array("&","<",">",),$Str);
        $Str = preg_replace('#(<[^>]+)style[\x00-\x20]*=[\x00-\x20]*([\`\'\"]*).*expression[\x00-\x20]*\([^>]*>#iU',"$1>",$Str);
        $Str = preg_replace('#(<[^>]+)style[\x00-\x20]*=[\x00-\x20]*([\`\'\"]*).*behaviour[\x00-\x20]*\([^>]*>#iU',"$1>",$Str);
        if(version_compare(phpversion(),"5.0.0", "<")){
        $Str = preg_replace('#(<[^>]+)style[\x00-\x20]*=[\x00-\x20]*([\`\'\"]*).*s[\x00-\x20]*c[\x00-\x20]*r[\x00-\x20]*i[\x00-\x20]*p[\x00-\x20]*t[\x00-\x20]*:*[^>]*>#iUu',"$1>",$Str);
        $Str = preg_replace('#(&\#*\w+)[\x00-\x20]+;#u',"$1;",$Str);
        $Str = preg_replace('#(&\#x*)([0-9A-F]+);*#iu',"$1$2;",$Str);
        $Str = preg_replace('#(<[^>]+[\x00-\x20\"\'])(on|xmlns)[^>]*>#iUu',"$1>",$Str);
        $Str = preg_replace('#([a-z]*)[\x00-\x20]*=[\x00-\x20]*([\`\'\"]*)[\\x00-\x20]*j[\x00-\x20]*a[\x00-\x20]*v[\x00-\x20]*a[\x00-\x20]*s[\x00-\x20]*c[\x00-\x20]*r[\x00-\x20]*i[\x00-\x20]*p[\x00-\x20]*t[\x00-\x20]*:#iUu','$1=$2nojavascript...',$Str);

        }
        $Str = preg_replace('#</*\w+:\w[^>]*>#i',"",$Str);
        do {
            $oldstring = $Str;
            $string = preg_replace('#</*(applet|meta|xml|blink|link|style|script|embed|object|iframe|frame|frameset|ilayer|layer|bgsound|title|base)[^>]*>#i',"",$Str);
        } while ($oldstring != $Str);
    $Str =preg_replace('#\&amp\;\#8236#', ';#8236', $Str);
        return $Str; 

}

لو تلاحظ فان كل ما فعلته هو اضافة هذا السطر في النهاية

    $Str =preg_replace('#\&amp\;\#8236#', ';#8236', $Str); 

أعتقد أن المشكلة كانت في هذا السطر

$Str = preg_replace('#(&\#*\w+)[\x00-\x20]+;#u',"$1;",$Str); 

و لكن الظاهر أنه للحماية من ال XSS لذلك نتركه و نزيل أثره السلبي فقط
بعدها قم بحذف الخبر ثم ادخله من جديد و لنرى النتيجة

[apitos]

ولكن حسب المثال الذي فوق هناك الحروف الخاصة التالية :

#8236 - #8237 - #35

يعني بصورة عامة كيف ستكتب الدالة preg_replace لمعالجة جميع الحروف الخاصة المشابهة ؟

شكراً.

[idontknow]

الدالة التي ستعالج كل الحالات مرة واحدة هي
هذه الدالة ستعالج كل الحالات مثل
#12
#123
#1234

       $Str =preg_replace('#\&amp\;\#(\d{2,4})#', ';#$1', $Str); 

و لكني أفضل أن يتم معالجة الحالات الشاذة كل على حدة
يعني من الأفضل أن تضع 3 أوامر كالاتي
$

Str =preg_replace('#\&amp\;\#8236#', ';#8236', $Str);
    $Str =preg_replace('#\&amp\;\#8237#', ';#8237', $Str);
    $Str =preg_replace('#\&amp\;\#35#', ';#35', $Str); 

طبعا ازل الدالة الاضافية التي كتبناها سابقا و ضع بدالها اما الدالة العامة الأولى أو ال 3 دوال الاحقة
في حفظ الله

[apitos]

أضفتها في آخر الدالة ولكن عند ارسال الخبر من جديد واستعراضه يقيت تلك الحروف الخاصة تشوه الخبر.

لا ادري ما المشكلة ؟

حتى اني استعملت حلا آخر :

$Str = str_replace(array("&# 8236;","&# 8237;"),"",$Str); 

ولكن لم يجدي نفعاً.

راس ونص الخبر يتم معالجتهما قبل ارسالهما الى القاعدة هكذا :

$news_head = $apt->format_post($post_head);
$post = $apt->format_post($post); 

والدالة makeSafe مستعملة في الدالة format_post والكود موجود فوق في هذه الصفحة.

ومع ذلك لا يتم حذف او التعامل مع هذه الحروف ...

اين المشكل في رايكم ؟

[idontknow]

حسنا أخي لنعمل على عزل المشكلة

أولا قم بعمل comment out لكل الدالات التي لديك و حول كل دالة الى الشكل التالي

*/
        return $Str;
    } 

و جرب اضافة الخبر

فان عمل
فابدأ بتشغيل الدالات واحدة واحدة حتى تعود المشكلة من جديد
الدالة التي عادت فيها المشكلة أبقها comment و الباقي شغلهم و تأكد أن المشكلة محصورة في هذه الدالة

الان بعد تحديد الدالة
ابدأ بالسماح بأجزاء من الدالة و ليس كلها
حتى تحدد بالضبط ما هو الأمر في الدالة المسؤول عن المشكلة
بعدها سنتمكن ان شاء الله من حل المشكلة

هذه الطريقة ستحتاج منك تقريبا 5 الى 6 تجارب لكن ان شاء الله يها يمكن تحديد المشكلة

اظن اني وضعت الكود في المكان الخاطيء ...

سوف اجرب من جديد.

كما ذكرت لك سابقا هناك العديد من الحروف الخاصة اسوقها لك في هذا الرابط :
