How to fix “Headers already sent” error in PHP -


इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 11 जवाब

मेरी स्क्रिप्ट चलते समय, मैं इस तरह से कई त्रुटियां हो रही हैं: 

  चेतावनी: हेडर सूचना को संशोधित नहीं किया जा सकता है - हेडर पहले से ही प्रेषित (/some/file.php:12 पर आउटपुट) /some/file.php में लाइन पर 23

त्रुटि संदेशों में उल्लिखित लाइन में हैडर () और setcookie () कॉल हैं।

इसका क्या कारण रह सकता है? और इसे कैसे ठीक करें?

इस प्रकार की समस्या तब होती है जब आप हेडर आपके पृष्ठ में लिखने के बाद। मुझे लगता है कि आपको कोड जैसा दिख सकता है :: 

  & lt; html & gt; & Lt; शीर्ष & gt; & Lt; title & gt; शीर्षक & lt; / title & gt; ......... & lt; / head & gt; & LT; बॉडी & gt; ..... और & lt;? Php हेडर () / कुछ शीर्षलेख जांचना? & Gt; ..... & lt; / body & gt; & Lt; / html & gt;

यदि ऐसा है, तो html से पहले हैडर () का उपयोग करें या किसी प्रकार की गूंज या लेखन कोड लेकिन यह सही समाधान नहीं है आप ob_start का उपयोग कर सकते हैं। यह सबसे अच्छा समाधान है जांचें

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
