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

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

Firefox reacting to JQuery setTimeout that doesn't apply -

& lt; - Only note the first image. I think some jquery is not working in Firefox, where there seems to be a problem ... but there is IE (I know, I know) var hover = $ ('# par1'), box = $ ('.sq1'); Hover.hover (function () {box.toggleClass ('index2');}); and var linkloc = $ ('# par1'), link = $ ('# frnt1'); Linkloc.on ('mouseenter', function () {function linkadd () {link.html ("& lt; a target = _blank href = http: //www.google.co.uk> & lt; img src = small1 .JPG / & gt; & lt; / a & gt; ");} Set Timeout (linkAD, 1500)}); Linkloc.on ('mouseleave', function () {link.html ("& lt; img src = small1.JPG />");}); I appreciate that the code can be a bit messy, but I'm still learning as I go. The problem now is that the top slice of the code is reacting down to the setout. (It revolves around time with setTimeout repeatedly) even though the name of the function is c...
