php - The str_ireplace and preg_replace attemt? -

-

I am trying to replace a string with one original text. ( zinc -> gt; zn ) Example: 'zinc zinc zinc zinc 3! Zinc Zodiac # Zinc Zinc 9 Zinc @ zinc @ want to: 'zn zn zn zinc3! Zn zincmatic #zinc zinc9 zn @zinc @ stack_replayed attempts: $ text = 'zinc zinc zinc zinc 3 ! Zinc zodiac # zinc zinc 9 zinc @ zinc @ '; $ Word = 'zinc'; $ Attr = 'zn'; // cnt as str_ireplace will now be converted to zinc znmatic and # zinc #zn $ text = ''. $ Text will change in ''; $ Word = ''. $ Zinc ''; // will now try $ result = str_ireplace ($ word, $ attr, $ word); Echo trim ($ result);

Print zn zinc zn zinc3! Zinc zinc # zinc zinc 9 zn @ zinc @ .

Preg_replace attempts: P> 

  $ text = 'zinc zinc Zinc zinc 3! Zinc zodiac # zinc zinc 9 zinc '; $ Word = 'zinc'; $ Attr = 'zn'; $ Result = preg_replace ("/ \ b ($ word) \ b / i", $ attr, $ text); $ Return result;   
 Print  zn zn zn zinc3! Zn zincmatic #zn zinc9 zn @zn @  Almost what I want: It seems that in zinc,  zn  even if some special character near ! Zinc is  or  # zonx  but if any number is  zinc9  or  junkmic like text   
 I just have one I want to put the rule here so that  # zinc  is passed to  # zink ,  @ zinc @  to  @zink_  and ! Zinc  to ! Zn changes into   
 What to add is the exception of special characters if zinc is near one of them (i.e.:  #zinc ,  Zinc # < / Code>,  zinc@ ,  @ zanx )  
 I want to be an executable, the letter is  # ,  and ,  @   
 Thanks!  
  
 
 
 You can define such exceptions with negative  \ b  Behave like and can actually be used in conjunction.  
 In your case you want  (? & Lt;! [# & Amp; @])  to check the previous character, and  (?! [ # & Amp; @]) Click .  
  = preg_replace ("/ (? & Lt;?! [# & Amp; @]!) \ B ($ word) \ b ([# & amp; @]) / I ", $ Attr, $ text);

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

ruby on rails - Convert a Activerecord result with has_one associations into a single hash per record -

-
If I have any results from the Active Records, then I have an array of hashes, if I have a reliable load, then every Each organization hash in record hash has a nested hash of its associated records My question is, is there a quick rail system that allows you to merge these nested hashes into a hash per record? An analogy will be changing the records table rows Another resemblance will be converted into a hash at one level of nested hashes. approach 1: select them in the section Include class user has_one: profile end is for square profile: user # street 1, street 2, city etc. end profile = profile.junks (user :). Selection ("User. *, Profile. *") All profiles. First.login Approach 2: Use delegation for class profiles : User # Street 1, Road 2, City etc. Representative: Name ,: name =,: email,: email = ,: from = to & gt; : End of user

javascript - Read complete data from stream from onMessage -

How to read event.data from a web site entirely using javascript ? On Message: Function (Event) {var msg = event.data; Warning (msg); } In the above code, variable msg shows only partial data How to obtain complete data from websicet server? event.data contains complete information; It depends only on your output how much you will see. A warning box only contains a special number of characters, because more characters do not fit in the warning box only. Warning ing is not a good practice to display large data. A more convenient way to save the length and to check that, for example: On Message: Function (Event) {var msg = event.data; Warning (msg.length); } The length should be just the right length, that is the length of the characters you sent.
