I am trying to understand this syntax <?=$value;?> in php, For example:
<input type="text" name="user" value="<?=$_POST["user"];?>" id="user">
As i understand it is not some xml syntax becouse the file has to be .php file, Also the:
<? ?> // short opening tags in the <?=$_POST["user"];?> syntax
Is working even if i set short_open_tag = Off, If anyone can please help me understand this syntax and how doe's it working with the short_open_tag = Off, Thank you all and have a nice day.
try
<input type="text" name="user" value="<?=$_POST['user'];?>" id="user" />
You forget " .
And <?=$_POST['user'];?> is the simple and short form of <?php echo $_POST['user']; ?>
The <?=$value;?> is short-hand syntax for <?php echo $value; ?>.
As to why it works even with short_open_tags turned off; are you using PHP >=5.4.0? If so, that's expected; it's always available. See here.
<input type="text" name="user" value=<?=$_POST["user"];?> id="user">
value=<?=$_POST["user"];?>
Means the value you entered in the input field with name 'user' and submitted.
<? ?> is the same as <?php ?>. Since they are inserting a php value $_POST["user"] into the Form they are using the <? ?>
short_open_tagis depreciated..please dont use that<? echo $_POST["user"]; ?>
