return
<<< EOT
<input type="text" name="questao{$this->numQuestao}" value="<?php echo $questao{$this->numQuestao}?>"/>
EOT;
I needed to print this in my file html : <?php echo $questao{$this->numQuestao}?> with $ , however it is giving this error:
Parse error: syntax error, unexpected end of file
If I did with quotation marks, it would work:
return
'value="<?php echo $questao'.$this->numQuestao.'">';
Heredocs error, according to official documentation , occurs when there are characters in the same line as the close handle
It is very important to verify that the does not contain any other characters, except possibly a semicolon (;). This means that the identifier can not be indented, and that there can be no space or tabulations before or after the semicolon.
So if you put EOT; to the page, it should work.
In your case, I think you do not need to use a heredocs, just do the string concatenation
<?php
$campo = 'teste';
return "<input type='text' name='". $teste."'/>";
Your HEREDOC has a space after <<< . Also another problem that occurs is to think that after <<<EOT we can use spaces.
Generally, after the <<<EOT statement comes a line break, the string being written just below.
So:
$x = <<<EOT
minha string de
teste
EOT;
var_dump($x);
Output:
string(21) "minha string de
teste"
Remember that if you tab this string, the size of the tab will be considered.
Look again:
$x = <<<EOT
minha string de
teste
EOT;
var_dump($x);
Output:
string(29) " minha string de
teste"
Note that the EOT; at the end can not be tabbed. It has can not have spaces before.
