I'm having an error in submitting the code:
Parse error: syntax error, unexpected '' "> '' (T_CONSTANT_ENCAPSED_STRING), expecting ',' or ';'
The code referring to the error is the second line, is it possible to help? Thanks!
echo '<div class="letras">
<label class="alternativa" for="'.$i+1.'" >'.$letras[$i].',
<input type="radio" name="1" id="'.$i+1.'" value="'.$numabcde[$i].'">'.$randabcde[$i].'
</label>
</div>
}';
Separate numeric expressions with ( ) , otherwise the concatenation happens before the math operation.
Correction:
echo '<div class="letras">
<label class="alternativa" for="'.($i+1).'" >'.$letras[$i].',
<input type="radio" name="1" id="'.($i+1).'" value="'.$numabcde[$i].'">'.$randabcde[$i].'
</label>
</div>
}';
There are other oddities in your code, such as a comma and a } , but only by what was posted in the question, you can not imagine the original intention.
