• PHP parse/syntax errors; and how to solve them? 17 answers

I'm getting an error and I don't know how to resolve it..

The error is:

Parse error: syntax error, unexpected '(', expecting variable (T_VARIABLE) or '$' in C:\xampp\htdocsecords\delete-confirm.php on line 7

Line 7 is:

echo "<script>$(document).ready(function(){$('.modal-" . $row->id . "').hide();$('#delete-" . $row->id . "').click(function(){$('.modal-" . $row->id . "').show();});$('#cancel-" . $row->id . "').click(function(){$('.modal-" . $row->id . "').hide();});});</script>";

I have checked the whole line but there seems no errors in there? What is going wrong here?

Answer 1

By using double quotes " in an echo statement, PHP reads the value of the content inside the quotes. Single quotes ' assign a value to what's between the quotes.

$variable = 'Mia';  // assigns the value Mia to the $variable
echo '$variable';   // output is $variable;
echo "$variable";   // output is Mia;

In your example, wrap literal output in single quotes instead of double quotes and it will solve your problem.

echo '<div class="example" id="' . $variable . '">';
