PHP Echo a large block of text

Question

Im new to PHP and I can\'t figure out what the rules are for using the echo function. For example, if I need to echo a large block of css/js, do I need to add echo to each line

Answer 1

I prefer to concatenate multiple Strings together. This works either for echo AND for variables. Also some IDEs auto-initialize new lines if you hit enter. This Syntax also generate small output because there are much less whitespaces in the strings.

echo ''
    .'one {'
    .'    color: red;'
    .'}'
    ;

$foo = ''
    .'
' . $bar . '
'  // insert value of bar
    .$bar                     // insert value of bar again
    ."
$bar
"            // and again
    ."
You can also use Double-Quoted \t Strings for single lines. \n To use Escape Sequences.
"
    // also you can insert comments in middle, which aren't in the string.
    .'
Or to insert Escape Sequences in middle '."\n".' of a string
'
    ;

Normally i start with an empty string and then append bit by bit to it:

$foo = '';

$foo .= 'function sayHello()'
    .'    alert( "Hello" );'
    ."}\n";

$foo .= 'function sum( a , b )'
    .'{'
    .'    return a + b ;'
    ."}\n";

If they don't find "their" solution they would open a new Question. Then the first five answers are only "use the search function before you ask!" So. I give you another solution to solve problems like this.)
