What is wrong with this piece of code?

[whitey]

[code=php]<?php
echo "<table style=\ "border: 1px solid black;\">\n;
for ($y=1; $y<=12; $y++) {
echo "<tr> \n";
for ($x=1; $x<=12; $x++) {
echo "<td style =\ "border: 1px solid black; width: 25px; padding: 4px;
text-align:center;\" >";
echo ($x * $y);
echo "</td> \n";
}
echo "</tr> \n";
}
echo "</table>";
?>[/code]

i noticed a " was missing after the "n" on line two, but still no joy

Check this out: There were some errors while closing the the echo Strings.
[CODE=php]
<?php
echo "<table style=\"border: 1px solid black;\">\n";
for ($y=1; $y<=12; $y++) {
echo "<tr> \n";
for ($x=1; $x<=12; $x++) {
echo "<td style =\"border: 1px solid black; width: 25px; padding: 4px;
text-align:center;\" >";
echo ($x * $y);
echo "</td> \n";
}
echo "</tr> \n";
}
echo "</table>";
?>
[/CODE]

EDIT:

ALWAYS use single quotes instead of double quotes. Then no more "Escape" (\) characters.

[CODE=php]
<?php
echo '<table style="border: 1px solid black;">';
for ($y=1; $y<=12; $y++) {
echo '<tr>';
for ($x=1; $x<=12; $x++) {
echo '<td style ="border: 1px solid black; width: 25px; padding: 4px;
text-align:center;"> ';
echo ($x * $y);
echo '</td>';
}
echo '</tr>';
}
echo '</table>';
?>
[/CODE]

Heya, Whitey.

Please use CODE tags when posting source code:

&#91;CODE=ph p]
PHP code goes here.

It is worth it to note however, that if there is a variable inside single quotes, it will not be evaluated. I typically use " to start and end an echo, and single quotes within it, as this allows variables to be evaluated.

for the OP:

[PHP]<?
$var = "HELLO WORLD";
echo "$var";//echo's HELLO WORLD
echo "<br />";
echo '$var'; //echo's $var
echo "<br />";
echo "123 '$var'"; // echo's 123 'HELLO WORLD'
?>[/PHP]

<?php

echo "Yes its easy with double quotes: like this $myvar"; //prints: Yes its easy with double quotes: like this When_you_evalua te_php_variable s
echo '<br>';
echo "<font type=\"verdana\ " color=\"red\">B ut This way is hard $myvar With HTML Tags.</font>"; //prints: But This way is hard When_you_evalua te_php_variable s With HTML Tags.
// In above line you have to use "Escape" for each ["] character within the HTML coding
// But Its easy with single Quotes, With This Way"
echo '<br>';
echo '<font type="verdana" color="red">But This way is Eazy '.$myvar.' With HTML Tags</font>';

Think about a situation that you have to "echo" (only echo) some CSS/HTML tags with Php. Then what is so easier "Double quotes" or "single quotes" ? Real world Web application, ALWAYS not pure php. Its combination of PHP,HTML,CSS. So are you going to escape the double quotes when echoing? Its good for hello world Apps!

For large amounts of HTML, it's a lot easier (and potentially more efficient) to use heredoc syntax:
[code=php]
echo <<<END
<div style="border: 1px solid #ffff00; padding: 8px;">
With heredoc, you can evaluate all the {$var}s you want, and you can use<br />
<span style="color: #00ffff">quotes ' " ' " &quot;, too!</span>
</div>
END;
[/code]

The code syntax parser here at TheScripts isn't picking it up, but heredoc is valid:

[ak1dnar]

you are so correct pb, and always.
I don't know why I hate this "heredoc".

[pbmods]

Heya, Ajaxrand.

A good templating engine will defeat the need for heredoc any day. That's why you hate it so :)

Hey Ajaxrand,

I wasn't trying to discount your advice, you are correct. When echoing HTML I usually use double quotes to start the string and single quotes for my html. Works just the same. That's what I was trying to get across.

Thanks,

Greg
