How to add css style in php

Using php, you can output HTML tags, which brings great convenience to page design.

Record here the problem of setting CSS style for php output tags:

echo can use '', "" or you don't need quotes, If you want to output HTML tags with CSS style , just use 'echo' to output.

About the differences between the three echo outputs:

1. Integer values ​​can be output directly. Numbers and the like can be output directly without quotation marks.

2. The output variable can also be output without any quotation marks. Just echo $a;. To output characters, you must add quotation marks. For example, echo "Hello world!";

3. Regarding single quotes and double quotes, there is only one difference. Variables and operators in single quotes will not be interpreted. Output as is. The content in double quotes will be interpreted as the corresponding content.

For example
$a=1;
echo "$a"; //Output 1 variable is interpreted.
echo '$a'; //The output $a variable is not interpreted.

If you want to output characters and variables together, use double quotes. If you are just outputting plain text content, you can use single quotes.

For example:
echo "c858d69dd81008e347cd5f5447f8e393$ae6e38b3c62e8df885fe2e3986461aa63";
echo 'c858d69dd81008e347cd5f5447f8e393Hello world!e6e38b3c62e8df885fe2e3986461aa63';

PHP scripts can also introduce css styles. The code examples are as follows:

css statements:

<style type="text/css">
table {
 margin: 8px;
}
th {
 font-family: Arial, Helvetica, sans-serif;
 font-size:. 7em;
 background: #666;
 color: #FFF;
 padding: 2px 6px;
 border-collapse: separate;
 border: 1px solid #000;
}
td {
 font-family: Arial, Helvetica, sans-serif;
 font-size:. 7em;
 border: 1px solid #DDD;
}
</style>

PHP statements refer to css styles:

<?php>
echo"<table>";
echo"<tr><th>ID</th><th>hashtag</th></tr>";
while($row = mysql_fetch_row($result))
{
 echo"<tr onmouseover="hilite(this)" onmouseout="lowlite(this)"><td>$row[0]</td> <td>$row[1]</td></tr>n";
}
echo"</table>";
<?>
