PHP quick checklist ..

PHP quick checklist The main points:

• Always give PHP pages the correct filename extension, normally .php.
• Enclose all PHP script between the correct tags: <?php and ?>.
• Avoid the short form of the opening tag: <?. Using <?php is more reliable.
• PHP variables begin with $ followed by a letter or the underscore character.
• Choose meaningful variable names and remember they’re case-sensitive.
• Use comments to remind you what your script does.
• Remember that numbers don’t require quotes, but strings (text) do.
• You can use single or double quotes, but the outer pair must match.
• Use a backslash to escape quotes of the same type inside a string.
• To store related items together, use an array.
• Use conditional statements, such as if and if... else, for decision making.
• Simplify repetitive tasks with loops.
• Use functions to perform preset tasks.
• Display PHP output with echo or print.
• Inspect the content of arrays with print_r().
• With most error messages, work backward from the position indicated.
• Keep smiling—and remember that PHP is not difficult.
