PHP widely used for web development. More than 80% websites on internet are built using php. In this article i\u2019ll tell you 10 most useful tips for php. <\/span><\/p>\n

1. Always Use long open tags<\/h3>\n

When you declare a php script always use long tags <?php<\/code> instead of short tags <?<\/code>. Because php configuration on most servers do not allow short tags hence your code will not work.<\/p>\n

2. Use error reporting<\/h3>\n

Turn on error reporting on your development server this will help you to find errors in your php code. To turn on error reporting on your server edit php configuration file php.ini<\/code> and set following variables<\/p>\n

error_reporting = E_ALL\ndisplay_errors = On\n<\/pre>\n
If you want to enable error reporting in just current script then add following two lines on top of your php script<\/p>\n
ini_set('display_errors',1);\nerror_reporting(-1);\n<\/pre>\n
3. Use echo instead of print<\/h3>\n
Echo is slightly faster than print and echo can take multiple parameter while print takes only one. So always try to use echo instead of print function.<\/p>\n
4. Know the Difference Between Single and Double Quotes<\/h3>\n
Single quoted strings<\/strong> will display things almost completely “as is.” Variables and most escape sequences will not be interpreted. The exception is that to display a literal single quote, you can escape it with a back slash \\'<\/code>, and to display a back slash, you can escape it with another backslash \\\\<\/code><\/p>\n
Double quote strings<\/strong> will display a host of escaped characters (including some regexps), and variables in the strings will be evaluated. An important point here is that you can use curly braces to isolate the name of the variable you want evaluated. For example let\u2019s say you have the variable $type<\/code> and you what to echo \"The $types are\"<\/code> That will look for the variable $types<\/code>. To get around this use echo \"The {$type}s are\"<\/code> You can put the left brace before or after the dollar sign.<\/p>\n
Example<\/p>\n
$name='sunny';\necho 'my name is $name'; \/\/ my name is $name\necho \"my name is $name\"; \/\/my name is sunny\n<\/pre>\n
5. Use inline comment<\/h3>\n
Always use inline comments to annotate your code. It will help to understand the code so anyone can easily modify it in future. Read more about comment in php<\/a><\/p>\n
6. Don\u2019t Store Passwords as Plain text<\/h3>\n
Most php beginners  store passwords as plain text in database which can be viewed in database that is not safe. So always use md5<\/strong> or sha1<\/strong> to encrypt sensitive data like passwords before storing it in database.<\/p>\n
example<\/p>\n
$passHash=sha1(\"password\");\n<\/pre>\n
7. Filter and validate form data<\/h3>\n
Never trust user as they can input any arbitrary code in form which may leads to XSS (cross-site scripting) attack or sql injection. To protect your script from such vulnerability always validate and filter form data before processing.<\/p>\n
8. Use cache in heavy Script<\/h3>\n
Most heavy php code takes much time to generate output which casts bad impact on website. To speedup your script always use caching in php script. Here are few caching scripts for php<\/p>\n
