PHP variable naming suggestions_PHP tutorial

PHP is a weakly typed language. If there are many variables in the program, and the naming of many functions in PHP is very confusing, it will become more confusing and confusing.

Unified coding style and even variable naming are very important in team development.

I have been engaged in PHP development for many years. In order to make the team I lead more efficient, I have gradually formed a naming habit for PHP (a friend later said it was the Hungarian nomenclature that already existed), making my program look very clear.

I will share my experience with you below. It may not apply to others, but I still want to share it.

string, string type, add str in front of the variable
Copy PHP content to the clipboard
PHP code:
//The next variable is string type
$strMessage = Hello World! ;

array, array type, add a in front of the variable, use singular nouns for one-dimensional arrays, and plural nouns for multi-dimensional arrays
Copy PHP content to the clipboard
PHP code:
//below A variable is a one-dimensional array
$aData = array (1, 2, 3, 4, 5,6);

//The following variable is a multi-dimensional array
$aMembers = array ( id => 123456 , username => ABC , email => abc#abc.com ) ;

integer, integer variable, add n in front
Copy PHP content to the clipboard
PHP code:
//The next variable is an integer
$nCount = $pBS ->Member->getCount() ;

boolean, Boolean type is preceded by b
Copy PHP content to the clipboard
PHP code:
//The next variable is Boolean
$bEncode = true;

float, floating point type, add f in front
Copy PHP content to the clipboard
PHP code:
//The next variable is floating point type
$fSave = 0.8; // 20% off

Pointer type, such as class. Add p in front
Copy PHP content to the clipboard
PHP code:
//The following is an instantiation of a class
$pBP = new BluePage;

resource, resource type, add rs in front
Copy PHP content to the clipboard
PHP code:
$rsConn = mysql_connect (localhost, user, pw);

$rsHandle = fopen( $strFilename );

Unspecified variable, use mx
to copy PHP content to the clipboard
PHP code:
$mxData = getData();

Custom function, start with fn_
Copy PHP content to clipboard
PHP code:
function fn_HaltError ( $strErrorMessage )
{
// do sth. ..
}

A comprehensive example (using pagination class):
Copy PHP content to clipboard
PHP code:
include ( "lib/BluePage.class.php" ) ;
$pBP = new BluePage ;

$rsConn = mysql_connect( localhost , root , 123456 ) or die( mysql_error() ) ;
mysql_select_db( test , $rsConn );

$strQuery = "SELECT COUNT(`id`) FROM test" ;
$nCount = $pBP->myGetCount( $strQuery , $rsConn ) ; //Get the total number
if ( $nCount < ; 1 )
{
fn_HaltError( $aMessages[nodata] ) ;
}
$nShowNum = 10 ;

//Paging array and html
$aPDatas = $pBP->get( $nCount , $nShowNum ) ;
$strHtml = $pBP->getHTML( $aPDatas ) ;

//Paging data contains offset, get the data
$strQuery = "SELECT * FROM test LIMIT " . $aPDatas[offset] . ", " . $nShowNum ;
$rsResult = mysql_query( $ strQuery );
