PHP: Expressions - Manual - 0 views

  • (scalar values are values that you can't 'break' into smaller pieces, unlike arrays, for instance
  • Expressions are the most important building stones of PHP. In PHP, almost anything you write is an expression
  • The simplest yet most accurate way to define an expression is "anything that has a value"
  • ...16 more annotations...
  • PHP also supports two composite (non-scalar) types: arrays and objects. Each of these value types can be assigned into variables or returned from functions.
  • PHP is an expression-oriented language
  • Since assignments are parsed in a right to left order, you can also write '$b = $a = 5'
  • and that's the value of the assignment itself
  • A very common type of expressions are comparison expressions. These expressions evaluate to either FALSE or TRUE. PHP supports > (bigger than), >= (bigger than or equal to), == (equal), != (not equal), < (smaller than) and <= (smaller than or equal to). The language also supports a set of strict equivalence operators: === (equal to and same type) and !== (not equal to or not same type). These expressions are most commonly used inside conditional execution, such as if statements.
  • and is assigned back into $a,
  • The last example of expressions we'll deal with here is combined operator-assignment expressions
  • Adding 3 to the current value of $a can be written '$a += 3'
  • This means exactly "take the value of $a, add 3 to it, and assign it back into $a"
  • Any two-place operator can be used in this operator-assignment mode, for example '$a -= 5' (subtract 5 from the value of $a), '$b *= 7' (multiply the value of $b by 7), etc.
  • There is one more expression that may seem odd if you haven't seen it in other languages, the ternary conditional operator:
  • If the value of the first subexpression is TRUE (non-zero), then the second subexpression is evaluated, and that is the result of the conditional expression. Otherwise, the third subexpression is evaluated, and that is the value
  • Some expressions can be considered as statements. In this case, a statement has the form of 'expr ;' that is, an expression followed by a semicolon. In '$b = $a = 5;', '$a = 5' is a valid expression, but it's not a statement by itself. '$b = $a = 5;' however is a valid statement.
  • One last thing worth mentioning is the truth value of expressions. In many events, mainly in conditional execution and loops, you're not interested in the specific value of the expression, but only care about whether it means TRUE or FALSE. The constants TRUE and FALSE (case-insensitive) are the two possible boolean values.
  • Throughout the rest of this manual we'll write expr to indicate any valid PHP expression.
  • Functions are expressions with the value of their return value.

Showcase your best with compelling magazines - 0 views

  •  
    Magazines are among the best medium to express the views and opinions of the company. The best ones are those that balance the content with the designs. An impressive layout, compelling graphics, good content, and related aspects make every business magazine worth the wait. The benefits of having an effective magazine design: A magazine is not a newspaper. It comes out bi-weekly or monthly and hence, should be a keepsake rather than read and discard one. Magazines should be awaited before every release and this wait makes them worthy. Corporates should understand that these papers together create a reputation of the company, not just in the minds of employees but others associated as well.

Accordion Pattern - Design Pattern Library - YDN - 2 views

  • Have the most important panel open by default
  • Accordions may be configured to require that there is always a single panel open or to allow for more flexible possibilities (all panels closed, multiple panels open). Some practitioners consider it a best practice to permit only one panel to be open at a time, but others disagree.
  • For keyboard users an accordion usually ends up behaving either as a tree view or as a tab view.
  • ...2 more annotations...
  • An accordion should degrade into something useful when Javacript is off, perhaps opening all panels.
  • Display none shouldn’t be used as this might hide the content from a screen reader. Instead consider setting a height of 0.
