What are the Array Operators?
|
|
Explanation |
|
Following are the Array Operators in PHP
| Example |
Name |
Result |
| $a + $b |
Union |
Union of $a and $b. |
| $a == $b |
Equality |
TRUE if $a and $b have the same key/value pairs. |
| $a === $b |
Identity |
TRUE if $a and $b have the same key/value pairs in the same order and of the same types. |
| $a != $b |
Inequality |
TRUE if $a is not equal to $b. |
| $a <> $b |
Inequality |
TRUE if $a is not equal to $b. |
| $a !== $b |
Non-identity |
TRUE if $a is not identical to $b. |
The + operator appends elements of remaining keys from the right handed array to the left handed.
If there is an array "a" having values "red", "green", and an array "b" having values "blue", "orange","pink" when we use
"+" operator to add these two arrays like "c=a+b", the array c will have values "red", "green","pink".
But when these two arrays are added like "c=b+a", the array c will have values "blue", "orange","pink".
