陣列array

php程式碼之一

$test[] = 'strA';   

$test[] = 'strB';   

//Array ( [0] => strA [1] => strB )

$test['a'] = 'strA';   

$test[] = 'strB';   

//Array ( [a] => strA [0] => strB )

$test[3] = 'strA';   

$test[] = 'strB';   

//Array ( [3] => strA [4] => strB )

php程式碼之二

$test[3] = 'strA';

$test[4] = 'strB';

//Array ( [3] => strA [4] => strB )

$test['5'] = 'strA';

$test['8'] = 'strB';

//Array ( [5] => strA [8] => strB )

$test['c'] = 'strA';

$test['d'] = 'strB';

//Array ( [c] => strA [d] => strB )

php程式碼之三

$test = array('strA','strB');

//Array ( [0] => strA [1] => strB )

$test = array('a'=>'strA','20'=>'strB');

//Array ( [a] => strA [20] => strB )

php程式碼

$test = array('strA','strB');

foreach ( $test as $value ){

     echo $value;

}

//strAstrB

$test = array('strA','strB');

foreach ( $test as $key=>$value){

     echo $key.'=>'.$value;

}

//0=>strA1=>strB

$test = array('strA','strB');

for ( $i=0;$i<count($test);$i++){

     echo $test[$i];

}

//strAstrB

print_r($test);

//Array ( [0] => strA [1] => strB )

var_dump($test);

//array(2) { [0]=> string(4) "strA" [1]=> string(4) "strB" }
