I am Having Two array like the following ,
$a =array(1,2,3,4);
$b =array(1,2,5,6);
here is mycode
$c=array_diff($a,$b);
$c=array(3,4,5,6);
but i want it like the following
$c=array(3,4);
Note:
i want $a array value which is not present in $b array.
try this
<?php
$array1 = array(1,2,3,4);
$array2 = array(1,2,5,6);
$result = array_diff($array1, $array2);
print_r($result);
?>
read this PHp.NET for array_diff and also refer this FIDDLE
i know array_diff is the best way but dianuj's answer wasnt quite kosher and a comment may not have been communicated well enough.
<?php
$a = array(1,2,3,4);
$b = array(1,2,5,6);
foreach($a as $k => $v)
{
if (in_array($v, $b))
unset($a[$k]);
}
var_dump($a);
If you want to create a new array without maintaining the old keys, try this
$c = array_values(array_diff($a, $b));

This should do it for you.
// get differences that in ary_1 but not in ary_2
foreach ( $ary_1 as $v1 ) {
$flag = 0;
foreach ( $ary_2 as $v2 ) {
$flag |= ( $v1 == $v2 );
if ( $flag ) break;
}
if ( !$flag ) array_push( $diff, $v1 );
}
where :
$ary_1 = $a & $ary_2 = $b
array_diff()should do exactly what you want. It works for me - codepad.viper-7.com/tMTzzG$c=array_diff($b,$a);$bthat are not present in$a.$c=array(3,4,5,6);
