if I accidently treat array as a string, then ...

[searain]

<?php
$a[0]=0;
$a[1]=1;
echo("a is $a"); //this will tell "a is array"

$b[0]=0;
$b[1]=1;

$b=trim(str_replace("'", "''", $b));
echo("<br>b is $b");  //this will tell "b is array" but actually, $b array is damaged.

for ($index=0; $index<count($a); $index++)
{
	echo("<br>a $a[$index]"); //this will display array $a value
}

for ($index=0; $index<count($b); $index++)
{
	echo("<br>b $b[$index]");  //this cannot display $b value
}

?>

the screen will be

a is Array
b is Array
a 0
a 1
b A

So my question if i accidently apply string function to an array, it will damage the array. Right?
