what difference between = , == , , === ? i think using 1 equal sign declare variable while 2 equal signs comparison condition , lastly 3 equal signs comparing values of declared variables. you have = assignment operator , == 'equal' comparison operator , === 'identical' comparison operator . $a = $b assign sets $a equal $b. $a == $b equal true if $a equal $b. $a === $b identical true if $a equal $b, , of same type. (introduced in php 4) for more info on need == , === , , situations use each, @ the docs .
