note 88950 added to language.types.string

This is an interesting scenario: If I pass: $var1 = 0; if($var1=="some_string") { echo "this returns true only for 0"; } How can it return true when comparing an integer of 0 to any string? My guess is that its reading 0 as false and seeing the string as a "false" integer: hence, false == false. Am I right? The solution is to convert the integer to a string; $var1 = 0; $var1 = (string) $var1; if($var1=="some_string") { echo "this returns false"; } ---- Server IP: 209.41.74.194 Probable Submitter: 67.177.5.164 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/88950 Del: integrated -- https://master.php.net/note/delete/88950/integrated Del: useless -- https://master.php.net/note/delete/88950/useless Del: bad code -- https://master.php.net/note/delete/88950/bad+code Del: spam -- https://master.php.net/note/delete/88950/spam Del: non-english -- https://master.php.net/note/delete/88950/non-english Del: in docs -- https://master.php.net/note/delete/88950/in+docs Del: other reasons-- https://master.php.net/note/delete/88950 Reject -- https://master.php.net/note/reject/88950 Search -- https://master.php.net/manage/user-notes.php
