Now with php 7 (actually tested on 7.2.2) a normal if statement with a ">=" compare opertor finishes interpreting php. (As it would be expected when i had written "?>" ) On top - dont know if related to the above a function defined inside the <html> <body> tag is not recognized as defined. aamof i defined a function there definetly before its first usage and it does not work. moving it before the <html> <body> tag solves the problem ------------------------------------------------------------------------ [2018-02-19 12:43:53] spam2 at rhsoft dot net it would be a good start to write proper code and then it even works >= 0 when comparing the boolean 'false' triggers implict type-casting and false weak >compared to 0 is the same as int 0 when the string starts with needle that this worked in some arbitary PHP version was just by luck - if(strpos($_SERVER['SERVER_ADDR'],"192.168.10") >= 0) + if(strpos($_SERVER['SERVER_ADDR'],"192.168.10") !== false) ------------------------------------------------------------------------ [2018-02-19 12:41:36] rolf at rolfjentsch dot de Processing a .php document is done wrong imho. When a statement like "if (strpos($_SERVER['SERVER_ADDR'],"192.168.10") >= 0)" is proccessed it does not compare but finishes to interpret (which would be fine if there is a "?>") but the compare option ">=" finishes interpretation of the source and echoes in the above example "= 0)" This appplies to all php 7 versions i have tested so far either on ubuntu or on xammp. ------------------------------------------------------------------------ [2018-02-19 12:18:30] peehaa@php.net It's not clear at all what this bug report is trying to... report.
