PHP 5.4-specific ISSET query regarding $_GET. $_POST Superglobals -


i have upgrade mission-critical (aren't all?) ubuntu server php 5.3 5.4, , happy 1 possible problem. our php scripts include around 1200 isset() references, of check status of either $_get or $_post variables, names comprise strings, not numerics.

i'm aware of (5.3 v 5.4) distinction 5.4 returns false when isset($var['somestringvalue']) used, , query whether unwanted behaviour apply our string-value $_post , $_get variables?

i knock quick 5.4 test server, use many extensions , adjustments that's easier said done. thought i'd try luck here first. in advance.

that not "unwanted behaviour", it's useful. behaviour changes if isset() called on string. 

$string = 'my string'; // length = 9, character indexes 0 8 var_dump(isset($string[5])); // makes sense -> checks whether there's character on 5th position (true) var_dump(isset($string[10])); // makes sense -> checks whether there's character on 10th position (false) var_dump(isset($string['foo'])); // doesn't make sense -> checks whether there's character on "foo" position (false)

since $_get , $_post associative arrays, new behaviour not affect in case. more information, check manual @ http://php.net/manual/en/function.isset.php

ps: should consider development server, test things without creating problems users / customers!

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
