I’ve been experimenting with PHP lately and decided to rewrite my anido C snippet for making texture animations. No more need to download and compile. 
Parameters:
c = columns
r = rows
w = frameWidth
h = frameHeight
i = interval
Example use:
curl "https://dry.luckeyproductions.nl/tools/anido/?c=5&r=3&i=1.25" > animation.xml
Example output:
<texanim uv="0 0 0.2 0.333" time="0" />
<texanim uv="0.2 0 0.4 0.333" time="1.25" />
<texanim uv="0.4 0 0.6 0.333" time="2.5" />
<texanim uv="0.6 0 0.8 0.333" time="3.75" />
<texanim uv="0.8 0 1 0.333" time="5" />
<texanim uv="0 0.333 0.2 0.667" time="6.25" />
<texanim uv="0.2 0.333 0.4 0.667" time="7.5" />
<texanim uv="0.4 0.333 0.6 0.667" time="8.75" />
<texanim uv="0.6 0.333 0.8 0.667" time="1" />
<texanim uv="0.8 0.333 1 0.667" time="11.25" />
<texanim uv="0 0.667 0.2 1" time="12.5" />
<texanim uv="0.2 0.667 0.4 1" time="13.75" />
<texanim uv="0.4 0.667 0.6 1" time="15" />
<texanim uv="0.6 0.667 0.8 1" time="16.25" />
<texanim uv="0.8 0.667 1 1" time="17.5" />
