Trouble with sscanf() in PHP

bad scan conversion character

[lorax]

Hola,
Been trying to use sscanf() on a blob field to extract certain chunks of the string. The field contains a string like this "M 808511 224661 L 1073864 365898 L 1045927 820407..." so I'm trying to create arrays based on delineators M, L, and Z.

My code reads

$m = sscanf($geometry["Geometry"], "%p %x %y");

for the Ms. There isn't much documentation on this function and the error doesn't quite make sense - and I've never worked with blob fields before. Some guidance would be appreciated.

sscanf is best used for something that has a standard repeating pattern. Is that what you are working with or does the pattern of the data change?

If it changes you would be better matching it with regex.

Thanks jatar_k,
The pattern is the same but the number of characters does change. I'm beginning to think you're right - I'll try regex instead.
