php - Combining two preg_replace into one -

-

I want to add those 2 preg_replace to one. For example data-thumb-bg = " with style =" background-image: url (' and followed by if .jpg replace it with , .jpg); . $ Input = preg_replace ('# data-thumb-bg = "# s',' style =" background-image: url (', $ input); $ input = preg_replace (' # .jpg # s', '.jpg);', $ input); // This will be executed only when one of the above matches

How can I do this?

Edit

I think I have expressed myself wrongly

.jpg to only data-thumb-bg = has been changed. As you change the data-thumb-bg , you replace .jpg with data-thumb-bg

Kind regards

I assume that your ultimate goal is to change the attribute of an element < Code> data-thumb-bg = "photo.jpg" to style = "background-image: url (photo.jpg);" This can be used one more (note that since we do not use . is unnecessary): 

  $ input = Preg_replace ('/ data-thumb -bg =' ([^ "] + /", 'style = "background-image: url (\ 1);"', $ input);
< P>

If you only want to allow, you can use this expression: 

  data-thumb-bg = "([^ "+ ... .jpg]"

Or if you only want to allow, you can use an expression like this: 

  date -thnb-BG = "([^"] +? \. (?: Jpe? G | png | gif)) "

python - mayavi mapping a discrete colorbar on a surface -

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
