I have this data file, it goes like
phi1_32_1 = 1 phi2_32_1 = 32
phi1_32_2 = 1 phi2_32_2 = 33
phi1_32_3 = 1 phi2_32_3 = 34
phi1_32_4 = 1 phi2_32_4 = 35
phi1_32_5 = 1 phi2_32_5 = 36
... and so on.
I want to read this file into matlab and store as it is. Where for example
the phi1_31_1 is the name of the variable and the value stored in it is 1
the phi2_31_1 is the name of the variable and the value stored in it is 32
... and so on.
Any help is much appreciated. I thank those who would be taking their time to help me, in advance...

Thought it might be helpful for iteration by iteration debugging...

Debugging is also a matter of practice.

Assuming you have a file with only following line (name of file= 'algo.txt'):
phi1_32_1 = 1
You could then read the line with the following command:
fid=fopen('algo.txt','r');
a=fscanf(fid,'%s');
eval(a)
whos
I hope it is useful.

Got an error message
Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To
construct matrices, use brackets instead of parentheses.
