[SOLVED] Preg_match variables of a certain pattern

[newbtophp]

Im trying to create a preg_match to match variables, which are always 38 characters long and always start with $SPLPF followed by random letters and numbers all uppercase.

 

Example variables:

 

$SPLPFMA7E07CE476A248553FE6D996A078C08

 

$SPLPFF3ACA209490CBA3B3F38DC9C1DA910TC

 

All help is greatly apreciated  :-\

[newbtophp]

Heres my attempt but it doesnt seem to work:

 

/\$SPLPF[A-Z0-9^\d{38,38}$]*/

[Mchl]

#^\$SPLPF[A-Z0-9]{32}$#

[newbtophp]

#^\$SPLPF[A-Z0-9]{32}$#

 

Did you mean?

 

#^\$SPLPF[A-Z0-9]{38}$#

 

and how would i intgrate that within a preg_match:

 

for example

 

 

preg_match('/testing.*#^\$SPLPF[A-Z0-9]{38}$#/'); ?

[Mchl]

No. I meant 32.

Your patter needs to match $SPLPF and then 32 numbers or letters uppercase.

 

As to your other question... what are you trying to do?

[newbtophp]

I meant how would i integrate that variable regex to another regex pattern:

 

like:

 

'/echo\("hey"\);.*^\$SPLPF[A-Z0-9]{32}$/';

 

would placing the variable like that work?

 

also.

 

if(preg_match('#^\$SPLPF[A-Z0-9]{32}$#', $file)) {

echo "match";

}

 

Only seems to work if $file contains just the variable and no other code, is their any modifiers i can add to the regex pattern, so it matches even if theirs more code surrounding that variable.

^ means 'start of line' and $ means 'end of line', so if you need to match these variables anywhere in the line you have to remove these:

 

#\$SPLPF[A-Z0-9]{32}#

 

So joining it with the rest of your pattern:

 

#echo\("hey"\);[^$]*\$SPLPF[A-Z0-9]{32}#

thanks that worked perfect!
