How to remove time and memory from 500 internal error - Zend

You could match 1 or more digits, then a dot and again 1 or more digits and assert what is on the right is either a pattern {...} or 1+ word characters followed by a \ to make it a bit more specific.

^\d+\.\d+(?={[^{}]*}|\w+\\)

In the replacement use an empty string.

Explanation

• ^ Start of string
• \d+\.\d+ Match 1+ digits, a dot and 1+ digits
• (?= Positive lookahead, assert what is on the right is
  • {[^{}]*} Match { till } without matching { or } in between
  • | Or
  • \w+\\ Match 1+ word chars followed by \
• ) Close lookahead

If you also want to remove the #TimeMemoryFunctionLocation, you could make use of the \G anchor

(?:#TimeMemoryFunctionLocation\R|\G)\d+\.\d+((?:{[^{}]*}|\w+\\).*\R*)

• (?: Non capture group
  • #TimeMemoryFunctionLocation\R Match #TimeMemoryFunctionLocation and a unicode newline sequence
  • | Or
  • \G Assert position at the end of the previous match, which will in this case at the start of the string
• ) Close group
• \d+\.\d+ Match 1+ digits, a dot and 1+ digits
• ( capture group 1
  • (?:{[^{}]*}|\w+\\)
  • .*\R* Match the rest of the line and 0+ unicode newline sequences
• ) Close group 1

In the replacement use capture group 1

For example

$re = '/(?:#TimeMemoryFunctionLocation\R|\G)\d+\.\d+((?:{[^{}]*}|\w+\\\\).*\R*)/';
$str = "...";
$result = preg_replace($re, '$1', $str);

For example, using the first pattern:

$re = '/^\d+\.\d+(?={[^{}]*}|\w+\\\\)/m';
$str = '#TimeMemoryFunctionLocation
