memory_used_pct()

Return the percentage of script memory still available. Useful as a safety valve in a long loop that builds up a lot of data.

Syntax

memory_used_pct()

Parameters

None.

Returns

A number — the percentage of memory remaining (100 = none used).

Example

foreach ( $bigList as $row ) {
    // ... process row ...
    if ( memory_used_pct() < 10 ) {
        sys_log("Low on memory, stopping early");
        break;
    }
}

Example output

87.4

Notes

A niche helper for very large batch operations — most flows never need it.
